No one knows why we yawn. It isn't just boredom or sleepiness. It can be associated with some diseases such as MS. Even unborn infants yawn.
involuntary muscle
it is important because we cant tell our selves breathe,breathe,breathe. Our brain knows so we don't control it.
Examples of this are your heart and lungs. You cant control your heartbeat and your lungs are considered involuntary because it does not require additional energy to breath, its your body's NATURAL instinct. Any movement or process your body does naturally is considered involuntary by the way :) Hope this helped!
The vast majority is involuntary. The lower bowels can be controlled, but very limited in nature.
They are involuntary. You don't have to remind yourself to make your heart beat, so it is involuntary.These are involuntary in nature.

A voluntary response is under conscious control, meaning you can choose whether or not to perform the action. An involuntary response is not under conscious control and occurs automatically, such as a reflex or a reaction controlled by the autonomic nervous system.
Voluntary muscles chose to be moved and your will. For example your pectoral muscles and or your biceps. You can flex them and move them to your control by giving in nerve signals from your brain to that muscle. Involuntary muscles have automatic neurological control. Example would be the heart, you don't think about it but it still beats, and if you do exercise your brain automatically tells your heart to beat faster to pump more blood into your body.
Yes you cant stop it even if you wanted to. Therefore it is involuntary.
Breathing is completely involuntary. You have to breath . Even with out thinking you will breath.
