Detailed explanation-1: -Fluids from blood in the glomerulus are ultrafiltered through several layers, resulting in what is known as the filtrate. The filtrate next moves to the renal tubule, where it is further processed to form urine. The different stages of this fluid are collectively known as the tubular fluid.

Detailed explanation-2: -This layer, the filtration membrane, allows water and small solutes to pass but blocks blood cells and large proteins. Those components remain in the bloodstream. The filtrate (the fluid that has passed through the membrane) flows from the glomerular capsule further into the nephron.

Detailed explanation-3: -Tubular fluid is the fluid in the tubules of the kidney. It starts as a renal ultrafiltrate in the glomerulus, changes composition through the nephron, and ends up as urine leaving through the ureters.

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-

Detailed explanation-5: -Filtration of the blood plasma takes place in the renal corpuscle. This is the proximal end of the nephron, which is expanded into an ovoid structure. The renal corpuscles are always found in the renal cortex.
