They help absorb water for the body in the dital tubule and collecting duct of the kidney's nephrons. Their expression there is controled by the hormone ADH (from the posterior pituitary, controled by the Hypothalamus)

What channel proteins allow water to pass across the membrane?
Aquaporins
Aquaporins are believed to be present in red blood cells and kidney tubules but very few other cells in the body?
False
Are aquaporins in all parts of the body?
They are found on the surface of eukaryotic cells
What is the role of aquaporins in a cell membrane?
Aquaporins are protein molecules embedded in the phospholipid bilayer of some cells. They transport water across the cell membrane. A certain amount of water can cross the phospholipid bilayer of the membrane, but aquaporins considerably increase the rate of passage of water. One type of cell in which aquaporins are found is in the epithelium of the human kidney, in the distal and collecting tubules. The antidiuretic hormone (ADH) stimulates epithelial cells to incorporate aquaporins into their membranes, increasing the uptake of water from the tubule into the cells, and therefore increasing the reabsorption of water into the body. Aquaporins are also important in plant cells, facilitating the symplastic movement of water through the plant, i.e. the movement of water from cell to cell via cytoplasm.
Water may move through membrane pores constructed by transmembrane proteins called?

What role of the kidney does a dialysis machine carry out?
A dialysis machine removes wastes from the body that the kidney usually does. But not as well as the kidney. About 85% of people on dialysis die in three years without a new kidney.
