WebThe thin limbs of the loop of Henle, which comprise the intermediate segment, connect the proximal tubule to the distal tubule and lie entirely within the renal medulla. The descending thin limb consists of at least two or three morphologically and functionally distinct subsegments and participates in transepithelial transport of NaCl, urea, and water.

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. WebThe descending loop of Henle is lined with cells containing aquaporins that allow water to pass from the filtrate into the interstitial fluid. In the thin part of the ascending loop of Henle, Na + and Cl − ions diffuse into the interstitial fluid. In the thick part, these same ions are actively transported into the interstitial fluid. tick keyboard shortcut excel

WebOverview. In the kidney, the loop of henle is the portion of the nephron that leads from the proximal convoluted tubule to the distal convoluted tubule.The loop has a hairpin bend in the renal medulla. The main function of this structure is to reabsorb water and ions from the urine.To do this, it uses a countercurrent multiplier mechanism in the medulla. It is … WebStudy with Quizlet and memorize flashcards containing terms like The renal system does not play a direct role in regulating which of the following? A. Blood pH B. Blood pressure C.

Connecting … WebSchematic representation of the transport mechanisms in the thick ascending limb of the loop of Henle. The Na-K-ATPase pump in the basolateral (peritubular) membrane pumps Na out of, and K into, the cell. This creates a low intracellular Na concentration, which drives the electroneutral Na-K-2Cl cotransporter (NKCC2) at the apical membrane. the long night hbo series
