25. The Urinary System

Which of the following is NOT a purpose of tubular reabsorption?

Which of the following solutes are primarily reabsorbed by primary active transport?

In the proximal tubule, _________ ions are pumped out of the tubule via ____________ transport. This creates an ____________ gradient, causing water to be reabsorbed through _______________.

In the proximal tubule, _________ ions are pumped out of the tubule via ____________ transport. This creates an ____________ gradient, causing water to be reabsorbed through _______________.

Mark the following statements as true or false. If a statement is false, correct it to make a true statement.

d. ADH triggers water reabsorption from the nephron loop.

Explain how the peritubular capillaries are adapted for receiving reabsorbed substances.

Describe what is involved in active and passive tubular reabsorption.

Tubular reabsorption

a. Of glucose and many other substances is a T_m - limited active transport process

b. Of chloride is always linked to the passive transport of Na⁺

c. Is the movement of substances from the blood into the nephron

d. Of sodium occurs only in the proximal tubule
