Detailed explanation-1: -Liquid and solutes of the blood must pass through multiple layers to move from the glomerular capillaries into Bowman’s space to ultimately become filtrate within the nephron’s lumen. Following the GBM, filtrate must pass through the epithelial layer of Bowman’s capsule, which is composed of podocytes.

Detailed explanation-2: -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-3: -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-4: -Filtrate-The clear liquid obtained after the process of filtration is called the filtrate. Filtration – The process by which the insoluble or suspended particles of a mixture are separated from the liquid by using a porous membrane called a filter is called filtration. Important points about filtration-
