Function of SA node - correct answer - Cells depolarize and cause AV node and Bachman's bundle to depolarize
- Atria then contract and the signal is sent down the left and right branches to the AV node
- Pacemaker of the heart
Function of AV node - correct answer Signal goes to bundle of His, splits into Purkinje fibres, and causes the ventricles to contract
