The excretory system constantly cleans your body by removing waste. It eliminates extra water, salts, and harmful substances by urinating, sweating, and breathing.
A key part of this system is the urinary system, which filters blood and removes liquid waste as urine.
It includes four main organs: the kidneys, ureters, urinary bladder, and urethra. Together, they clean the blood and remove waste.
It all begins in the kidneys, the two bean-shaped organs located near the middle of the back, on either side of the backbone.
They filter blood and remove wastes, including urea, a substance formed when the body breaks down proteins. This waste combines with extra water to form urine.
Urine then travels through the tube-shaped ureters to the urinary bladder, a hollow, muscular organ, where it’s stored.
Finally, it's released from the body through an opening called the urethra.
This released urine ranges from colorless to dark yellow. Pale yellow indicates good hydration, while dark urine may mean your body needs more water.
