What are the two ways substances are removed from the blood and added to the forming urine?
A
glomerular filtration and tubular secretion
B
glomerular filtration and tubular reabsorption
C
tubular secretion and tubular reabsorption
D
tubular reabsorption and micturition
Explanation: 

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: -This process is called secretion. The secreted ions combine with the remaining filtrate and become urine. The urine flows out of the nephron tubule into a collecting duct.

Detailed explanation-3: -Hydrogen, creatinine, and drugs are removed from the blood and into the collecting duct through the peritubular capillary network.
