Question

When kidney of a person is damaged, he/she invariably suffers from anaemia because

  • RBCs pass through the glomerulus

  • sufficient erythropoietin is not produced

  • haemoglobin is not synthesised sufficiently

  • iron and vitamin B12 are not able to bind to haemoglobin

Answer

B.

sufficient erythropoietin is not produced

Erythropoietin is a glycoprotein produced by the kidney, which regulates red blood cell formation in the bone marrow. During kidney damage, enough erythropoietin required for adequate RBCs production is not synthesised resulting in anaemia
