Answer 1

Answer:

1.The heart has four chambers: two atria and two ventricles.

4.*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.

ventricle.

*Aortic valve.

Valve:-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.

1]The heart has four chambers: two atria and two ventricles. The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle. The right ventricle pumps the oxygen-poor blood to the lungs. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.

2]The inferior and superior vena cava bring oxygen-poor blood from the body into the right atrium. The pulmonary artery carries oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream. The pulmonary veins bring oxygen-rich blood to the left atrium.
