Final answer:
The urinary tract consists of the kidneys, ureters, urinary bladder, and urethra, which work together to filter blood, store, and eliminate urine.
Step-by-step explanation:
The four main components of the urinary tract are the kidneys, the ureters, the urinary bladder, and the urethra. The urinary system is essential for filtering blood, removing waste products, and managing water and electrolyte balance.
The kidneys initially filter the blood to form urine, which then travels through the ureters to the urinary bladder, where it is stored. When urination occurs, urine is discharged from the body through the urethra.
