convoluted tubules

convoluted tubules

ducts within the KIDNEY nephron, whose function is to allow reabsorption of salt and water, 80% in the proximal tube and the remainder in the distal tube.

The function of aldosterone in humans is to increase sodium reabsorption from the distal convoluted tubules of kidneys as well as in cells of other tissues involved with conservation of salt, such as the colon, sweat glands, and salivary glands.
Kidney injury was examined using the modified 0-5 Jablonski grading scale under a light microscope: 0 represents normal; 1 represents occasional degeneration and necrosis of individual cells; 2 represents degenerative cells and necrosis of individual tubules; 3 represents degeneration and necrosis of all cells in adjacent proximal convoluted tubules with survival of surrounding tubules; 4 represents necrosis confined to the distal third of the proximal convoluted tubules, with a band of necrosis extending across the inner cortex; and 5 represents necrosis affecting all the three segments of the proximal convoluted tubules, as described previously [25].
