Answer:
collecting duct
Explanation:
The collecting duct is part of nephrons and has mainly two types of cells. These are called principal cells and intercalated cells. The principal cells of collecting duct have receptors for ADH and aldosterone. The function of the anti-diuretic hormone (ADH) is to reduce the fluid loss from the body when blood volume and blood pressure fall and the person experiences dehydration. In response to ADH, transcytosis of water in collecting duct is stimulated. This results in the absorption of most of the water from the filtrate and formation of concentrated urine.
