Function and Physiology of Cardiac Cycle The heart contains four chambers: left and right atria and left and right ventricle. The atria are superior to the ventricles and smaller. Atria receive blood from the veins. Ventricles receive blood from the atria and eject blood to the arteries. The ...
Other key functions of the heart include: Maintaining blood pressure Controlling the rhythm and speed of your heart rate How does the heart function? The heart pumps blood through a system of blood vessels called the circulatory system. Blood vessels are of three types: arteries, capillaries, ...

If the coronary arteries bring oxygen-rich blood to the heart chambers, the coronary sinus collects deoxygenated blood from the heart muscles and takes it to the right atria, along with the venae cavae. Heart Muscles/Cardiac Muscles The wall of the heart can be divided into three layers; oute...
