Scenario: Body Systems
13. Ouch! You step on a tack and jerk away without even thinking. Then you decide to pick up the tack and place it back in a desk drawer.
Directly Involved Body Systems:
- Nervous System: The nervous system is responsible for processing the stimulus (the pain from stepping on the tack) and initiating a reflex action to jerk away. The sensory neurons carry the pain signal to the spinal cord, which then sends an immediate response through motor neurons to the muscles in the leg.
- Muscular System: The muscular system is directly involved in the action of jerking away from the tack. The contraction of muscles in the leg occurs rapidly as a reflex action.
14. You drink two cans of your favorite sugary soda, even though you know this is not healthy for you. You have to run to the bathroom before the next class period starts.
Directly Involved Body Systems:
- Digestive System: The digestive system is involved as it processes the sugary soda you consumed. The sugar from the soda is broken down and absorbed into the bloodstream.
- Urinary System: The urinary system is involved when you feel the need to run to the bathroom. The kidneys filter the excess sugars and fluids from your blood, leading to the production of urine, which is then expelled from the body.
