Detailed explanation-1: -Glomerular Filteration. Glomerular filtration occurs in the glomerulus where blood is filtered. Reabsorption. Around 99 per cent of the filtrate obtained is reabsorbed by the renal tubules. Secretion. The next step in urine formation is tubular secretion. Urine. 31-May-2020
Detailed explanation-2: -Tubular secretion is the final step in urine formation. This step majorly involves the removal of waste molecules and some ions such as hydrogen ions from the renal tubular cells into a collecting duct.
Detailed explanation-3: -Urine formation takes place in three steps namely, glomerular filtration, selective reabsorption and tubular secretion. In the first step, blood containing nitrogenous wastes is filtered through a tuft of capillaries called glomerulus. This is followed by selective reabsorption of glucose, amino acids etc.
Detailed explanation-4: -Urine produced in the kidneys passes through the ureters, collects in the bladder, and is then excreted through the urethra.
