What is the major process by which the kidney removes waste products from the blood called?
A. Tubular secretion.
B. Tubular sublimation.
C. Tubular reabsorption.
D. Glomerular filtration.
The process by which the kidney removes most of the waste products from the blood by pure filtration through the glomerular membrane is known as glomerular filtration. Hydrogen ions undergo tubular secretion into the glomerular filtrate, whereas substances such as glucose, amino acids, and potassium ions are actively reabsorbed by the tubular membrane. Sublimation is a physical change from the solid directly to the gaseous state, and does not apply to the kidney or any other organ.
