Renal transport refers to the process by which the kidneys filter and reabsorb substances from the blood, and then excrete waste products in the form of urine. This complex system of transport involves various mechanisms such as active transport, passive transport, and facilitated diffusion to maintain the body's fluid balance, electrolyte levels, and pH regulation. Research in this area focuses on understanding the molecular mechanisms and regulation of renal transport processes, as well as the implications for kidney function and disease states such as hypertension, diabetes, and kidney failure. Studies in renal transport also aim to develop new therapeutic strategies for kidney disorders and related conditions.
