Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What stage of urine formation creates a plasma-like filtrate of the blood?
A
Glomerular filtration
B
Tubular reabsorption
C
Tubular secretion
D
Water conservation
Explanation: 

Detailed explanation-1: -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: -Filtrate is produced by the glomerulus when the hydrostatic pressure produced by the heart pushes water and solutes through the filtration membrane. Glomerular filtration is a passive process as cellular energy is not used at the filtration membrane to produce filtrate.

Detailed explanation-3: -Filtration. During filtration, blood enters the afferent arteriole and flows into the glomerulus where filterable blood components, such as water and nitrogenous waste, will move towards the inside of the glomerulus, and nonfilterable components, such as cells and serum albumins, will exit via the efferent arteriole.
