Heart beat
The heart controls the heart beat and the lungs control breathing
If I do not recall, Is it Hitchcock?
Yes
Your heart would not beat in a regular pattern. The pacemaker (the natural one) is there to control the beat of your heart which is why when you run your heart beat gets faster to pump more blood around the body. If you do not have one then your heart beat wont beat fast enough if your running or maybe not fast enough at all. That is even if it beats at all>
Maybe. Although the heart muscle is a class of its own, through deep breathing techniques, you can slow down your heart beat, conversely, if you are going through very strong emotions, you can speed up your heart beat.
the Sino Atrial Node (SA Node) is the pace maker of the heart that receives singles from the brain.
Nope- that is why they are involuntary. You cannot will your heart to beat- or stop beating.
While most of us are unaware of our heart beat which is under control of the "autonomic" part of our nervous system, some people can learn to control the heartbeat. For instance rifle marksmen can stop their hearts for a time while they shoot so as not to shake the gun.
