Correct Answer:
Liver but eliminated mostly through kidneys
- Principal Waste: In humans, the primary nitrogenous waste is urea (ureotelic excretion).
- Synthesis: Urea is produced in the liver via the Ornithine cycle (Urea cycle) from ammonia.
- Transport and Elimination: The liver releases urea into the blood, which is then filtered and eliminated by the kidneys.
- Conclusion: Synthesized in liver, eliminated through kidneys.
