- a)Name the two factors that trigger the release of ADH (vasopressin). b) What happens to plasma osmolarity when there is excessive water loss through sweating and it is not replaced? c) Describe the renal regulation of potassium, where is K+, what is the hormone that is responsible for the secretion of K+, the name of the cells, and the location in the nephron where the fine-tuning of K+ occurs.arrow_forwardDuring a state of low blood volume and decreased extracellular sodium level (as in cardiac failure), which one of the following occurs? 1) B. Aldosterone is produced by the kidneys, leading to the release of renin, which increases kidney reabsorption of sodium. 2) D. Antidiuretic hormone produced by the kidneys stimulates the production of aldosterone by the adrenal gland, which increases reabsorption of sodium and water retention. 3) A. Renin is produced by the kidneys and is converted to angiotensin, which induces the secretion of aldosterone by the adrenal gland, which in turn increases reabsorption of sodium and retention of water. 4) C. Renin is produced by the adrenal glands, leading to vasoconstriction and production of antidiuretic hormone by the pituitary gland, which increases fluid volume by causing water retention. no references, just homeworkarrow_forward56.
