Describe ultrafiltration or glomerular filtration in human nephrons
Answers
Glomerular filtration is a physiological function of kidney nephrons. The ultrafiltrate, which appears in the lumen of the proximal convoluted tubule, is composed of water and solutes that can pass through the filtering membrane of the capillaries. ... In general, the glomerular filtration rate (GFR) is relatively stable.
In human kidneys
blood when goes into the bowman's capsule it goes in the name of afferent artiole having larger diameter to the efferent artiole having smaller diameter ,
due to passage of blood from higher diameter to smaller diameter, blood pressure increases tremendously
and thus all the different substances present in the blood gets sepreted out and thus the substance which remains is called glomeruler filtrate or ultrafiltrate or nephric filtrate.
