Does the heart have four chambers and divided into a right and left side by a musclar wall called the septum?

Yes, the heart has four chambers: two upper chambers called atria and two lower chambers called ventricles. It is divided into a right side and a left side by a muscular wall known as the septum. The right side pumps deoxygenated blood to the lungs, while the left side pumps oxygenated blood to the rest of the body. This division is essential for the efficient circulation of blood.
