Human Kidney-Bowman's Capsule

This Picture is showing a cross section of cortex region of the kidney. Picture is focused into a glomerulus, located within the Bowman's Capsule.Vascular Pole, Distal Convoluted tubule(small circular region), Macula Densa(cells lining the DC) are seen on the right side. At the same time proximal convoluted tubule(circular region),Urinary pole are seen on the left side of the picture. Efferent arteriole and Afferent Arteriole, which are not seen, joins the glomerulus in the vascular pole region.

The Bowman's 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. A 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.
