Question

why valve is present in between atria and ventricle​

Answer 1

Answer:

The heart consists of four chambers, two atria (upper chambers) and two ventricles (lower chambers). There is a valve through which blood passes before leaving each chamber of the heart. These valves are actual flaps that are located on each end of the two ventricles (lower chambers of the heart). The valves prevent the backward flow of blood.

The four heart valves include the following:

• Tricuspid valve: located between the right atrium and the right ventricle .
• Pulmonary valve: located between the right ventricle and the pulmonary artery .

• Mitral valve: located between the left atrium and the left ventricle
• Aortic valve: located between the left ventricle and the aorta
