Transcribed image text: Consider the following: (1) Proximal convoluted tubule (2) Ascending limb of loop of Henle (3) Distal convoluted tubule (4) Descending limb of loop of Henle In which of the above structure (s) does the filtrate become MORE concentrated as it passes through? 2 4 1, 3 1, 3,4. WebThe thick descending limb is less important than the thin descending limb, so often the terms "descending limb" and "thin descending limb" are used interchangeably. Some sources simply refer to a "thin limb". In this …
WebThe descending limb of the loop of Henle is permeable to water but impermeable to solutes, due to the presence of aquaporin 1 in its tubular wall. Thus, water moves across the tubular wall into the medullary space, making the filtrate hypertonic (with a lower water potential). This is the filtrate that continues to the ascending limb. Web(A) Proximal tubule (B) Thick ascending limb of Henle’s loop (C) Distal convoluted tubule (D) Medullary collecting duct 244. When you are excreting a maximally concentrated …
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. Within the nephron of the kidney, the ascending limb of the loop of Henle is a segment of the heterogenous loop of Henle downstream of the descending limb, after the sharp bend of the loop. This part of the renal tubule is divided into a thin and thick ascending limb; the thick portion is also known as the distal straight tubule, in contrast with the distal convoluted tubule downstream.
WebOct 1, 1999 · The descending portion of these loops had a small outer diameter (thin limb) as compared to that of the ascending portion located in the outer medulla (thick limb). Figure 1 reproduces illustrations published by Henle in 1866 : note the remarkable accuracy of those hand-made drawings.

It can be divided into two parts: that in the renal medulla, and that in the renal cortex. Medullary thick ascending limb. The medullary thick ascending limb remains impermeable to water. diy frosted mason jarsWebAscending limb of the loop of Henle is less permeable to water and more permeable to sodium and chloride ions. As a result of the sodium-potassium ATPase pumps, sodium ions are extracted from the filtrate and replaced in the filtrate by potassium ions.
