Which is an accurate pairing of a key excretory function with its definition?

a. Filtration happens when blood pressure forces water, nitrogenous waste, and valuable solutes from the blood into the collecting duct.
b. Reabsorption is the reclamation process that returns valuable solutes and water to the nephron from the capillaries.
c. Secretion transports certain toxins, drugs, and excessive ions from the filtrate to the capillaries.
d. Excretion moves urine, the processed filtrate, out of the kidney, through the ureter, the bladder, and finally out of the body via the urethra.
e. Reabsorption is the process in which toxins, drugs, and excessive ions that remain in the blood after filtration are transported into the nephron for disposal in the urine.


Answer: d. Excretion moves urine, the processed filtrate, out of the kidney, through the ureter, the bladder, and finally out of the body via the urethra.
