The amount of T3 and T4 produced by the thyroid gland is controlled by the pituitary gland at the base of the brain. It does this by secreting thyroid stimulating hormone (TSH). When the levels of T4 and T3 fall, the pituitary secretes more TSH. When T4 and T3 levels rise, the pituitary secretes less TSH.
Ammonia is a chemical made by bacteria in your intestines while you process protein. Your body treats ammonia as a waste product. It turns it into glutamine and urea. Then the urea travels to the kidneys and is eliminated in your urine.Ammonia will build up if the liver is too damaged to get rid of urea.our body treats ammonia as a waste product.

Since ammonia is not a healthy thing to have in high amounts in your body, it is processed by the body into urea. Urea is then carried in the blood to the kidneys where it is removed and filtered out in the urine. Blood Urea Nitrogen is an indicator of how much ammonia is being transferred into urea.
