O urine collecting duct
Match the structure of the nephron to its primary function.
Renal corpuscle
Proximal tubule

Distal tubule
Collecting duct
responsible for size-selective filtration of the blood
responsible for active transport and reabsorption of ions and
nutrients as well as the reabsorption of water
may or may not reabsorb sodium ions depending on the
presence or absence of the hormone aldosterone.
establishes a strong osmotic gradient allowing the
reabsorption of water, sodium ions, and chloride ions.
regulates reabsorption of water in response to the presence of
ADH & secretes urea into the interstitial fluid to maintain the
osmotic gradient of the medulla.
Important for hormonal regulation of salt and water balance

These drugs inhibit the reabsorption of Na+ and Cl- ions by the ascending limb of the loop of Henle. A side effect is that they increase urination. Why do you think this is the case?arrow_forwardAs the text noted, two-thirds of the water and solutes that the body reclaims by reabsorption in nephrons occurs in the proximal tubule. Proximal tubule cells have large numbers of mitochondria and demand a great deal of oxygen. Explain why.arrow_forward

Choose of the options: 1. reabsorption of water is always controlled by the amount of ADH 2.Some regions such as the descending loop of Henle and Proximal convoluted tubule absorb water passively without ADH regulation. 3.The concentration of interstitial fluid around the nephron does not affect passive water reabsorption. 4. In the distal convoluted tubule, water must be actively transported back into the blood stream to be reabsorbed.arrow_forward
