In reabsorption, the solutes are reabsorbed across the filtration membrane into the interstitial fluid by transport processes, such as active transport and cotransport.
|
|
|
In secretion, solutes are secreted across the wall of the nephron into the filtrate.
|
|
|
Filtration is the movement of materials across the wall of the nephron into Bowman’s capsule to form a filtrate.

Detailed explanation-1: -Answer: C. In secretion, solutes are secreted across the wall of the nephron into the filtrate. C: In secretion, solutes are secreted across the wall of the nephron into the filtrate. A: Filtration is the movement of materials across the filtration membrane into Bowman’s capsule to form a filtrate.
Detailed explanation-2: -Tubular secretion occurs throughout the different parts of the nephron, from the proximal convoluted tubule to the collecting duct at the end of the nephron.
Detailed explanation-3: -The majority of drugs do not enter the kidney tubule by glomerular filtration but do so by tubule secretion. This is an active process since drugs are carried against a favourable chemical gradient from the capillary network into the tubule.
