Septum

What is Septum?

The septum is the thick muscular partition that divides the heart into a right side and a left side. Because it is complete in a healthy heart, deoxygenated blood returning from the body on the right side never mixes with oxygenated blood returning from the lungs on the left side, so blood delivered to the body tissues carries the maximum possible amount of oxygen.

This definition is part of the Transport in Humans chapter in Cambridge O Level Biology.
