Final answer:
The urinary system's pathway begins at the kidneys, moves through the ureters to the urinary bladder, and ends at the urethra, which excretes urine from the body.
Step-by-step explanation:
The urinary system is responsible for removing waste products from the blood and regulating various bodily functions. The pathway of the urinary system starts with the kidneys, where the blood is filtered. Waste and excess water are turned into urine here. From the kidneys, the urine travels down two tubular structures called ureters, one connected to each kidney, and enters the urinary bladder. The bladder serves as a storage area for urine until the body is ready to excrete it.
During urination, urine leaves the bladder and is carried to the outside of the body by a tube called the urethra. Along with waste removal, the kidneys also perform other vital functions, such as regulating blood pressure and maintaining electrolyte balance.
