Which of the following correctly traces blood flow from the renal artery into the renal cortex?

A. Extrinsic controls will reduce blood plasma volume while intrinsic controls will increase blood plasma volumes: This is too simplistic. Both can influence fluid volume, but their primary goals differ.
B. Intrinsic controls raise blood pressure while extrinsic controls lower blood pressure: Intrinsic controls maintain GFR, not blood pressure; extrinsic controls (like RAAS and sympathetic input) raise BP.
C. Extrinsic and intrinsic controls work in nearly opposite ways: They serve different purposes rather than being true opposites.
D. Extrinsic controls have the greatest effect on systemic blood pressure while intrinsic controls have a greater effect on GFR: Intrinsic (renal autoregulation) maintains a constant GFR; extrinsic controls (like sympathetic nervous system and RAAS) maintain systemic blood pressure, especially during stress or blood loss.

A. Hydrostatic pressure of capillary blood: This pushes water out of capillaries into the interstitial space-it's the main driver of filtration at the arterial end of capillaries.
B. Osmotic pressure of plasma proteins: This pulls water back into capillaries, opposing outward flow.
C. Hydrostatic pressure of interstitial fluid: This would oppose outward filtration if significant, but it's usually low.
D. Intracellular hydrostatic pressure: This is not relevant to capillary filtration, which occurs between plasma and interstitial fluid.
