Which of the following might trigger erythropoiesis?

B) moving to a lower altitude
C) an increased number of RBCs
D) hypoxia of EPO-producing cells

Question

Quizplus · Accepted Answer

Erythropoiesis is the process of producing red blood cells (RBCs), and it is stimulated by hypoxia (low oxygen levels) in tissues, including those of the kidney where erythropoietin (EPO), the hormone responsible for stimulating RBC production, is produced. Hypoxia in EPO-producing cells leads to increased production of EPO, which in turn stimulates the bone marrow to produce more RBCs to increase the oxygen-carrying capacity of the blood.
