Webfunctional unit of the mammalian kidney. • Kidneys, the excretory organs of vertebrates, function in both excretion and osmoregulation. • The mammalian excretory system centers on. paired kidneys, which are also the principal site of. water balance and salt regulation. • Each kidney is supplied with blood by a renal. WebIn the loop of Henle, the filtrate continues to exchange solutes and water with the renal medulla and the peritubular capillary network. Water is also reabsorbed during this step. Then, additional solutes and wastes are secreted into the kidney tubules during tubular secretion, which is, in essence, the opposite process to tubular reabsorption.

WebThe Loop of Henle aids in water conservation through its duct within the renal tube. This helps with water conservation with countercurrent exchanges. It dilutes the urine as it moves throughout the Loop of Henle and then concentrates urine in the distal tubules and collecting ducts. The descending Loop of Henle is initially impermeable to sodium … WebAbstract The fluid entering the loop of Henle is isotonic to plasma, but, after traversing the loop, fluid entering the distal tubule is hypotonic to plasma, i.e. the tubular fluid has been diluted during its passage around the loop of Henle.
