Question

4. Explain the location and functions of various valves present in the heart and blood vessels.​

Answer 1

Answer:

There is a valve through which blood passes before leaving each chamber of the heart. 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).

Answer 2

Answer:

HEART VAVES

The mitral valve and tricuspid valve are located between the atria (upper heart chambers) and the ventricles (lower heart chambers). The aortic valve and pulmonic valve are located between the ventricles and the major blood vessels leaving the heart

BLOOD VESSEL VAVES

There are five types of blood vessels: the arteries, which carry the blood away from the heart; the arterioles; the capillaries, where the exchange of water and chemicals between the blood and the tissues occurs; the venules; and the veins, which carry blood from the capillaries back towards the heart.
