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: -Excretion : Removal of metabolic waste products from the body (mainly urea and uric acid). Metabolic wastes and excess ions are filtered out of the blood, along with water, and leave the body in the form of urine.

Detailed explanation-3: -Urine is formed in three main steps-glomerular filtration, reabsorption and secretion.

Detailed explanation-4: -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-5: -Between these arterioles forms, a network of capillaries called the glomerular capillaries of the glomerulus. The Bowman’s capsule is a cup-shaped structure in which this glomerulus is located. The glomerulus along with the Bowman’s capsule achieve the filtration of blood to form urine.
