Question 7 • 24 - 25 CR - Biology B (0411KB)

Which statement explains blood pressure?

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

Explanation

Blood pressure is highest in the arteries closest to the heart because the heart’s contractions push blood directly into them. As blood travels through the circulation, pressure falls due to resistance in the blood vessels, so it is not highest in veins or in arteries far from the heart. The correct statement is that blood pressure is highest in the arteries near the heart.
