As blood enters the capillaries from the arterioles, blood pressure _______ and osmotic potential _______.

Question

Quizplus · Accepted Answer

As blood enters the capillaries from the arterioles, blood pressure decreases due to the increased surface area of the capillaries leading to a decrease in speed of blood flow. Meanwhile, osmotic potential increases due to the higher concentration of solutes (such as proteins) in the capillaries compared to the interstitial fluid. This causes water to move from the interstitial fluid into the capillaries, resulting in an increase in osmotic pressure. Therefore, the correct choice is B, which indicates that blood pressure decreases and osmotic potential increases.
