What is Vitamin C needed for in the human body? One of the role of vitamin C is to play a role in making the protein, collagen. Collagen is found in various places such as the connective tissue (helps hold joints togeth â¦ er for example).
There are a couple of primary differences between the atria and ventricles. The heart has four chambers. Atria make up the top chambers of the heart whereas ventricles make up the bottom chambers. This means that there are atrium and ventricle on both, right and left sides of the heart. The right part of the heart receives unoxygenized (impure) blood and sends it from ventricles to the atria.
The left ventricle receives blood from the left atrium of the heart via the relaxation of the mitral valve. When it contracts, it pushes the blood volume through the aortic valve and into the aorta. In comparison with the right ventricle, the left is both shorter in length and is transversely circular in a concave manner.
