Hello, we are Barbara, Naiara and Estela and we are going to present the parts of the heart.

1
00:00:07,000 --> 00:00:13,000
On the first video we can see that the tweezers are pointing first of all to the left artium.

2
00:00:13,000 --> 00:00:17,000
Then we are pointing to the right artium.

3
00:00:17,000 --> 00:00:21,000
Then we are pointing to the left ventricle and the right ventricle of the heart so we

4
00:00:21,000 --> 00:00:25,000
can distinguish one side from the other.

5
00:00:25,000 --> 00:00:29,000
At this time of the video we are putting inside the heart the tweezers first of all in the

6
00:00:29,000 --> 00:00:38,000
pulmonary artery and then into the aorta artery.

7
00:00:38,000 --> 00:00:48,000
Here we are opening the heart and there is the tricuspid pulp.

8
00:00:48,000 --> 00:00:55,000
Then we open the other side of the heart to see the mitral or vicuspid pulp of the heart.

9
00:00:55,000 --> 00:01:03,000
The materials that we need are a plier, scissors, tweezers and of course the heart.
