The Atrial wall of the human heart secretes a very important peptide hormone. What is the name of that hormone?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. ANF.
| Atrial natriuretic peptide (ANP) or atrial natriuretic factor (ANF) is a natriuretic peptide secreted and released by the cardiac muscle cells. ANF acts on the kidney to increase sodium excretion and GFR, to antagonize renal vasoconstriction, and to inhibit renin secretion. | |
|
GIP |
GIP hormone secreted by cells of the intestinal mucosa that blocks the secretion of hydrochloric acid into the stomach.GIP has an inhibitory action on gastric glands and thus inhibits gastric secretion. |
|
CCK |
Cholecystokinin (CCK) formerly called pancreozymins is a digestive hormone. The most recognized functions of this hormone are indigestion and appetite. CCK stimulates the secretion of pancreatic enzymes and bile by the pancreas and gallbladder respectively. |
| ADH | Vasopressin is also called ADH. Antidiuretic hormone (ADH), produced in the hypothalamus of the brain and released into the bloodstream from the pituitary gland, enhances fluid retention by making the kidneys reabsorb more water. |
