What are the normal components of urine?

Urine normally contains water, inorganic salts, urea, uric acid, creatinine, creatine, etc.

1. Water

Urine contains about 95% of water, which is the main component of urine. It usually comes from blood. After filtration and concentration by the kidneys, urine is excreted.

2. Inorganic salts

Urine contains a variety of inorganic salts, such as sodium, potassium, chlorine, calcium, phosphorus, etc., which play an important role in maintaining electrolyte balance and acid-base balance in the body.

3. Urea and uric acid

When protein is decomposed in the body, amino acids are produced, which are converted into urea and uric acid. These substances are excreted with urine to help maintain nitrogen balance in the body.

4. Creatine and creatine are

produced when muscle activity occurs. These substances are also excreted with urine, reflecting muscle activity and metabolism.
