Ions and breakdown products of organic molecules are actively transported from the peritubular capillaries to the filtrate within the nephron by ____.
A)tubular secretion
B)tubular reabsorption
C)glomerular filtration
D)tubular osmosis
E)glomerular excretion

Question

Quizplus · Accepted Answer

Tubular secretion is the process by which ions and breakdown products of organic molecules are actively transported from the peritubular capillaries to the filtrate within the nephron. Tubular reabsorption is the process by which substances are transported from the filtrate back into the peritubular capillaries, glomerular filtration is the process by which substances are filtered from the blood into the nephron, tubular osmosis is the movement of water from an area of low solute concentration to high solute concentration, and glomerular excretion is not a recognized physiological process.
