Answer:
Hypotension ,Renin, Angiotensinogen,proximal side,water,ADH,collecting ducts,increase
Step-by-step explanation:
During periods of decline water levels blood volume decreases causing a decline in blood pressure.This is referred to as hypo-tension.Low blood pressure causes the kidney to increase the secretion of renin from the JG cells.The activation of angiotensinogen stimulates widespread vasoconstriction,release of ADH from the posterior pituitary as well as the adrenal cortex to release aldosterone.Aldosterone acts on the proximal side of kidney tubules to reabsorb greater amount of water from the tubular fluid.The release of ADH directly stimulates the collecting ducts of the kidney to increase water re absorption from the tubular filtrate.The net result of angiotensin 2,aldosterone and ADH cooperatively are an increase in blood pressure largely from increased blood volume.
