Expert Answer:

All reflex actions are involuntary in nature but all involutary actions are not reflexes as the beating of heart is an involuntary action but is not reflex action.

 A reflex action may involve any muscle or a gland as we withdraw our hand on touching a hot object butall involuntary actions involve only smooth i.e., involuntary or cardiac muscles. Reflex actions are at the level of spinal cord whereas the involuntary actions generallly involve brain too. Reflex actions are done to meet emergencies where as an involuntary action may or may not be for just meeting an emergency but may be a critical process as circulation of blood, swallowing of food, movement of food in food pipe, etc.
