Question 9 • Biology

Which statement explains blood pressure?

Answer
A
Blood pressure is highest in the veins farthest away from the heart.
B
Blood pressure is highest in the arteries near the heart.
C
Blood pressure is highest in the veins near the heart.
D
Blood pressure is highest in the arteries farthest away from the heart.

Explanation

Blood pressure is greatest in the arteries closest to the heart because the heart’s pumping force is transmitted directly into them. As blood travels through smaller arteries and then into capillaries and veins, pressure decreases. Therefore, “Blood pressure is highest in the arteries near the heart” is correct.
