Integration of Body Systems Practice Test

A whole-organism model shows a person lifting a heavy box. The model labels the skeletal system (bones), muscular system (arm muscles), nervous system (brain and nerves), and circulatory system (heart and blood). Arrows show nerve signals to arm muscles and blood moving to the working muscles. The model states: “Body systems form an integrated system.”

Which statement about coordination across systems is supported by the model?

A whole-organism model shows a person with a cut on the skin. The model labels the integumentary system (skin), circulatory system (blood), immune system (white blood cells), and nervous system (sensory nerves). Arrows show blood moving to the cut, white blood cells moving from blood to the cut, and nerve signals traveling to the brain. The model states: “Body systems form an integrated system.”

Which statement about integrated systems is supported by the model?
