Which one of the following statements is correct with respect to kidney function regulation?
When someone drinks lot of water, ADH release is suppressed.
Exposure to cold temperature blood flow stimulates the formation of Angiotensin II.
An increase in glomerular blood flow stimulates formation of Angiotensin II.
During summer when body loses lot of water by evaporation, the release of ADH is suppressed
As we learnt in
Vasopressin -
Vasopressin acts mainly at the kidney and stimulates resorption of water and electrolytes by the distal tubules and thereby reduces loss of water through urine (diuresis)
- wherein
Hence, it is also called as anti-diuretic hormone (ADH).
