Expert Answer:

  • Reflex action is an automatic, quick and involuntary action in the body brought about by a stimulus.
  • All reflex actions are involuntary in nature but all involutary actions are not reflexes. For example - The beating of heart and peristalsis are involuntary actions, but not reflex action.
  • Reflex actions are done to meet emergencies where as an involuntary action is not done for emergencies, but to fulfill a critical life process as circulation of blood, movement of food in food pipe through peristalsis.
