The 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 context, the thin ascending limb of loop of Henle would be included.
The descending portion of the loop of Henle is extremely permeable to water and is less permeable to ions, therefore water is easily reabsorbed here and solutes are not readily reabsorbed. The 300 mOsm/L fluid from the loop loses water to the higher concentration outside the loop and increases in tonicity until it reaches its maximum at the ...
The nephron is the minute or microscopic structural and ... (proximal straight tubule); the loop of Henle, which has two parts, the descending loop of Henle ...
Equilibration: Since the descending limb of the loop of Henle consists of very leaky epithelium, the fluid inside the descending limb becomes hyperosmolar. [citation needed] Shift: The movement of fluid through the tubules causes the hyperosmotic fluid to move further down the loop. Repeating many cycles causes fluid to be near isosmolar at the ...
The renal tubule and the renal corpuscle together comprise the nephron. [1] The thin segment is described as a U-shaped band, consisting of the two continuous parts: descending limb of loop of Henle; ascending limb of loop of Henle
They enter the medulla, and surround the loop of Henle. Whereas the peritubular capillaries surround the cortical parts of the tubules, the vasa recta go into the medulla and are closer to the loop of Henle, [1] [2] and leave to ascend to the cortex. [3] [4]
This illustration demonstrates the normal kidney physiology, including the Proximal Convoluted Tubule (PCT), Loop of Henle, and Distal Convoluted Tubule (DCT). It also includes illustrations showing where some types of diuretics act, and what they do. Renal physiology (Latin renes, "kidneys") is the study of the physiology of the kidney.
The descending vasa recta, ascending vasa recta vessels, and the loop of Henle together form the countercurrent system of the kidney. In the afferent arteriole, blood is supplied at high pressure, which promotes filtration, and in the efferent arteriole, it is at low pressure, which promotes reabsorption .
