Why does glomerular filtration stop during severe blood loss?
A) Glomerular capillary hydrostatic pressure drops to 45 mmHg.
B) Net filtration pressure rises above 10 mmHg.
C) Bowman's space hydrostatic pressure rises above 0 mmHg.
D) Plasma colloid osmotic pressure falls below 30 mmHg.
E) Bowman's space colloid osmotic pressure drops to 15 mmHg.

Question

Quizplus · Accepted Answer

During severe blood loss, the overall blood volume decreases, leading to a drop in glomerular capillary hydrostatic pressure, which is necessary for filtration to occur. When the pressure drops below 45 mmHg, filtration cannot occur effectively, and glomerular filtration stops. The other answer choices are not relevant to the mechanism of glomerular filtration stopping during severe blood loss.
