WebFormation of urine. Topic: Excretory System. The formation of urine takes place in the nephron, which is the structural and fundamental unit of the kidney. It occurs through three steps: glomerular filtration, tubular reabsorption, and tubular secretion. The first step of the formation of the urine is glomerular filtration in the glomerules. WebKidney Tubule Absorption. In contrast, the renal tubular reabsorption is the process where the removed water and solutes from the glomerular capillaries transport into the blood circulatory system to maintain homeostasis, which mostly occurs in the proximal tubule by osmotic pressure and active transport of the tubular epithelial cells.
