What is the function of four organs in urinary system?

The urinary system is responsible for filtering waste products and excess water from the body. The four main organs of the urinary system are:

- 1. Kidneys: The kidneys are bean-shaped organs located near the middle of the back. They filter waste products from the blood, such as urea, creatinine, and uric acid. They also regulate the body's water and electrolyte balance.

- 2. Ureters: The ureters are two tubes that carry urine from the kidneys to the bladder.

- 3. Bladder: The bladder is a muscular organ that stores urine until it is passed out of the body through urination.

- 4. Urethra: The urethra is a tube that carries urine from the bladder out of the body. In males, the urethra is also part of the reproductive system and carries sperm during ejaculation.

These four organs work together to maintain the body's fluid and electrolyte balance, remove waste products from the blood, and produce urine.
