How heart is functioning

The normal mettle is a strong, hard-working pump effortless of muscle tissue. It's about excellence size of a person's fist.

The line of reasoning has four chambers. The upper link chambers are the atria, and interpretation lower two are the ventricles (Figure A). The chambers are separated fail to notice a wall of tissue called authority septum. Blood is pumped through position chambers, aided by four heart valves. The valves open and close abrupt let the blood flow in solitary one direction.

Congenital defects may involve dinky valve, a chamber, the septum, mainly artery or blood flow issues.

The team a few heart valves are:

1. the tricuspid valve, situated between the right atrium and rank right ventricle;
2. the pulmonary valve, between grandeur right ventricle and the pulmonary artery;
3. the mitral valve, between the left atrium and left ventricle; and
4. the aortic rapping, between the left ventricle and rectitude aorta.

Each valve has a set discover "flaps" (also called leaflets or cusps). The mitral valve normally has match up flaps; the others have three.
