Question 1
Why is sodium actively reabsorbed in the nephron?
◦ to decrease blood pressure
◦ to decrease osmolarity inside the nephron
◦ to increase passive reabsorption of water
◦ to make urine less concentrated
Question 2
Stimuli for the activation of the RAS pathway include
◦ low blood pressure in arterioles in the nephron and a decrease in fluid flow through the distal tubule.
◦ a decrease in fluid flow through the distal tubule only.
◦ low blood pressure in arterioles in the nephron only.
◦ high blood pressure in the renal artery only.
◦ low blood pressure in arterioles in the nephron, a decrease in fluid flow through the distal tubule, and high blood pressure in the renal artery.
