Find your own animation, part 1

Today in class I had an animation of the cardiac cycle. It was fabulous, wasn't it?
Actually, in all seriousness, a lot of physiology makes more sense if you can watch it moving. I got that animation from a textbook company, but you can find more online. To post a comment here, you need to:
1. Find a NEW animation of the cardiac cycle online (that nobody above you has mentioned)
2. Give the link, and
3. Say what you like or don't like about this particular animation, or what it helped you understand.

Allow me to start by saying what I did not like about this animation. It used terms that I was unfamiliar with, seeming to indicate that there are other ways of approaching the cardiac cycle. It could be that ours is just simplified and this one is a bit more detailed. Now there are a lot of aspects of this animation that I enjoy. It divides the systole and diastole at the bottom of the animation to indicate what phase the heart is in. It also has the word "contraction" flashing under ventricle or atrium depending on which is contracting. This really helped me understand what phase is associated with the different parts of the cardiac cycle. It also has these nice graphs on the side that help me understand different aspects of the heartbeat. It also has a handy tutorial section that allows us to see specific phases in the cardiac cycle in a piecemeal manner that simply helps me see each individual component. It's very detailed and great for gaining a better understanding of the cardiac cycle.

I think this animation is not the best of quality but it does a very thorough job in explaining the Cardiac Cycle. It's simplicity is deceiving because it shows the AV and semilunar valves opening and closing during the appropriate times of the cycle. I liked this video because it is straightforward. But, I do not like how little detail it shows.

I found this animation rather helpful. It simplified many of the key terms into bullet points that were easy to understand and remember. It also separated the parts of the cycle into different narration's so you could listen to them individually and truly grasp what each one specifically means. It also is very specific on what valves work during what stages which is helpful. Overall I found this animation to be a helpful source in backing up what we learned in lecture.

What I really like about this animation on the cardiac cycle is that not only does it illustrate the actions that the animation in class did, it also shows the blood filling in the ventricles, the amount of pressure in the aorta and the ventricles during each step of the cycle, and shows approximately how quicky the cycle occurs in accordance with one heart beat. The one downside to this animation is that it doesnt show the cycle in slow motion so it may go to quickly to learn without prior knowledge or another diagram.

The animation of cardiac cycle in this site is different from the animation we watch in class today.

I think the animation I find moves too fast, and it is difficult for us to understand the cardiac cycle. It does not have someone to explain each cycle for us. It only has the labels of where the blood from and arrow that indicates the direction the blood flow, but it does not have labels of different part in the heart that is important to understand the cardiac cycle.

However, this animation provide us more information than the animation we watch in class. It shows how the heart work in our body by showing us the continuous contraction. It also shows us heart sound and electrocardiogram, which are quite interesting. We can also see the cardiac cycle of the heart in higher motion, indicates the contraction of heart when we are exercising. It also shows us the excitation signal of the heart during the cardiac cycle.

What I really like about this animation is that it allows the user to click on the description on the right side of the panel and it'll play the corresponding animation on the right. This enables the view to more clearly see the different steps in the cardiac cycle. The descriptions on the left of the panel even though are simple, but they capture the essence of various stages.
One thing I don't like about the animation is that it neglects to show the difference in the number of flaps of biscupid and tricuspid valves. Furthermore, the animation would also be clearer if the heart's various regions had been labeled (i.e. different valves, aorta, atria etc).
In short, this animation is only good for users who already different parts of the heart since it requires this prior knowledge in order to understand the description.

This video only focuses on the aortic valve, and truth be told, it's not very enlightening. However, it is very catchy and hilarious, and it's one aspect of the cardiac cycle I'll probably never forget that "physiology during systole, the aortic valve is open" and that "physiology during diastole, the aortic valve is closed"

In all seriousness, I thought this was pretty helpful:

Although the actual diagram of the heart is very very basic, it helps get the point across. It only shows the left heart, which also helps simplifies the cardiac cycle. I like that the animation shows the relationship between pressure and volume during each stage. There is also a very clear and slow narration. The heartbeat sound effect also helps a lot.

This is definitely the oneline website describing the cardiac cycle "to die for". It tells it all and alittle more. Somewhat directed to the medical student but very detailed in gaining an understanding of how the heart beats.

The quality of this animation is not great at all. However, it does help to show that blood goes out of the left side and in through the right side. This animation is much more broader compared to the one we saw in class.

Because this animation is more broad I do not feel like it explains the cycle well at all. Even though it gives you the big picture it is not showing what is going on inside the heart and does not show the four sections of the heart well. This video makes it seem like there are no valves that need to open and close to allow blood to flow and that it just freely flows throughout the heart and body. Maybe this animation would be good to get "the big picture" view of blood flow but not necessarily the cardiac cycle.

