FranNo, hemoglobin does not break down into urea in the intestines. Hemoglobin is broken down by macrophages in the liver and spleen into heme and globin, which are further processed into bilirubin and amino acids, respectively. Urea is formed in the liver as a byproduct of protein metabolism and is excreted in the urine by the kidneys.

Urease hydrolyzes urea to form what?
Urease hydrolyzes urea to form ammonia and carbon dioxide.
Why is the concentration of urea strong in urine?
The concentration of urea is high in urine because urea is a waste product produced by the liver when it breaks down proteins. The kidneys then filter urea from the blood and excrete it in urine to maintain the body's nitrogen balance.
What toxic byproduct is naturally produced when your body breaks down proteins and lipids?
Ammonia is a toxic byproduct produced when the body breaks down proteins and lipids. It is converted to urea in the liver and excreted in urine.
What is the organ that produces urea in our body?
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.
What poisonour chemical does the kidneys filter from your blood?
The kidneys filter urea, a waste product produced when the body breaks down proteins. If urea builds up in the blood, it can become toxic and harmful to the body's organs and tissues.
