FOCUS QUESTION

How does the urinary system filter blood and remove waste?

The map breaks this topic into its core concepts, connected by labeled relationships. Each link is written so it can be read as a complete statement — not just an unlabeled line between boxes.

Concepts and relationships

  • Urinary System is centered on the Kidneys.
  • Kidneys filter blood in Nephrons.
  • Nephrons perform Filtration.
  • Kidneys drain into Ureters.
  • Ureters carry urine to the Bladder.
  • Bladder empties through the Urethra.
  • Nephrons produce Urine.

How to read this map

Follow blood into the kidneys, where nephrons filter it into urine, then trace urine down the ureters to the bladder and out the urethra.

Learning objectives

  • Order the organs of the urinary tract.
  • Explain the filtering role of nephrons.
  • Describe how urine is stored and released.
  • Relate structure to waste removal.