I enjoyed this animation because it allows viewers to choose between normal heart rhythm and slow motion videos. This is interesting to see and compare. However, I do believe other animations were more helpful because they allowed viewers to click through each step of the animation as well as they provided information and a description of each stage of the cycle which this animation did not do a great job of. This animation is good if you want to see how an actual heart works and at what speed the cycle operates.

This animation has the basics: shows blood flow, labels of each part of the heart, and is color coded. On the side of the animation there are also other animations of time and heart sounds. Those animations give a better perspective to the viewer on how the heart beats and work. As the heart beats, the ventricles contract, pushing the blood through the aorta and artery to the lungs or body. Another thing I like about this animation is that the cycle is lit up with half of the stages labeled as systole and the other half diastole.

This animation shows what each stage of the cycle is, however there are more than 5. The ventricular ejection has been split into two stages. According to the animation it is rapid ejection and reduced ejection. Then right before diastole, a stage called rapid ventricle filling occurs, according to the animation. I'm not sure if these stages are correct. Another thing I do not like about the animation is the blood flow is not animated well enough as the one shown in class. The one shown in class explains how the blood pushing back against the AV and the semi lunar valves that keeps the valves closed.

The animation itself was very hard to understand, especially if one was to learn the cardiac cycle for the first time using this animation. First of all, the picture of the heart is very simple, and nothing is labeled. Also, the animation moves fairly quickly and it is hard to see the steps or phases of the cycle. In addition, the animation does not indicate the flow of the blood, which makes this animation pretty impossible to learn from. I think the animation from class and some of the ones that others have listed here are much better and more effective in actually teaching the cardiac cycle than this one that I have found.

I believe that this animation to be very helpful just in terms of explanation. At first, you are able to examine each step slowly and carefully and there is an explanation of how each stage in the cardiac cycle takes place and the diagram changes when you move from one stage to the next. Also, the movements of the heart can be seen as a whole right after all the explanations. It is straight forward, easy paced, and colorful with symbols that you are able to recognize in order to determine the various functions of the heart and its cycle.

Although I can't help but love the boring narrator of this animation, I did not find it too helpful. The heart is never shown contracting and leads to confusion on how the blood gets through the semilunar valves from the venticles. It did however illustrate the path of the blood with a bright red color, and although it was not specific on how the blood got to each new location, it did help remind me of the pattern that the blood takes around the heart.

I thought this was a good animation of the various stages of a heartbeat. The website provided detailed backgorund information on heart rhythm, in addition to other heart information. Finally, during the actual animation, a detailed explanation of the step was provided. I liked the animation because it had a lot of different colors for the different parts involved, which makes it easy for the viewer to keep track of everything. The only thing I didn't like about this animation was the it was on the slow side, however, since a lot of information is provided, I guess it is good to allow the viewer time to digest everything.

What I liked about this animation was that it was very simple, but the over-simplified portrayal of the Cardiac cycle and speed of this animation made it very difficult for me to understand what was happening in the heart besides the pumping of the heart and the AV valves opening. Therefore, I did not like this animation for my learning purposes. For someone to get a clear picture in their minds of how the heart is specifically functioning, one would have to know all the parts of the heart first, and fully understand the cardiac cycle. Once they understand the cycle, I think this diagram would serve as the purpose of memory recall of what they previously learned about the heart.

There are actually two different animations on this website. The first one is helpful in understanding how the left and right hearts work separately, but it neglects to help the viewer understand blood movement through the left and right heart simultaneously. It would be even more helpful with some type of narration.

The second animation provided by this site shows blood flow through the left and right hearts, and provides a thumping sound, which helps to understand what doctors are visualizing when they use a stethoscope to listen to our heart beat. I thought that was helpful since the animation emphasizes which AV valves and semilunar valves open/close with each thump. The heart in this animation is connected to lungs, which may confuse the viewer since it seems as if the blood that just exited the pulmonary artery is the same blood that’s entering the pulmonary vein.

To begin, I would like to state that this animation was quite useful. It allowed me to see the heart's cardiac cycle with full labeling of the different parts of the heart. I was able to distinguish which valves were open and closed during systole and diastole. Also, I was able to see the direction of blood flow through the heart. It would have been better, though, if the direction of blood flow was more distinct. Also, if each phase was more detailed it would help me understand the animation better. Another flaw is that the animation is a demo version, this demo version stops its use after a while on the website. You must refresh the website in order for the animation to work again. In conclusion, I felt this animation was well made and is useful enough to gain a better knowledge of the cardiac cycle.

I liked this animation because it was able to show how the blood was flowing through the atria and the ventricles in a simplified manner. I also liked the fact that it showed deoxygenated blood as blue and oxygenated as red. What I did not like was that the animation went so quickly that it was hard to grasp the concept of when the atria were in systole or diastole and when the ventricles were in systole or diastole. If this animation went slower and was able to not only show but to also say when the ventricles and atria were contracting and relaxing, I feel this would have been a great animation.

This website has the links to several different animation links that correspond to each other.

