The thin segment of the nephron loop's descending limb ________. The thin segment of the nephron loop's descending limb ________
. is easily broken and replaced often aids in the passive movement of water out of the tubule aids in the passive excretion of nitrogenous waste helps to pack a greater number of nephron loops into a smaller space
The correct answer is ''aids in the passive movement of water out of the tubule''
Explanation:
The nephron loop has a descending branch, which goes to the renal medulla, and an ascending branch, which goes back to the cortex. The nephrons of these kidneys can have loops of Henle of different dimensions. The thin segment of the loop has thin epithelial membranes, its cells are highly permeable to water, but not to solutes. The water that exits from the descending portion of the nephron loop into the medullary space is immediately reabsorbed by the peritubular capillaries, causing osmolality to increase in both the tubular fluid and the medullary interstitial fluid. The characteristics of the descending branch differ from one species to another, the normal thing is that in one way or another, the osmotic concentration of the urine that moves through it is balanced with that of the interstitial fluid.
When scientists conduct an experiment and analyze the results, the next step is to write up a report that describes the experiment and the results and submit it for publication in a scientific or medical journal that is “peer reviewed.”
