Question

What is the function of the septum separating the left and right ventricles?

Answer 1

It separates oxygenated and unoxygenated blood from mixing during the contraction cycle.  Additionally, it houses the conducting fibers that transmit the contraction impulse to the muscles in the walls of the heart.

Answer 2

The septum separates the right and left sides of the heart and prevents blood from flowing from the right to the left ventricle or vice versa during contraction. This helps to prevent the deoxygenated blood in the right ventricle mixing with the oxygenated blood in the left ventricle. It also helps maintain the shape and rigidity of the heart and provides strength to the walls of the heart.

Answer 3

To keep the oxygenated blood in the left ventricle, separate from the deoxygenated blood in the right ventricle.  If they mix, then the body can not receive the oxygen it needs.
