Question

a. Bile
b. Lymph
c. Cholesterol
d. Urochrome

Answer 1

Hint: Urine is a by-product of metabolism in the body. It’s mainly made of water, salt, electrolytes (ex-potassium, phosphorus), urea and uric acid. Before passing from the body urine flows from kidney to the ureter, bladder and finally to the urethra. Urine carries a yellow pigment due to it the natural color of urine will be light yellow if anyone is staying hydrated.

Complete answer:
- The change in urine indicates some specific changes in the body. The color of urine is referred to by doctors as urochrome.
- This pigment found in urine is known as urochrome or urobilin. The appearance of pigment is decided by the amount of water a person drinks. Higher water levels in the body makes the urine diluted and the color of urine becomes lighter.
- The presence of bile in urine makes the color of the urine brown. The condition is defined as choluria. Choluria is a common symptom seen in patients suffering from liver diseases(Eg. cirrhosis, hepatitis)
- Small amount of cholesterol is always present in urine. It does not change the color of urine but the presence of lymph changes the urine color into milky white. It’s a rare condition known as chyluria.

Hence, the correct answer is option (D).

Note: Pale yellow color urine is a good indicator of good hydration. Any type of change in urine colors will happen due to different molecules. Examination of urine can help to find certain diseases like diabetes mellitus. Staying hydrated will always help in living a healthy life.
