The correct answer is that ammonia is removed from the blood by the liver, which processes it into urea, and discharging it into the circulation.
The liver plays an essential function in the metabolism of proteins. The cells in the liver modify amino acids in foods so that they can be utilized to generate energy, or make fats or carbohydrates.
A toxic component known as ammonia is a waste-product of this procedure. The liver cell transform ammonia to a much less toxic component known a urea, which is discharged into the blood. Urea is then translocated to the kidneys and is removed out of the body in the form of urine.
