WebAs filtrate passes through the loop of Henle, salt is reabsorbed and concentrated in the interstitial fluid of the medulla. This high solute concentration in the medulla enables nephrons to a. excrete the maximum amount of salt. b. neutralize toxins that might be found in the kidney. c. excrete a large amount of water. d. reabsorb water from the filtrate very … 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.

Understanding dynamics of NaCl reabsorption from loops of Henle, and cellular and physiological consequences, requires a clear understanding of the structural … WebEnter the renal medulla and the loop of Henle. The medulla is very poorly drained (more on that later) and so it is possible to set up a large osmotic gradient in the medulla and keep it there (anywhere else and the blood would wash the gradient away). The other part of the problem is how to create a large osmotic gradient.

WebMost water reabsorption occurs in the PCT and the rest occurs in the descending loop of Henle. Osmolarity (usually used) is the concentration per liter. Osmolality (rarely used) is the concentration per kilogram. They are just different units and different numbers … The renal medulla is the innermost part of the kidney. The renal medulla is split up into a number of sections, known as the renal pyramids. Blood enters into the kidney via the renal artery, which then splits up to form the segmental arteries which then branch to form interlobar arteries. The interlobar arteries each in turn branch into arcuate arteries, which in turn branch to form interlobular arteries, and these finally reach the glomeruli. At the glomerulus the blood reaches …

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.
