What is the only muscle that can contract itself?
The heart is self-contracting or rather it has a high susceptibility to depolarization.
What is the time when the heart chambers are contracting at their maximum force to push blood out of the heart and into the arteries?
When the heart chambers are contracting at their maximum force to push blood out of the heart it's called systole.
The vessels that carry oxygen to mycardial cells are called what?
Coronary arteries carry oxygen-rich blood to the tissues of the heart muscle. The oxygen diffuses within myocardial capillaries.
What does the heart muscle do in between beats?
Your heart is still a muscle, and thus forth needs to rest in between beats. Rest.
What does muscles mean?
