This is a nephron process that results in a substance in blood entering the already formed filtrate.
This layer of filtration membrane is composed of collagen fibers and proteoglycans in a glycoprotein matrix. This occurs when stretching triggers contraction of smooth muscle walls in afferent arterioles.
Collecting duct.
Renal corpuscle (or glomerulus).
Active transport—the movement of molecules via ATPase pumps that transport the substance through the renal epithelial cell into the lumen of the nephron.
