Which row about the circulatory system is correct?
▶️ Answer/Explanation
Ans: A
The correct row describes the systemic circulation, where oxygenated blood is pumped from the heart to the body (via the aorta) and deoxygenated blood returns to the heart (via the vena cava). This matches option A. The other rows misrepresent key details (e.g., pulmonary circulation involves the pulmonary artery carrying deoxygenated blood to the lungs, not oxygenated blood).
Which statement describes the circulation of blood in the human body?
A) Blood is pumped away from the heart by the atria.
B) Blood is pumped away from the heart through arteries.
C) Blood is pumped away from the heart through veins.
D) Blood is pumped to the heart through capillaries.
▶️ Answer/Explanation
Ans: B
In the human circulatory system, arteries carry oxygenated blood away from the heart, while veins return deoxygenated blood back to the heart. The atria (A) receive blood, not pump it away, and capillaries (D) facilitate exchange, not transport to the heart.
Since arteries are the vessels responsible for transporting blood away from the heart, the correct answer is B (Blood is pumped away from the heart through arteries).
