The urinary system consists of the kidneys, ureters, bladder, and urethra. This system is responsible for removing wastes and extra fluid from the body in the form of urine. It also keeps the levels of electrolytes in the body stable.
The kidneys filter the blood through specialized capillaries in order to remove waste materials and produce urine.
The ureters drain urine from the kidneys and transport it to the bladder, where it is stored until it is released outside the body through the urethra during urination.
