Which organ synthesise Urea?
Answers
Answer:
Urea (also known as carbamide) is a waste product of many living organisms, and is the major organic component of human urine. This is because it is at the end of chain of reactions which break down the amino acids that make up proteins. These amino acids are metabolised and converted in the liver to ammonia, CO2, water and energy. But the ammonia is toxic to cells, and so must be excreted from the body. Aquatic creatures, such as fish, can expel the ammonia directly into the water, but land-based animals need another disposal method. So the liver converts the ammonia to a non-toxic compound, urea, which can then be safely transported in the blood to the kidneys, where it is eliminated in urine.

An adult typically excretes about 25 grams of urea per day. As urea goes stale, bacteria convert it back into ammonia, which gives the familiar pungent smell of lavatories. Any condition which impairs the elimination of urea by the kidneys can lead to uremia, a buildup of urea and other nitrogen wastes in the blood that can be fatal. To reverse the condition, either the cause of the kidney failure must be removed, or the patient must undergo blood-dialysis to remove the wastes from the blood.

Answer:
liver
Explanation:
Urea is produced in the liver.
Explanation:
The body is unable to store proteins or amino acids, the products of protein metabolism.
When we ingest large amounts of protein, the excess amino acids from their digestion travel from the small intestine to the liver.
Here, the amino acids first undergo a process called transamination.
