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 right ventricle only has to get blood into the lungs, which are just next door. The left ventricle is what pumps oxygenated blood into every other part of the body.) That's why you may feel your heartbeat more strongly on the left side than the right. But that doesn't mean your heart is on the left. That's where your left lung goes. A small number of people have a condition called dextrocardia, in which the heart is flipped and actually tilts to the right. Sometimes this mirror-image anatomy extends to all their organs, an even rarer condition called situs inversus.
