• A. A-4, B-1, C-2, D-3, E-5
• B. A-2, B-1, C-4, D-3, E-5
• C. A-4, B-1, C-2, D-3, E-6
• D. A-2, B-1, C-4, D-5, E-3

Answer 1

Answer: (D)

1. Somatostatin is secreted by delta cells at several locations in the digestive system, namely, the pyloric antrum, the duodenum and the pancreatic islets.
2. Melatonin is mainly produced by the pineal gland.
3. Aldosterone, the main mineralocorticoid hormone, is a steroid hormone produced by the zona glomerulosa of the adrenal cortex in the adrenal gland. It is essential for sodium conservation in the kidney, salivary glands, sweat glands and colon.
4. Erythropoietin, also known as hematopoietic or hemopoietin, is a glycoprotein cytokine secreted by the kidney in response to cellular hypoxia; it stimulates red blood cell production in the bone marrow.
5. hCG (Human chorionic gonadotropin) is a hormone produced by the placenta after implantation. The presence of hCG is detected in some pregnancy tests.
