The heart has an electrical system that synchronizes its contraction efficiently.
The upper chambers, the atria, must first contract to fill the ventricles in the lower part of the heart. These, in turn, will compress and, in an inescapable upward movement, spill their contents into the large vessels at the top.
Tricuspid valves include the pulmonary and the aortic valves. Each has 3 cusps that fit onto a fibrous ring in the cardiac skeleton. These valves separate the pulmonary artery from the right ventricle and the aorta from the left ventricle.
The 2 valves that separate the ventricles from the atria are called atrioventricular valves. The tricuspid valve is located on the right side and the mitral valve is on the left.
This site is intended to provide information and make cardiology comprehensible for all patients; it is not a substitute for a doctor. It does, however, enable a better understanding of how the heart works, the many heart diseases that exist, the tests required to reach a diagnosis, and the drugs and other methods used to treat them.
