PiSS

Urine, also known as piss, is a liquid byproduct of the body secreted by the kidneys through a process called urination and expelled from the body. Urine is composed of water, salts, urea, and other waste products filtered from the blood. The color of urine can vary from pale yellow to dark amber, depending on hydration levels and diet.

Historically, urine has had various uses. It was a source of nitrogen for fertilizers and was used in tanning leather and as a cleaning agent due to the presence of ammonia. In some ancient cultures, urine was even used for medicinal purposes, though these practices are not supported by modern science.

Today, urine analysis is a common diagnostic tool in medicine. It can provide information about kidney function, hydration status, and the presence of various diseases such as diabetes or urinary tract infections. The chemical composition of urine can reveal a great deal about an individual's health.
