Renal Tubules

Renal tubules are kidney cells that form long tubes that act as filters, allowing some substances to be reabsorbed back into the bloodstream and eliminating waste products from the body in the form of urine. The renal tubules are an important part of the body's ability to regulate water balance, electrolyte balance, and the production of hormones, such as erythropoietin and renin. They also play a role in the absorption of vitamins and minerals, as well as the production of enzymes. Dysfunction of the renal tubules can lead to a variety of medical conditions, such as chronic kidney disease (CKD), polycystic kidney disease, and nephrotic syndrome.
