-What happens as blood is transported from the aorta to the capillaries?
A) Pressure increases

Question

Quizplus · Accepted Answer

As blood moves from the aorta to the capillaries, the total cross-sectional area of the vessels increases, leading to an increase in resistance. This is because the numerous small capillaries present a greater area of friction to the flow of blood, compared to the singular, large aorta.
