Question

Which of the following statement(s) is (are) true about human heart?
(a) Right atrium receives oxygenated blood from lungs through pulmonary artery.
(b) Left atrium transfers oxygenated blood to left ventricle which sends it to various parts of the body.
(c) Right atrium receives deoxygenated blood through vena cava from upper and lower body.
(d) Left atrium transfers oxygenated blood to aorta which sends it to different parts of the body.

• A. (a)
• B. (a) and (d)
• C. (b) and (c)
• D. (b) and (d)

Answer 1

The Correct Option is D

Step 1: Understanding the question:
The question asks which statement(s) about the human heart are true. Let's examine each statement one by one.

Statement (a):
"Right atrium receives oxygenated blood from lungs through pulmonary artery."
This statement is incorrect. The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs for oxygenation, not oxygenated blood.

Statement (b):
"Left atrium transfers oxygenated blood to left ventricle which sends it to various parts of the body."
This statement is correct. The left atrium receives oxygenated blood from the lungs and transfers it to the left ventricle, which then pumps it to various parts of the body via the aorta.

Statement (c):
"Right atrium receives deoxygenated blood through vena cava from upper and lower body."
This statement is correct. The right atrium receives deoxygenated blood from the upper and lower body through the superior and inferior vena cava.

Statement (d):
"Left atrium transfers oxygenated blood to aorta which sends it to different parts of the body."
This statement is correct. The left atrium transfers oxygenated blood to the left ventricle, which pumps it to the body via the aorta.

Step 2: Conclusion:
The correct statements are (b) and (d). Therefore, the correct answer is (b) and (d).
