The impact of aldosterone on reabsorption and secretion in the late distal tubule and cortical collecting duct. Introduction: The main cell type in the late distal tubule as well as cortical collecting duct is known as theprincipal cell. These cells contain receptors for hormones like aldosterone, antidiuretic hormone, and atrial natriuretic peptide. A small number of intercalated cells are also present in these regions. Tubular reabsorption is the process of transportation of substances from tubule filtrate into the interstitial fluid, whereas secretion involves the release of harmful substances into the tubule for excretion.
