Question

Describe the hormones and organs associated with red blood production. Describe how red blood cell production is regulated

Answer 1

Hormones associated with red blood production:

1. Erythropoietin:

  It is an hormone which is produced by kidney it plays a major role in the production of red blood cells.

2. Thyroxine:

It is an metabolic hormone which stimulates the production of red blood cells .

Organs associated with red blood cell production:

1.Kidney:

It is an organ which is producing the hormone called erythropoietin. So this is the main organ associated with the production of red blood cells.

2.Liver:

  At the 3rd month of intrauterine life the red blood cells is produced by the liver.

3. Bone marrow:

  In the growing children and adults ,the bone marrow of bones plays a major role in the production of red blood cells.

  In some cases the red blood cells is produced in spleen and lymphoid organs this is called as extramedullary erythropoiesis.

Regulation of Red blood cells production:

  The production of red blood cells is regulated by the hormone called erythropoietin which it is produced by peritubular cells of kidney. The peritubular cells detect the oxygen content of the tissues. When the oxygen content of the kidney get reduced the kidney secretes the erythropoietin hormone to increase the production of red blood cells.
