The passive process performed by the glomerulus that removes molecules based on size is ____
A
glomerular filtration
B
tubular reabsorption
C
glomerular reabsorption
D
tubular secretion
Explanation: 

Detailed explanation-1: -What is glomerular filtration? Glomerular filtration is the first step in making urine. It is the process that your kidneys use to filter excess fluid and waste products out of the blood into the urine collecting tubules of the kidney, so they may be eliminated from your body.

Detailed explanation-2: -Example-small ions like sodium and potassium pass freely but, haemoglobin and albumin have practically no permeability. Thus glomerular filtration is non selective as, though all substances must move through the glomerular membrane i.e. plasma and dissolved substances but no blood cells and large blood proteins.

Detailed explanation-3: -This process is referred to as ultrafiltration. Glomerular Filtration Rate or GFR is the rate at which the kidneys form the filtrate in a minute.

Detailed explanation-4: -The glomerular filtration barrier selectively filters molecules based on size (70 kDa), electrical charge (the more cationic, the more permeable), and capillary pressure.
