Life Science: It Takes Guts

by Texas Instruments - Simulation Lesson


  • Students will investigate the interactions that occur in specific organs of the human body during a “fight or flight” nervous reaction to fear or stress.
  • Students will relate each organ to its specific organ system.
  • Students will justify the response for each organ.
  • Students will relate the “fight or flight” response to a real-life situation.
  • Students will compare/contrast the “rest and digest” nervous response.


  • organs:  stomach, muscles, heart, eyes, sweat glands, liver, lungs, kidneys, arteries
  • organ systems: nervous, circulatory, digestive, muscular, urinary respiratory
  • “fight or flight” nervous system response
  • “rest and digest” nervous system response

About the Lesson

In this lesson, students will explore organ responses that occur during a “fight or flight” nervous reaction.

 As a result, students will:

  • Explore body specific reactions to the nervous system’s “fight or flight” response system.
  • Run a simulation involving a baseball player. With each advance of the simulation, they will use a magnifying glass to locate specific organs and their responses to the situation.
  • Students will record their data and apply these data to answer questions.
