Ammonia is a breakdown product of proteins that is toxic to vertebrates. The body needs to get ammonia out of the body. By itself, ammonia is a small volatile molecule that will leak back and forth through cell and vessel membranes, making it hard for it to be gathered and excreted. Urea is made of two ammonia molecules. Because it is bigger, it is no longer volatile and cannot pass through membranes without special channels or transporters. This allows it to me concentrated in the urine for excretion from the body.
liver usually converts ammonia to urea
Our liver converts ammonia into urea. This urea is excreted out in the urine.
the liver filters the nitrogen out if your blood
Urea is produced in the liver and is a metabolite of amino acids. Excess ammonium ions are also converted to urea.
No. Ammonia and urea are distinct chemical compounds, as are their nitrates.

urea
AMMONIA and carbon-di-oxide combines in liver to make urea.
Yes.
liver
The liver produces urea when it metabolises (breaks down) proteins. This is done in hepatocytes (liver cells). Amino acids are first broken down into ammonia, which is highly soluble and toxic in the blood plasma, so ammonia is joined with carbon dioxide to make urea, this is less soluble and less toxic but a build up of urea is toxic in the blood. Urea is then transported in the blood to be filtered out by the kidneys.
Urea is made in the body by the liver, it is a by product produced in the process of removing ammonia, Ammonia is extremely toxic for the human body. Urea is then excreted from the blood filtered through the kidneys.
Ammonia is present in the human body and converted into urea by the liver. Those with liver problems can have too much ammonia in the body thus developing potentially dangerous illness.
