When is the last time that you consciously and deliberately moved a meal through your digestive system? Does it ever happen without your constant, deliberate control?
Involuntary.
Digestion is an involuntary process. You do not control digestion, it just happens.
You have no control over it, and do not tell your body to do it, therefore it is involuntary, just like you don't tell your heart to beat, it just does it.
The diaphragm because breathing is an involuntary movement.

involuntary movements are move that we can't controlled except for the movement of the heart lungs etc. examples are like blinking we can't control blinking so that is considered an involuntary movement.
voluntary, you cause your lips to form the shape to whistle, and cause the air to be pushed out. if whistling were involuntary, you would do it without making an effort (like your heart pumping, digesting things, etc)
