Question

Which statements describe the movement of blood through the heart? Check all that apply.

1. Blood from the veins enters the ventricles.

2. Atria and ventricles contract at the same time.

3. Atria push blood into the ventricles.

4. Valves allow for two-way blood flow.

5. Ventricles push blood out of the heart.

Answer 1

3 and 5 are correct statements

Answer 2

Option (3) and (5) is Right Answer

Explanation:

• Atria and ventricles contract at the same time and Ventricles push blood out of the heart
• The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle through the tricuspid valve  
• The right ventricle pumps the oxygen-poor blood to the lungs through the pneumonic valve
• Blood from right chamber enters right ventricle and pulmonary arteries convey deoxygenated blood from right ventricle to lungs for oxygenation
• Two pulmonary veins originate from every lung and pass O2-rich blood to left chamber
• Blood enters left ventricle from the left atrium
