• A. p-1, q-3, r-2, s-4
• B. p-3, q-4, r-1, s-2
• C. p-1, q-2, r-3, s-4
• D. p-2, q-4, r-1, s-3

Answer 1

The correct option is D p-2, q-4, r-1, s-3

The C cells of the thyroid gland are also called parafollicular cells. They are responsible for secreting calcitonin.

Increased stomach pH or an ingestion of proteins triggers the G cells of the stomach to secrete gastrin. Gastrin acts on gastric glands and stimulates the secretion of hydrochloric acid and pepsinogen.

The entry of gastric acid inside the intestine triggers S cells of the duodenum to release secretin. Secretin acts on the exocrine part of the pancreas and stimulates the secretion of water and bicarbonate ions.

Erythropoietin is a peptide hormone secreted by the juxtaglomerular cells of the kidney. It stimulates the process of RBC synthesis or erythropoiesis.
