Bowman's capsule (or the Bowman capsule, capsula glomeruli, or glomerular capsule) is a cup-like sac at the beginning of the tubular component of a nephron in the mammalian kidney that performs the first step in the filtration of blood to form urine. glomerulus is enclosed in the sac. Fluids from blood in the glomerulus are collected in the Bowman's capsule (i.e., glomerular filtrate) and further processed along the nephron to form urine. This process is known as ultrafiltration.
Bowman's capsule and the glomerulus form a unit called the renal corpuscle, in which the initial process of filtration occurs. A small artery carries blood into the glomerulus, where it is filtered at high pressure through two layers of cells before the remaining blood leaves through another artery.
