Urine formation involves three main processes namely, glomerular filtration, reabsorption and secretion, that takes place in different parts of the nephron. The first step in urine formation is the filtration of blood, which is carried out by the glomerulus and …
Urine Formation - Mechanism of Urine Formation and Osmoregulation …
The mechanism of urine formation involves the following steps: Glomerular Filteration. Glomerular filtration occurs in the glomerulus where blood is filtered. This process occurs across the three layers- the epithelium of Bowman’s capsule, the endothelium of glomerular blood vessels, and a membrane between these two layers.
Describe the mechanism of urine formation. - BYJU'S
Urine formation occurs in 4 steps Ultrafiltration, reabsorption, tubular secretion, and concentration of urine. Ultrafiltration: Blood enters through the glomerulus under pressure, and most of the small solutes and water get filtered.

Sep 27, 2019 · The kidneys have built-in mechanisms for the regulation of glomerular filtration rate. One such efficient mechanism is carried out by juxta glomerular apparatus (JGA). JGA is a special sensitive region formed by cellular modifications in the distal convoluted tubule and the afferent arteriole at the location of their contact. A fall in GFR can ...
