Heart

The last lab practice we had, was the one of the heart. Our main goal in this lab was only about getting to know a heart better. What does it do? How does it look? Which are its parts?
In order toget the answer to all of this questions, what we need was a real heart so we would be able to look at it closely, to touch it, and to opened it.
During the lab, we used pigs’ hearts, a knife, ascalpel, robes, and gloves to keep ourselves clean.
The first thing we were supposed to do, was to describe the heart’s shape and every little details we were able to observe.
After we had thisinformation, it was time for us to get ready and opened the heart. It must follow a process so that we didn’t damage the parts of the heart. While we were doing this, we had to not only look and admire thisorgan, but to understand the function of its parts.
When the heart was already open we had to try to understand why some locations of the heart are thinner than others and understand how this affectus.
After all of this, we can get to know and understand more easily what the function of our heart is.

After that we stuck a straw into each of the arteries thatwere sticking out of the heart and we were able to understand the trajectory the blood takes once it is inside the heart: First the blood enters through the Cava vein, and then it goes straight to theright atrium and afterwards to the right ventricle. After this the blood leaves the heart through the Pulmonary artery, then the blood enters again through the Pulmonary vein and goes straight to the...
