Explanation:
Detailed explanation-1: -The entire outer surface of each individual nephron and collecting duct is coated by a basement membrane, a thin sheet of extracellular matrix composed primarily of laminin, collagen IV, entactin/nidogen, and sulfated proteoglycans.
Detailed explanation-2: -Each nephron in your kidneys has a microscopic filter, called a glomerulus that is constantly filtering your blood. Blood that is about to be filtered enters a glomerulus, which is a tuft of blood capillaries (the smallest of blood vessels).
Detailed explanation-3: -GEnC fenestrations are thus localized in the region of cytoplasm that is opposite to podocytes foot processes and filtration slit across the basement membrane (Satchell Braet.
