Key Differences
Urea is used in various industrial applications, including fertilizers, and can also be synthesized. Urine is a biological waste product expelled by animals, including humans, and is not generally synthesized, although it has some historical and modern applications, like in agriculture as a fertilizer.

Urea is a specific organic compound with the formula (NH2)2CO, and it is produced in the liver as a result of protein metabolism. Urine, on the other hand, is a complex fluid produced by the kidneys that contains urea among many other dissolved substances, such as salts and creatinine.

Urea can be isolated as a solid or concentrated substance, allowing for easy storage and transport. Urine is a liquid and is usually not stored for long periods, except for medical testing, due to its organic nature and potential for bacterial growth.

Both urea and urine are central to the study of human physiology and medicine. Urea levels can be indicative of liver and kidney function, while urine tests are often broader indicators of health, capturing data on hydration, drug use, and other metabolic processes.
