Answer:
The correct answer is option D: It causes secretion of renin from J.G. cells.
ADH (antidiuretic hormone), also known as vasopressin, is a hormone produced by the hypothalamus and released by the posterior pituitary gland. It plays a crucial role in regulating water balance in the body by acting on the kidneys. However, ADH is not directly involved in the secretion of renin from J.G. (juxtaglomerular) cells.
Functions of ADH:
1. Facilitates water and electrolyte reabsorption: ADH facilitates the reabsorption of water and electrolytes from the distal parts of the renal tubules and the collecting ducts. It does so by increasing the permeability of these tubules to water, allowing more water to be reabsorbed back into the bloodstream. This helps to concentrate urine and conserve water in the body.
2. Affects kidney function through vasoconstriction: ADH also has vasoconstrictor effects on blood vessels. It causes the constriction of blood vessels, including those in the kidneys. This vasoconstriction helps to increase blood pressure and maintain an adequate glomerular blood flow, ensuring proper filtration in the kidneys.
3. Causes an increase in blood pressure: By constricting blood vessels, ADH causes an increase in blood pressure. This increase in blood pressure helps to maintain an adequate glomerular blood flow, ensuring proper kidney function.
4. Stimulates the release of aldosterone: ADH stimulates the release of aldosterone from the adrenal glands. Aldosterone is a hormone that acts on the kidneys to increase the reabsorption of sodium and water. This further helps to regulate water balance in the body.
5. Stimulates thirst: ADH also plays a role in stimulating thirst. When ADH levels increase, it signals the brain to increase fluid intake, helping to maintain water balance in the body.
Conclusion:
While ADH is involved in various functions related to water balance and kidney function, it does not directly cause the secretion of renin from J.G. cells. Renin secretion is primarily regulated by the renin-angiotensin-aldosterone system and other factors, such as blood pressure and sodium levels.
