Erythropoietin hormone which stimulates R.B.C. formation is produced by

Answer: (B) Juxtaglomerular cells of the kidney. Answer: (b) Juxtaglomerular cells of the kidney Solution: The juxtaglomerular (JG) cells of the kidney produce the peptide hormone erythropoietin, which stimulates erythropoiesis (formation of RBCs).

  1. A.The cells of bone marrow
  2. B.Juxtaglomerular cells of the kidney✓
  3. C.Alpha cells of pancreas
  4. D.The cells of rostral adenohypophysis

Correct Answer

(B) Juxtaglomerular cells of the kidney

Solution & Explanation

Answer: (b) Juxtaglomerular cells of the kidney Solution: The juxtaglomerular (JG) cells of the kidney produce the peptide hormone erythropoietin, which stimulates erythropoiesis (formation of RBCs). It is therefore produced in the kidney, not in bone marrow (the site of RBC formation itself) or the pancreas/pituitary. NCERT Reference: Chapter 19, Page 247, Line(s) 19-20 — "The juxtaglomerular cells of kidney produce a peptide hormone called erythropoietin which stimulates erythropoiesis (formation of RBC)"
