Question

The waste matters (urea) are transported by

• A. Blood
• B. Lymph
• C. RBCs
• D. None of the above

Answer 1

The correct option is A Blood

Urea is synthesized in the liver from ammonia and carbon dioxide. The urea synthesis is a five-step cyclic process, with five distinctive enzymes. This urea is released into the bloodstream from the liver cells. Through blood, urea is transported to kidneys where the blood is filtered and urea is passed out of the body in the urine. Hence the waste matters (urea) are transported by the blood.

So, the correct answer is 'Blood'.
