What could happen if the AV valves were to evert into theatria?
What could happen if the AV valves were to evert into the
atria?
The heart is the organ that pumps blood in the body. It pumps oxygenated blood, received from the lungs, to all cells and tissues. It pumps deoxygenated blood, received from all cells and tissues, to the lungs for oxygenation. This type of circulation is known as double circulation.
The heart is made up of 4 chambers: two upper atria and two lower ventricles. The heart also contains valves that ensure blood flow is unidirectional. There are two types of valves in the heart, atrioventricular (AV) valves and semilunar (SL) valves. Each valve controls blood flow from a specific part of the heart.
The structure of the valve is such that blood pressure causes the valve to open, which allows blood to flow to the next structure, after which the valves shutter back and close. This prevents blood from flowing back and ensures unidirectional flow.
