Question

10) The speed of blood:

a) It decreases from the aorta to the vena cava
b) It decreases from the aorta to the capillaries and then increases.
c) It is the same in all the vascular tree
d) Increases from the aorta to the capillaries

Answer 1

#1 or A is your answer

Answer 2

A

Step-by-step explanation:

After the blood has passed through the capillary beds, it enters the venules, veins, and finally the two main venae cavae (singular, vena cava) that take blood back to the heart. The flow rate increases again, but is still much slower than the initial rate in the aorta.
