Abstract:
The discovery of four major water channels in the kidney, namely aquaporins (AQP) 1, 2, 3 and 4, has allowed a substantial increase in our understanding of renal water regulation in health and disease. This review discusses the renal aquaporin water channels in the urinary dilution and concentrating defects in cardiac failure, cirrhosis, syndrome of inappropriate hormone secretion, pregnancy, hypothyroidism, isolated glucocorticoid deficiency, isolated mineralocorticoid deficiency, primary polydipsia, acquired and genetic nephrogenic diabetes insipidus.

Renal Tubule and Collecting Duct
Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...
