✓

Answer

Difference between involuntary and reflex actions is as follows:
Involuntary actions
Reflex actions
It is a set of muscles movement over which we do not have control. Such actions are controlled by brain. For example-contraction of muscle of our digestive tract, beating of heart etc.
It is rapid, spontaneous and involuntary activity that is produced in response to a stimulus. It is controlled by spinal cord. Example-removal of hand with jerk when someone touches a hot object.
