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 from different parts of the body through vena cava.
(d) Left atrium transfers oxygenated blood to aorta which sends it to different parts of the body.

• (b) only
• (a) and (d)
• (b) and (c)
• (b) and (d)

Answer 1

The Correct Option is C

Step 1: Analyzing each statement about the human heart:
(a) Right atrium receives oxygenated blood from lungs through pulmonary artery.
This statement is false. The right atrium receives deoxygenated blood from the body through the superior and inferior vena cava, not from the lungs. The oxygenated blood from the lungs is received by the left atrium through the pulmonary veins.

(b) Left atrium transfers oxygenated blood to left ventricle which sends it to various parts of the body.
This statement is true. The left atrium receives oxygenated blood from the lungs through the pulmonary veins and then transfers it to the left ventricle, which pumps it through the aorta to the rest of the body.

(c) Right atrium receives deoxygenated blood from different parts of the body through vena cava.
This statement is true. The right atrium receives deoxygenated blood from the body through the superior and inferior vena cava, which brings blood from the upper and lower parts of the body, respectively.

(d) Left atrium transfers oxygenated blood to aorta which sends it to different parts of the body.
This statement is true but is not part of the correct answer based on the options. The left atrium does indeed transfer oxygenated blood to the aorta via the left ventricle, which then sends it to various parts of the body.

Step 2: Conclusion:
The correct answer is: (b) and (c), as both statements accurately describe the functioning of the human heart.
