Why can the heart continue to pump blood even if the nervous system is damaged?
It receives signals from the brain stem.
It has its own chemical/electrical system.
It relies on skeletal muscle contractions.
It can store enough energy to function independently for a long time.
What factors can cause the heart's pumping mechanism to stop?
High blood pressure and stress.
Lack of oxygen, a blockage, or direct injury.
Excessive exercise and dehydration.
Emotional shock and sudden fright.
What is the primary role of the SA Node in the heart's electrical conduction system?
To filter waste products from the blood.
To act as the heart's natural pacemaker, initiating the electrical impulse.
To regulate blood pressure throughout the body.
To connect the atria and ventricles for blood flow.
What is the main function of the Purkinje Fibres in the heart?
To carry oxygenated blood to the heart muscle.
To spread electrical charge throughout the myocardium, causing contraction.
To prevent backflow of blood between heart chambers.
To produce hormones that regulate heart rate.
