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 pumps the blood to the rest of your body through the aorta. For the heart to work well, your blood must flow in only one direction. Your heart's valves make this possible. Both of your heart's ventricles have an in (inlet) valve from the atria and an out (outlet) valve leading to your arteries.