What I like about the links is that the links are separated by blood flow, cycle stages, and heart physiology. What I don't like about the links is also how the stages and blood flow are separated because it becomes quite confusing and a little hard to combine the ideas together to see the whole picture of how the cardiac cycle works in terms of blood flow, heart muscles, and cycles.

This page also offers many other animations that are related to the cardiac cycle. However, I have seen better animations with other posts so I wouldn't really recommend this site compared to some of the other sites.

The animation was hard to find because so many of the animations had already been claimed on this blog. But this animation gives an accurate portrayal of the cardiac cycle. The negative things about the animation is that it does not have sound, and that the animation itself plays very quickly, to the point where you are barely able to follow, and there are no play or stop options on the page to control it. The animation is also not labeled, but there is a diagram at the bottom of the page that displays the anatomy of the heart. You can eventually figure out how blood flow through the heart works if this was the only information given to a student, but I assume it would take a while considering these negative aspects.

I actually did not like this animation at all compared to the animation that we saw in class the other day. This animation was very generic and didn't much explanation. This animation didn't any contraction of the atria or ventricles. The animation just showed arrows going throughout the body and it showed that the heart was just being filled and deflated with blood.

I found many good animations of the cardiac cycle but all them them had been used by previous posts. This particular animation is very similar to the one we saw in class, with the exception of the narration. I like this particular animation because you can adjust the speed of how fast the heart is functioning. However, what I dislike about it is that it serves as a mere diagram, and to someone who is uneducated about the functions of the heart, it is a confusing animation. If I was not informed in Thursday's lecture about the cardiac cycle, I would not really understand each individual process of the heart. It just looks like blood is flowing through, which is what it is doing, but I guess what I'm trying to say is that it is not concerned with the details of it. Also, this diagram is entailed for an audience who is familiar with the cardiac cycle. I personally like more details and information so that I am fully aware of what is going on, but I guess that is up to personal opinion.

One thing I like about this animation is that it gives other information not covered by the one in class. It explains how the sound of the heart beat is produced during the systole and diastole. For example, the first sound is caused by the closure of the AV valves and the second sound by the closure of the semilunar valves. It starts getting into more complex heart sounds that I didn’t understand too well. Other than that, this animation is not as helpful as the one in class. There is no narration but it offers a little bit of interaction on the sounds. The animation does explain the cardiac cycle to a certain extent but there is no mentioning of five distinct stages of the cycle. Putting labels telling when the stages occur could have made this animation easier to understand. Overall, this is helpful if you need another perspective on the heart.

I found this video helpful, but not entirely valuable to the cardiac cycle. I like that the video is easy to understand and explains the circulation of blood in a timely fashion. It's not very well developed and doesn't use all the terms we learned in class, however, the video gives a good overall view of the route blood takes while in the heart. Personally, I don't feel it would be beneficial to understanding the complete cardiac cycle in class, but it may help students better comprehend blood circulation in simplest terms. The graphics aren't very advanced and the voice isn't too enthusiastic, nevertheless, it does a good job at explaining the functions of the heart.

In comparison to the cardiac cycle video we watched in class, this one was not as descriptive and as informative of the cardiac cycle than the one we watched in class. This video described the cardiac cycle of the heart, but seemed to rush through the stages. The video mentions that the valves "open only one way and only when pushed on" but they never say how the blood causes these valves to open and close. Even though the video rushed through the concepts of the cardiac cycle, they did a good job in describing the cardiovascular system and how it delivers nutrients to cells. Overall, the video was not that bad, but it would be better if they paid more attention to the stages of the cardiac cycle.

Although this kinda has nothing to do with the post, i'll post it anyways because i thought it was an interesting way of how they make the blood flow models, i'll include my real video later on in the post.

http://youtube.com/watch?v=lYW16lbBWpQ

however i did find this video, which i found alot less helpful than the one shown in class, it does however give a 3d representation of the blood flow model, and at the same time both the deoxygenated and oxygenated blood flow at the same time, also in view is the back of the aorta which was not shown in the video in class.

i actually found a much better video but it's located towards the middle/end of the post in this entry, so i wasnt sure if i should put it just in case the reader wouldnt be able to find it.

http://www.nhlbi.nih.gov/health/dci/Diseases/hhw/hhw_all.html

this video is even accompanied by an explanation on what is going on in the video. very helpful! as it showed me what was moving, what direction the blood flow was in and each components name.

The animation that I have posted here is a decent animation. The thing that I did not like about it was the fact that it did not give the names of all the valves, nor did it give the entire anatomy of all the specific parts of the heart. I thought that the animation in class was much better in showing the different parts of the hearts, yet it was extremely boring. The video itself was not boring, the narrator was the one who made it boring. Being able to see how the blood physically flows through the body has given me a better understanding of how the heart works. Obviously the heart does not look the exact same as it does in the animation, but it shows much resemblance to the real thing. Overall the animation in class was extremely informative and was very helpful in understanding what happens during the cardiac cycle.
