Question

Which of the following statement(s) is/are true about the heart?

• A. The left atrium receives oxygenated blood from different parts of the body while the right atrium receives deoxygenated blood from the lungs.
• B. The left ventricle pumps oxygenated blood to different body parts while the right ventricle pumps deoxygenated blood to the lungs.
• C. Left atrium transfers oxygenated blood to the right ventricle which sends it to different body parts.
• D. The right atrium receives deoxygenated blood from different parts of the body while the left ventricle pumps oxygenated blood to different parts of the body.

Answer 1

Answer: (B), (D)

The right atrium receives deoxygenated blood from different parts of the body while the left ventricle pumps oxygenated blood to different parts of the body.

The correct options are B and D.

The explanation of the correct options:

1. The right ventricle pumps oxygen-deficient blood to the lungs through the pulmonary artery.
2. The oxygenated blood passes to the body through the aorta by the left ventricle.
3. Vena cava passes the deoxygenated blood from the body to the right atrium.
4. The left ventricle pumps oxygenated blood to the body through the aorta for oxygen distribution.

The explanation of the incorrect options :

Option A:

1. The left and right atrium are the two upper chambers of the heart.
2. The left atrium receives oxygenated-rich blood from the lungs.
3. The right atrium receives deoxygenated blood from other parts of the body.

Option C:

The left atrium passes the oxygenated blood to the left ventricle, then sends it to the aorta.

Final Answer: The true statements about the heart are that the left ventricle pumps oxygenated blood to different body parts while the right ventricle pumps deoxygenated blood to the lungs and the right atrium receives deoxygenated blood from different parts of the body while the left ventricle pumps oxygenated blood to different parts of the body.
