What is the resulting effect of renin being released by the kidney? A. Angiotensin II is formed B. aldosterone is released C. macula densa sends paracrine message to afferent arterioles. D. efferent arterioles are constricted
Option A. Renin catalyses the formation of angiotensin I from angioten- sinogen. ACE then converts angiotensin I to angiotensin II. Aldosterone is released from the adrenal cortex because of angiotensin II. Angiotensin II also promotes systemic vasoconstriction (now no longer simply in efferent arteriole).
