Explanation:
Detailed explanation-1: -The urea cycle or ornithine cycle converts excess ammonia into urea in the mitochondria of liver cells. The urea forms, then enters the blood stream, is filtered by the kidneys and is ultimately excreted in the urine.
Detailed explanation-2: -The liver is the only site where urea is synthesized and ultimately excreted by the kidneys.
Detailed explanation-3: -Urea production occurs in the liver and is regulated by N-acetylglutamate. Urea is then dissolved into the blood (in the reference range of 2.5 to 6.7 mmol/L) and further transported and excreted by the kidney as a component of urine.
