Read the following statements carefully: (A) Juxtaglomerular cells of the kidney produce a peptide hormone called erythropoietin which stimulates erythropoiesis. (B) Atrial natriuretic factor (ANF) is secreted by the atrial wall of our heart and it increases blood pressure. (C) Secretin acts on the exocrine pancreas and stimulates secretion of water and bicarbonate ions. (D) Cholecystokinin (CCK) acts only on the gal

Step-by-step solution

Statement (A) is correct as the juxtaglomerular cells (JGA) of the kidney produce a peptide hormone called erythropoietin which stimulates the formation of RBCs (erythropoiesis). Statement (B) is incorrect because the atrial wall of our heart secretes a very important peptide hormone called atrial natriuretic factor (ANF), which decreases blood pressure. When blood pressure is increased, ANF is secreted which causes dilation of the blood vessels. Statement (C) is correct as secretin acts on the exocrine pancreas an
