The thin ascending limb is impermeable to water; but is permeable to ions allowing for some sodium reabsorption. Na/K-ATPase is expressed at very low levels in this segment and thus this reabsorption is likely through passive diffusion. Salt moves out of the tubule and into the interstitium due to osmotic pressure created by the countercurrent system. Functionally, the parts of the ascending limb in the medulla and cortex are very similar. WebThe thick ascending limb of the nephron loop (loop of Henle) is almost impermeable to water, but reabsorbs sodium, potassium, and chloride ions from the filtrate. A) The first statement is true but the second statement is false. B) The first statement is false but the second statement is true. C) Both statements are true.

WebTrue/ False: 1. Most of the reabsorption of glomerular filtrate occurs in the proximal tubules and descending limbs of nephron loops 2. The active transport of salt in the descending limb is responsible for the increase in concentration of tubular fluid 3. In the proximal tubules, sodium is actively transported out of the filtrate, and water follows by osmosis 4.

Loop of Henle - Introduction, Function, Role - Vedantu
WebHenle's loop is a long U-shaped part of the tubule that carries urine inside each nephron of reptiles, birds, and mammals. The main function of Henle's loop is to obtain water and sodium chloride from the urine. This activity allows urine production to be more concentrated than blood, reducing the amount of water needed for survival. WebApr 7, 2024 · The primary function of Nephron is to flush out waste products which include solid waste and other excess from the blood. This blood is converted into urine, secretion … WebOct 25, 2024 · The nephron is the functional unit of the kidney. It produces concentrated urine by creating an ultrafiltrate from blood.
