What is pee?

Here's some information about pee (also known as urine):

Urine is a liquid byproduct of metabolism in humans and many other animals. It's expelled from the body via the urethra during urination.

• Composition: Urine is primarily water, but it also contains various dissolved waste products such as urea, creatinine, salts, and other organic compounds. The exact composition varies depending on factors like hydration levels, diet, and overall health.

• Function: The main function of urine is to remove waste products from the bloodstream and maintain fluid and electrolyte balance in the body. The kidneys filter the blood and produce urine, which is then transported to the bladder for storage until it's eliminated.

• Color: Normal urine color typically ranges from pale yellow to amber. The color is primarily due to the presence of urobilin, a byproduct of bilirubin breakdown. Changes in urine color can indicate various health conditions or be influenced by certain foods or medications. For example, dehydration can lead to darker urine, while certain medications can turn urine bright orange or blue-green.

• Odor: Normal urine has a mild odor. A strong or unusual odor can sometimes indicate a medical condition, such as a urinary tract infection (UTI) or diabetes. Certain foods, like asparagus, can also affect urine odor.

• Medical Significance: Urine analysis, or urinalysis, is a common diagnostic test used to detect various medical conditions, including kidney disease, diabetes, infections, and liver problems. Testing urine can reveal abnormalities in its composition, such as the presence of protein, glucose, blood cells, or bacteria.
