    Study Notes

    ### Organ Systems

    • The human body is organized into systems
    • Organ systems consist of multiple organs working together for a common goal
    • There are 11 organ systems:
      • Circulatory: Responsible for blood supply
      • Respiratory: Responsible for breathing
      • Digestive: Responsible for digestion and absorption
      • Nervous: Responsible for sensation and movement
      • Excretory: Responsible for waste elimination
      • Endocrine: Responsible for hormonal control
      • Reproductive: Responsible for reproduction
      • Lymphatic: Responsible for defense
      • Skeletal: Responsible for support
      • Muscular: Responsible for movement

    Human Organs

    • There are approximately 79 human organs
    • This number is not standardized
    • If organs worked independently, the result would be chaos
