The interventricular septum is a thick, muscular wall that separates the left and right ventricles of the heart. This structure is crucial in maintaining the distinct pressures required for the proper functioning of the heart, allowing it to pump oxygenated blood to the body and deoxygenated blood to the lungs without mixing. Its integrity is essential for efficient cardiac function, as it prevents backflow and ensures that each side of the heart can work effectively during contraction.
