00:00:00,000 --> 00:00:29,000
In this project we have used a pair of scissors, tweezers and a pig's heart.

1
00:00:29,000 --> 00:00:47,000
As you can see this is the left atrium and next to it it is the right atrium and this

2
00:00:47,000 --> 00:00:52,000
is the right ventricle and the left ventricle.

3
00:00:52,000 --> 00:00:59,000
Here we have the pulmonary artery which has two branches one for each lung and next to

4
00:00:59,000 --> 00:01:04,000
it we find the vena cava.

5
00:01:04,000 --> 00:01:14,000
What is being pointed now is the right myocardium and now you can see the tricuspid valve that

6
00:01:14,000 --> 00:01:20,000
connects the right ventricle with the vena cava.

7
00:01:20,000 --> 00:01:24,000
Now we are cutting the left side of the heart to find the mitral valve.

8
00:01:24,000 --> 00:01:28,000
This one separates the pulmonary veins from the left ventricle.

9
00:01:28,000 --> 00:01:34,000
We can observe that it is parallel to the tricuspid valve that we mentioned before.

10
00:01:34,000 --> 00:01:39,000
Also we can see the myocardium, only this time it is the left myocardium.

11
00:01:39,000 --> 00:01:44,000
It can be easily appreciated that this one is thicker than the other because the right

12
00:01:44,000 --> 00:01:49,000
myocardium pumps the blood only to the lungs while the left pumps it to the rest of the

13
00:01:49,000 --> 00:01:51,000
body.
