West Coast EMT BLOCK
EXAM #2 100% VERIFIED
ANSWERS 2024/2025
What is the electrical conduction system of the heart?
- A network of specialized tissue that is capable of conducting electrical current runs
throughout the heart.
- The flow of electrical current causes smooth, coordinated heart contractions.
- The contractions produce the pumping action of the heart.
- Each mechanical contraction is associated with two electrical processes: 1.
Depolarization: electrical charges on the surface of the muscle cell change from positive
to negative 2. Repolarization: the heart returns to its resting state, and the positive
charge is restored to the surface
- Electrical impulses begin high in the atria at the sinoatrial node, travel to the
atrioventricular node and bundle of His, and then move through the Purkinje fibers to
the ventricles.
What are the layers of the blood vessels?
Adventitia (outer layer), tunica media (middle layer), tunica (intima) inner layer
What is the function of the adventitia (outlet layer)?
- provides structural support and shape to the vessel
