Questions & Step-by-Step Solutions

What is the primary effect of the parasympathetic nervous system?
  • Step 1: Understand that the nervous system has two main parts: the sympathetic and parasympathetic nervous systems.
  • Step 2: Know that the sympathetic nervous system is responsible for 'fight or flight' responses, which prepare the body for action.
  • Step 3: Learn that the parasympathetic nervous system is the opposite; it helps the body relax.
  • Step 4: Remember that the primary effect of the parasympathetic nervous system is to promote 'rest and digest' activities.
  • Step 5: Recognize that this means it helps increase digestive activity, allowing the body to process food and conserve energy.
