Answer 2

Explanation:

1. The blood enters the heart from superior venacava and inferior vena cava into the right atrium

2. Then through the tricuspid valve the blood flows into the right ventricle.

3. The blood is forces to enter the pulmonary valve due to contraction of the ventricles.

4. Then the blood is flowed into the lungs and the alveoli present in the lungs due to osmosis the deoxgenated blood is purified into the oxygenated blood.

5. The purified blood through the pulmonary vein enters the left atrium and through the bicuspid or mitral valve the blood moves into the left ventricle.

6. Then through the ventricle contraction the blood moves into the systemic valve and through the aorta the blood is transferred to all over the body.

note:-The blood moves into ventricle because of the relaxation of the ventricles and the contraction of the atrium
