ANATOMY

Detailed explanation-1: -Passive diffusion-the movement of molecules from the peritubular capillaries to the intersitial fluid within the nephron. Active transport-the movement of molecules via ATPase pumps that transport the substance through the renal epithelial cell into the lumen of the nephron.

Detailed explanation-2: -What are the two ways substances are removed from the blood and added to the forming urine? Substances are removed from the blood during glomerular filtration and tubular secretion.

Detailed explanation-3: -They pass on into the loop of Henle. Besides glomerular filtration, this is the second way by which substances are removed from the blood and added to the tubular fluid. It occurs along the whole length of the kidney tubule.

Detailed explanation-4: -Hydrogen, creatinine, and drugs are removed from the blood and into the collecting duct through the peritubular capillary network.

Detailed explanation-5: -The blood is thus cleared a particular solutes in the process of urine formation. These solutes may be removed from the blood by filtration through the glomerular capillaries or buy secretion by the tubular cells into the filtrate.
