Solution

erythropoietin is a hormone that produces red blood cells.

a. this hormone is produce by the kidneys so whenever ther is low oxygen in the kidneys, it acts as a signal to produce and release erythropoietin.

b. since the kidneys produce erythropoietin, therefore the production cells would be the kidney cells. more specifically the cells that are in association with the proximal convoluted tubule which are called interstitial fibroblasts. Additional small amounts are produced by liver cells and pericyte cells of the brain.

c. the target cells for erythropoietin would be the cells that produce the red blood cells, since the red blood cells are produced by the bone marrow, the target cells would be the cells of the bone marrow where erythropoietin travels and acts.

d. The erythropoietin goes and binds to it\'s receptors on the developing erythroid precursor cells in the bone marrow. these red cells in response to erythropoietin produce mature erythrocytes.
