A patient experiences significant blood loss from trauma, causing blood pressure to drop. The juxtaglomerular cells of the afferent arteriole respond by releasing renin into the blood. Which sequence best describes how renin restores blood pressure?

Renin acts on ADH, which causes water to be excreted in the urine, reducing blood volume Renin cleaves angiotensinogen (from the liver) to angiotensin I; ACE (from the lungs) converts it to angiotensin II, which constricts arterioles and stimulates aldosterone release from the adrenal cortex; aldosterone then increases sodium and water reabsorption, restoring blood volume and pressure Renin acts on ANP, which then promotes sodium excretion and reduces blood volume Renin produces angiotensin II, which causes vasodilation and lowers peripheral resistance
