Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which stage of urine production involves the removal of substances from the bloodstream?
A
reabsorption
B
excretion
C
filtration
D
secretion
Explanation: 

Detailed explanation-1: -As blood flows through the glomerulus, blood pressure pushes water and solutes from the capillaries into the capsule through a filtration membrane. This glomerular filtration begins the urine formation process.

Detailed explanation-2: -Urine is formed in three main steps-glomerular filtration, reabsorption and secretion.

Detailed explanation-3: -The kidney glomerulus filters blood mainly based on particle size to produce a filtrate lacking cells or large proteins. Most of the ions and molecules in the filtrate are needed by the body and must be reabsorbed farther down the nephron tubules, resulting in the formation of urine.

Detailed explanation-4: -The glomerulus is nestled within a region of the kidney called the Bowman’s Capsule. This is where filtration occurs.
