APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Fluids comprising excess water, salt and metabolic waste products are extracted from the blood as it enters the Bowman’s capsule in the nephrons. This fluid in the Bowman’s capsule is called glomerular filtrate. It is similar to blood plasma except that it has almost no protein.

Detailed explanation-2: -As a result, the filtrate leaving the Bowman’s capsule is very similar to blood plasma (filtrate or glomerular filtrate is composed of blood plasma minus plasma protein i.e. it contains all the components of blood plasma except the proteins) in composition as it passes into the proximal convoluted tubule.

Detailed explanation-3: -Fluid exchange in the Bowman’s capsule is governed by the same Starling’s forces operating in the glomerulus. That is, the fluid there also exerts a hydrostatic pressure and it, in effect, opposes the hydrostatic pressure coming from the glomerulus.
