MICROANATOMY

Detailed explanation-1: -The valves prevent the backward flow of blood. Valves are actually flaps (leaflets) that act as one-way inlets for blood coming into a ventricle and one-way outlets for blood leaving a ventricle. Normal valves have 3 flaps (leaflets), except the mitral valve. It only has 2 flaps.

Detailed explanation-2: -The valves prevent the backward flow of blood. These valves are actual flaps that are located on each end of the two ventricles (lower chambers of the heart). They act as one-way inlets of blood on one side of a ventricle and one-way outlets of blood on the other side of a ventricle.

Detailed explanation-3: -The regular opening and closing of valves prevents backflow (blood that is flowing in reverse-also called venous reflux or insufficiency). If backflow occurs, blood can begin to pool in the veins, potentially damaging them.

Detailed explanation-4: -A backflow preventer valve is designed to prevent the water in your main water supply lines from flowing in a reverse direction. The valve will distribute the sanitary water from the main supply pipes to the water lines beneath your foundation.
