In the thick segment (Site 2, Fig. 27.1 ), sodium and chloride ions are transported from the tubular fluid into the interstitial fluid by the three-ion co-transporter system (i.e. Na + /K + /2Cl − called NKCC2) driven by the sodium pump.

WebIn the loop of Henle, the permeability of the membrane changes. The descending limb is permeable to water, not solutes; the opposite is true for the ascending limb. Additionally, the loop of Henle invades the renal medulla, which is naturally high in salt concentration and tends to absorb water from the renal tubule and concentrate the filtrate. elys funeral directors willenhall https://arborinnbb.com

WebThe juxtaglomerular apparatus is part of the kidney nephron, next to the glomerulus. It is found between afferent arteriole and the distal convoluted tubule of the same nephron. This location is critical to its function in regulating renal blood flow and glomerular filtration rate . Function [ edit] Juxtaglomerular cells [ edit] WebThe ascending limb actively pumps sodium out of the filtrate, generating the hypertonic interstitium that drives countercurrent exchange. In passing through the ascending limb, the filtrate grows hypotonic since it has lost much of its sodium content. This hypotonic filtrate is passed to the distal convoluted tubule in the renal cortex. [1] : 72
