Answer 1

Answer:

1. tricuspid valve- between the right atrium and the left ventricle.

2. pulmonary valve- between the right ventricle and the pulmonary artery.

3. mitral valve- between the left atrium and the left ventricle.

4. aortic valve- between the left ventricle and the aorta.

Explanation:

FUNCTIONS- 1. (Tricuspid valve- 3 cusps) Opens to allow blood flow from the right atrium to the right ventricle. Prevents backflow of blood from the right ventricle to the right atrium.

2. (Pulmonary valve- 2 leaflets) Opens to allow blood to be pumped from the right ventricle to the lungs through the pulmonary artery ( where it receives oxygen) Prevents the backflow of blood from the pulmonary artery to the right ventricle.

3. (Mitral valve- 2 leaflets) Opens to allow blood to flow from the lungs to the left atrium. Prevents the backflow of blood from the left ventricle to the left atrium.

4. (Aortic valve- 3 leaflets)Opens to allow blood to leave the heart from the left ventricle through the aorta and the body. Prevents the backflow of blood from the aorta to the left ventricle.
