Secretion in nephron
WebRenal urea handling. Renal urea handling is the part of renal physiology that deals with the reabsorption and secretion of urea. Movement of large amounts of urea across cell membranes is made possible by urea transporter proteins. Urea allows the kidneys to create hyperosmotic urine (urine that has more ions in it - is "more concentrated ... WebThe organs involved in the human excretory system are a pair of kidneys, a pair of ureters, the urinary bladder, and the urethra. The ultrafiltration process in the nephrons helps in the separation of urine from the blood. Glomerular filtration, reabsorption, and secretion are the three processes performed by the nephrons in order to filter blood.
