What is Net filtration pressure?

NET FILTRATION PRESSURE (NFP) is the total pressure that promotes filtration. To calculate NFP, we subtract the forces that oppose filtration from the GBHP. NFP=GBHP-(CHP+BCOP) A normal NFP (using the figures mentioned) would be: NFP=55-(15+30)=55-45=10mm Hg.

What substances are excreted in the urine?

The normal chemical composition of urine is mainly water content, but it also includes nitrogenous molecules, such as urea, as well as creatinine and other metabolic waste components.

Which substances are not filtered through the kidneys?

Filterable blood components include water, nitrogenous waste, and nutrients that will be transferred into the glomerulus to form the glomerular filtrate. Non-filterable blood components include blood cells, albumins, and platelets, that will leave the glomerulus through the efferent arteriole.

What happens if waste products are not removed from the body?
