Homeostatic mechanisms in response to blood loss include all of the following except
A) uptake of interstitial fluid due to reduced capillary pressure.
B) inhibition of EPO secretion.
C) activation of ADH secretion.
D) activation of aldosterone secretion.
E) increased thirst and water intake.

Question

Quizplus · Accepted Answer

Inhibition of EPO secretion would not be a homeostatic mechanism in response to blood loss, as EPO (erythropoietin) stimulates the production of red blood cells, which would be needed to replace those lost due to bleeding. The other choices are all viable mechanisms: uptake of interstitial fluid would help to increase blood volume, ADH secretion would help to retain water and increase blood pressure, aldosterone secretion would promote sodium and water retention, and increased thirst and water intake would help to restore lost fluids.
