urine

Urine is a liquid waste product produced by your kidneys, which filter excess water, salts, and metabolic byproducts like urea from your bloodstream. It flows from the kidneys into the bladder via the ureters, where it is stored until you urinate. Urine's composition can vary based on hydration, diet, and health, but it typically contains water, salts, and waste substances. Its primary role is to help the body eliminate unwanted or excess substances, maintaining fluid and electrolyte balance, and removing toxins to keep you healthy.
