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.
Both contain an AV valve, a semilunar outflow valve, smooth and muscular parts, etc. The primary difference between the right and left sides of the heart is size. The muscle of the left ventricle is 2-3 times thicker than that of the right, although the size of the cavity itself is about the same as the right.
