Key Learning Points
Conduction Tissue
Atrial Internodal Pathways Page 8
- Atrial Internodal Pathways(a) rapidly conduct impulses from the SA Node to the AV Node(b) and atrial muscle(c)
- Rapid conduction allows for efficient coordinated depolarization and contraction of the atria.
AV Node Functions Page 9
- Delay impulses traveling from the atrium to the ventricles allowing time for atrial contraction to push blood into the ventricles before they contract.
- Prevents conduction of too many impulses from the atria to the ventricles in cases of fast atrial rhythms.
