Question

The amber colour of the urine is due to
A. Urochrome
B. Bilirubine
C. Bileverdine
D. Chlorides

Answer 1

Hint: The urinary tract comprises two kidneys, two ureters, one urinary bladder and a urethra. All these components work together efficiently to carry out the process of urination. It is stored in a distensible urinary bladder before being expelled out.

Complete answer:
The liquid waste excreted out of the body with the help of the excretory system is called urine. It is mainly composed of water, salt, electrolytes like potassium and phosphorus, and urea. The kidneys filter toxins and metabolic waste products out from the blood to produce urine. The urine is carried by the ureters to the urinary bladder and then with the help of urethra it is excreted out of the body.
The colour of normal urine is amber i.e. light yellow. This is due to the presence of a pigment called urochrome. Urochrome is an end product of protein metabolism. The colour may often change from light to dark depending on how much concentrated or diluted the urine is.
So, the correct answer is “Option A”.

Additional Information:
A healthy bladder has the capacity to hold 2 cups of urine easily for 2 to 5 hours.

Note:
Accumulation of waste and toxins in the blood is harmful. Thus, it is important to have a normal intake of water to flush out the toxins at regular intervals in the form of urine. The colour of urine is also affected by the intake of medicines and certain food types. A red or pink coloured urine is due to the intake of beets, or berries. A deep amber or honey coloured urine is indicative of liver disease. Whereas, foamy urine suggests the presence of protein in the urine.
