Answer Details
The primary structure responsible for pumping blood for circulation through the mammalian circulatory system is the left ventricle. The heart has four chambers: the right and left atria, and the right and left ventricles. The right ventricle pumps blood to the lungs, while the left ventricle pumps oxygenated blood to the rest of the body through the arteries. The left ventricle is responsible for generating the force required to pump blood throughout the entire body, making it the primary pumping structure of the heart.
