In summary, the loop of Henle is surrounded by tissue fluid which has a ... marchetti srl citta della pieveThe descending loop of Henle receives isotonic (300 mOsm/L) fluid from the proximal convoluted tubule (PCT). The fluid is isotonic because as ions are reabsorbed by the gradient time system, water is also reabsorbed maintaining the osmolarity of the fluid in the PCT. Substances reabsorbed in the PCT include urea, water, potassium, sodium, chloride, glucose, amino acids, lactate, phosphate, and bicarbonate. Since water is also reabsorbed the volume of fluid in the loop of He… marchetti stephaneWeb2 Mar 2024 · The thick ascending limb (TAL) of the loop of Henle is principally responsible for sodium and chloride ion reabsorption from the glomerular filtrate.
