In healthy individuals, the lower urinary tract has two discrete phases of activity: the storage (or guarding) phase, when urine is stored in the bladder, and the voiding phase, when urine is released through the urethra. Describes how the urinary tract works, why it’s important, what affects the amount of urine produced, and how to keep the urinary tract healthy. Urine is liquid waste that your kidneys make to remove excess fluids and waste products from your body. It mostly consists of water, but it also contains waste products, salt and electrolytes. Foods and medicines can change the color of urine. But a color change also could be a sign of disease. Urine is the fluid excreted by the kidneys of vertebrates to clear the bloodstream of excess water and metabolic by-products including urea, uric acid, and creatinine. In mammals, urine travels from the kidneys via the ureters to the bladder for storage until urination. Urine color is a simple yet informative indicator of your health, reflecting hydration and possible medical issues. This chart helps you identify what your pee color means and when it’s time to consult a healthcare provider. Clear urine often indicates that you’re drinking more water than necessary. Urine contains various chemicals, minerals, toxins, bacteria, and red and white blood cells. A urine test, also known as a urinalysis, can reveal the presence and amounts of these substances, which can provide clues to specific conditions. But the basic details of your urine — color, smell, and how often you go — can give you a hint about what’s going on inside your body. Pee is your body’s liquid waste, mainly made of water. When your urinary system removes toxins and wastes from your body, it comes out as pee (urine). To be able to pee, your body must pass this waste through a series of organs, ducts and tubes. Your kidneys make urine by filtering wastes and extra water from your blood. The waste is called urea. Your blood carries it to the kidneys. From the kidneys, urine travels down two thin tubes called ureters to the bladder. The bladder stores urine until you are ready to urinate.
