===Distal convoluted tubule===
The [[distal convoluted tubule]] has a different structure and function to that of the proximal convoluted tubule. Cells lining the tubule have numerous [[mitochondria]] to produce enough energy ([[adenosine triphosphate|ATP]]) for [[active transport]] to take place. Much of the ion transport taking place in the distal convoluted tubule is regulated by the [[endocrine system]]. In the presence of [[parathyroid hormone]], the distal convoluted tubule reabsorbs more calcium and secretes more phosphate. When [[aldosterone]] is present, more sodium is reabsorbed and more potassium secreted. Ammonia is also absorbed during the selective reabsorption. [[Atrial natriuretic peptide]] causes the distal convoluted tubule to secrete more sodium.
