Bowman's capsule

(anatomy)
A two-layered membranous sac surrounding the glomerulus and constituting the closed end of a nephron in the kidneys of all higher vertebrates.

Bowman’s Capsule

 

(named after the 19th-century English physician W. Bowman), a cuplike cul-de-sac of the uriniferous tubule of the kidneys of vertebrate animals and humans. Bowman’s capsule surrounds the glomerulus and together they form the malpighian body. The wall of Bowman’s capsule consists of an inner and outer layer, between which is a gap—the cavity of Bowman’s capsule—lined with a flat epithelium. The inner layer adheres to the glomerulus, and the outer layer becomes the beginning of the uriniferous tubule. In Bowman’s capsule, so-called primary urine is formed.

This value ranges from 40-60 mmHg and favors the movement of fluid from the capillary lumen to the Bowman's space (see Figure 3).
Bowman's space hydrostatic pressure ([P.sub.BS]), which is the pressure exerted against the outer layer of the capillary walls by fluids within Bowman's space.
The PT, which drains the glomemlar filtrate from Bowman's space, is located in the renal cortex.
As blood flows through the kidneys, approximately 20% of the plasma passes from the glomerulus into Bowman's space, forming the glomerular filtrate.
