Which of the following might trigger erythropoiesis?
A) an increased number of RBCs
B) decreased tissue demand for oxygen
C) hypoxia of EPO-producing cells
D) moving to a lower altitude

Question

Quizplus · Accepted Answer

Erythropoiesis is the process of producing red blood cells (RBCs). It is triggered by hypoxia (low oxygen levels) in tissues, including those cells that produce erythropoietin (EPO), a hormone that stimulates the production of RBCs. Hypoxia of EPO-producing cells (choice C) would stimulate erythropoiesis to increase the oxygen-carrying capacity of the blood.
