Question

write the funtion of the following:
d) heart valves​

Answer 1

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

Answer 2

Answer:

The heart has 4 chambers, 2 upper chambers (atria) and 2 lower chambers (ventricles). Blood passes through a valve before leaving each chamber of the heart. 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. The 4 heart valves are:

Tricuspid valve. This valve is located between the right atrium and the right ventricle.

Pulmonary valve. The pulmonary valve is located between the right ventricle and the pulmonary artery.

Mitral valve. This valve is located between the left atrium and the left ventricle. It has only 2 leaflets.

Aortic valve. The aortic valve is located between the left ventricle and the aorta.
