<prompt> Thick Ascending Limb of loop of Henele has which channels-Na C1- cotransporterNa - 2C1- - K cotransporterENaC channelNa - aminoacid cotransporter  <response>: Ans. is b i.e., Na - 20- - K cotransporter In the thick ascending limb, a carrier Na K 20 transporter transports one Na, one K, and two Cl- from the tubular lumen into the tubular cells. This is another example of secondary active transport. From the cells Na is actively transported to the peritubular interstitium, across the basolateral membrane, by Na K ATPase. The K diffuses back into the tubular lumen and into the interstitium via ROMK and other K channels.
