In this project we have used a pair of scissors, tweezers and a pig's heart. 00:00:00
As you can see this is the left atrium and next to it it is the right atrium and this 00:00:29
is the right ventricle and the left ventricle. 00:00:47
Here we have the pulmonary artery which has two branches one for each lung and next to 00:00:52
it we find the vena cava. 00:00:59
What is being pointed now is the right myocardium and now you can see the tricuspid valve that 00:01:04
connects the right ventricle with the vena cava. 00:01:14
Now we are cutting the left side of the heart to find the mitral valve. 00:01:20
This one separates the pulmonary veins from the left ventricle. 00:01:24
We can observe that it is parallel to the tricuspid valve that we mentioned before. 00:01:28
Also we can see the myocardium, only this time it is the left myocardium. 00:01:34
It can be easily appreciated that this one is thicker than the other because the right 00:01:39
myocardium pumps the blood only to the lungs while the left pumps it to the rest of the 00:01:44
body. 00:01:49
