How are involuntary actions and reflex actions different from each other?

(N/A) Involuntary actions are those that cannot be consciously controlled,such as the movement of food in the alimentary canal or the beating of the heart. These actions are directly regulated by the brain.
Reflex actions are sudden,automatic,and involuntary responses to a stimulus that do not involve conscious thought or processing by the brain. For example,closing eyes immediately when exposed to bright light. Unlike involuntary actions,reflex actions are primarily controlled by the spinal cord,allowing for a faster response.
