What is the Difference Between Urea and Urine?
🆚 Go to Comparative Table 🆚Urea and urine are different substances with distinct characteristics and functions. Here are the main differences between them:
- Origin: Urea is a nitrogen-containing waste substance produced in the liver from ammonia, which is a byproduct of protein breakdown. Urine, on the other hand, is a liquid generated in the kidneys as a result of blood filtration.
- Composition: Urea is a colorless crystalline substance. Urine is a watery, yellowish fluid held in the bladder and expelled through the urethra, consisting of water, urea, inorganic salts, creatinine, ammonia, and pigmented products.
- Function: Urea is the major nitrogenous waste removed by urine. Urine is a liquid that humans and other animals excrete, serving as a means of eliminating waste products from the body.
- Form: Urea exists in a solid form. Urine is a liquid.
- Odor: Urea is odorless. Urine has an unpleasant smell due to the presence of various waste products and chemicals.
In summary, urea is a waste product formed in the liver as a result of protein breakdown, while urine is a liquid generated in the kidneys that serves as a means of excreting waste products, including urea, from the body.
Comparative Table: Urea vs Urine
Here is a table highlighting the differences between urea and urine:
Feature | Urine | Urea |
---|---|---|
Definition | Urine is a watery, yellowish fluid generated in the kidneys as a result of blood filtration, containing nitrogen molecules like urea and other waste products. | Urea is a colorless crystalline substance that is the most common nitrogenous waste removed by urine, formed in the liver from ammonia as a byproduct of nucleic acid and amino acid breakdown. |
Form | Urine is a liquid. | Urea exists in a solid form. |
Composition | Urine consists of water, urea, inorganic salts, creatinine, ammonia, and pigmented products. | Urea is a component of urine, making up about 2% of its composition. |
Production | Urine is produced in the kidneys through a process called urination. | Urea is first formed in the liver from ammonia and then filtered by the kidney into urine. |
Odor | Urine has an odor. | Urea is odorless. |
Urine is a liquid by-product of the body secreted by the kidneys, while urea is a solid waste product found in urine. Urea is a processed form of ammonia that is non-toxic to mammals, unlike ammonia, which can be highly toxic.
