Mоdule 12 — Aldоsterоne-Response FаilureA dehydrаted pаtient has intact renin release, ACE activity, and angiotensin II signaling, but cells in the late distal tubule and collecting duct cannot respond to aldosterone.Predict whether renin, angiotensin II, and aldosterone levels will be low, normal, or elevated. Explain your predictions. (5 points)Predict the effects on sodium reabsorption and potassium secretion in the distal nephron. (5 points)Predict the effects on water retention, blood volume, and blood pressure. (4 points)Identify two actions of angiotensin II that can still occur despite aldosterone-receptor failure. (4 points)
