Which statement about angiotensin is true? $a .$ It is secreted by the kidney when the glomerular filtration rate falls. $b$. It is released by the posterior pituitary when blood pressure falls. $c .$ It stimulates thirst. $d .$ It increases the permeability of the collecting ducts to water. e. It decreases glomerular filtration rate when blood pressure rises.
Angiotensin II is a peptide hormone that helps - conserve blood volume by stimulating vasopressin release - increase blood pressure by increasing cardiac output and peripheral resistance - All three processes are under angiotensin control. - cause Na+ reabsorption by stimulating aldosterone release
Adi S.
Complete each statement by using the appropriate word or phrase from the list. A decrease in blood pressure is sensed by the macula densa, resulting in stimulation of JG cells. The JG cells respond by secreting renin into the plasma, which eventually encounters angiotensinogen from the liver. Angiotensinogen is converted to angiotensin I as a result of the action of the enzyme renin. Now 10 amino acids long, angiotensin I continues to circulate until being acted upon by ACE. ACE from the lungs finalizes the conversion of angiotensin I to angiotensin II. Now in an active form, angiotensin II binds to target cells in three distinct areas of the body. The resulting actions of angiotensin II cause the release of ADH from the hypothalamus, release of aldosterone from the renal cortex, and widespread vasoconstriction.
