1. Kidneys:
- Two bean-shaped organs located on either side of the spine, just below the ribs.
- Function: Filter waste products from the blood, produce urine, regulate blood pressure, and balance electrolytes.
2. Ureters:
- Two narrow tubes that connect each kidney to the bladder.
- Function: Carry urine from the kidneys to the bladder.
3. Bladder:
- A hollow, muscular organ located in the pelvic area.
- Function: Stores urine until it is ready to be eliminated.
4. Urethra:
- A single tube that carries urine from the bladder out of the body.
- Function: Transports urine from the bladder to the outside of the body.
5. Nephrons:
- Tiny filtering units located within the kidneys.
- Function: Each kidney contains millions of nephrons, which are responsible for filtering waste from the blood and forming urine.
6. Renal Pelvis:
- A funnel-shaped structure inside each kidney that collects urine from the nephrons and directs it into the ureter.
7. Sphincters:
- Muscles that control the flow of urine.
- Function: The bladder has two sphincters: an internal sphincter (involuntary muscle) and an external sphincter (voluntary muscle) that help regulate the release of urine.
These components work in a coordinated way to maintain the body's internal balance and remove waste products.
