In Contrast to Glomerular Filtration, Tubular Reabsorption _______

Question

In contrast to glomerular filtration, tubular reabsorption _______.
A) works against homeostasis
B) takes place mainly in the collecting ducts
C) is highly selective
D) returns metabolic wastes to the blood

Accepted Answer

Tubular reabsorption is highly selective, meaning that substances that are needed by the body, such as glucose and amino acids, are reabsorbed into the bloodstream, while waste products, such as urea and creatinine, are left in the tubules to be excreted as urine.
