Heart dissection

1. The most surprising thing I found about the heart was that the atria appeared as flaps did not appear as they would on paper.

2. The reason the atria and the ventricles are so different in structure is that the ventricles were thick and hard to cut through do to the amount of blood pumping through and the atria were flappy, pruny, and seemed more like a storage than atrium. The atria must deliver blood to the ventricles while the ventricles deliver blood to arteries to go outside the heart.

3. The left ventricle is larger than the right ventricle because the left ventricle mudt pump to the entire body while the right ventricle only has to pump it to the lungs.

4. The function is of the valves is to make sure blood flow goes through and does not go back. The chordae tendinae helps keeps the valves intact. The importance of the valves is very high as they prevent reverse blood flow which can damage our bodies
