Questions: Learning: Chapter 25 Section 3.5 QUESTION 2 Which answer choice refers to the force of blood against the walls of the vascular system? I DON'T KNOW YET Constriction increases pressure (T/F) Net filtration pressure (NFP) Capillary hydrostatic pressure (HPc) Glomerular hydrostatic pressure (GPc) ANSWER

The answer is: Capillary hydrostatic pressure (HPc)

Explanation for each option:

1. Constriction increases pressure (T/F): This is a statement rather than a term referring to the force of blood against the walls of the vascular system. It is true that constriction of blood vessels increases pressure, but it does not directly answer the question.

2. Net filtration pressure (NFP): This term refers to the balance of pressures that determine the movement of fluid into or out of capillaries, not specifically the force of blood against the walls of the vascular system.

3. Capillary hydrostatic pressure (HPc): This is the correct term. It refers to the force exerted by the blood against the walls of the capillaries, which is a part of the vascular system.

4. Glomerular hydrostatic pressure (GPc): This term refers specifically to the pressure within the glomerular capillaries in the kidneys, not the general force of blood against the walls of the entire vascular system.

Summary: The correct answer is Capillary hydrostatic pressure (HPc), as it directly refers to the force of blood against the walls of the vascular system.
