    The heart in the primary motive force for driving blood through the arterial vessels, in the human body, the heart is made up of four separate chambers , two chambers function as a 'right heart' and two function as a 'left heart'. The muscular walls of the chambers (myocardium) apply force to the blood inside so forcing the blood to move out of the chambers. The two chambers at the top of the heart are called the atria( singular they are called the atrium), the muscular walls of the atria are relatively thin. Attached to each atrium is an ear like appendage called an auricle, auricles of the atria tend to have somewhat thicker walls. The two chambers at the bottom of the heart are called ventricles, the right ventricle has a somewhat semilunar cross section, since it is wrapped around one side of the left ventricle, the left ventricle is a cylinder shape with relatively thick wall. Down the middle of the heart is a interatrial septum which separates the two atria. Between the ventricles is a wall of tissue which separates the left and right ventricles it is called the interventricular septum.
