What is the difference between a voluntary and an involuntary action? Which kind of action is digestion? Explain your choice.

A voluntary action is under the control of one's will, means under the control of the brain.

Example- Dancing, Eating, Writing, etc.

An involuntary action is not under the control of one's will, it is controlled by the spinal cord.

Example- Breathing, Respiration, Blinking eyelids etc.

Digestion is a kind of involuntary action because it occurs inside our body unknowingly by the digestive system.
