what is the process of the heart

A pacemaker is a device or system that sends electrical impulses to the heart in order to set the heart rhythm. These contractions are stimulated by electrical impulses from a natural pacemaker, the sinoatrial, or S-A, node located in the muscle of the right atrium.

Heart development (also known as cardiogenesis) refers to the prenatal development of the heart.This begins with the formation of two endocardial tubes which merge to form the tubular heart, also called the primitive heart tube.The heart is the first functional organ in vertebrate embryos, and in the human, beats spontaneously by week 4 of development. It may be as simple as a straight tube, as in spiders and annelid worms, or as complex as the four-chambered double pump that is the center of the circulatory system in humans, other mammals, and birds. Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. The leaflets of the mitral and tricuspid valves are also supported by tough, fibrous strings called chordae tendineae. Angina symptoms may include chest tightness, burning, squeezing, and aching.
