Answer:

These muscles push materials like food or blood through organs. Unlike skeletal muscle, smooth muscle can never be under your control.

Explanation:

Cardiac muscle is also an involuntary muscle, found only in the heart. Cardiac muscle differs from skeletal muscle in that it exhibits rhythmic contractions and is not under voluntary control. The rhythmic contraction of cardiac muscle is regulated by the sinoatrial node of the heart, which serves as the heart's pacemaker.

Answer:

It would be REALLY hard to live

Explanation: If cardiac muscles turned from involuntary to voluntary, you would have to constantly think and control your heart's beating and other veins/arteries' functions. Sure, you could grow to instinctively beat your heart like breathing, but overall it wouldn't be the best since the brain is more occupied. On the plus side, you could rid yourself of heart problems (Not including infections or defects) with the right skill if you are considering that the cardiac muscles contract or relax. Soft muscles, like the ones making up most of our organs, are mostly are involuntary, so that would mean that almost everything would be voluntary. From stomach contractions to urination, soft muscles control all. If soft muscles were voluntary, in short, the brain would be overloaded with tasks and would probably be exposed to an unhealthy amount of 'stress' which could make the brain fail, just like dying from overwork.

Answer:

I say it's true because it receives the food and air from mouth and nasal cavities.
