Where are the electrical signals for the conduction process created?
SA Node
AV Node
Purkinje Fibres
Bundles of His
1.atria contract
2. AV node
3. Bundle of His
4.Purkinje fibers
5. SA node
6. ventricles contract
The SA node fires at a rate of
40-60 bpm
80-90 bpm
60-80 bpm
60-100 bpm
Why is there a delay in the signal between the atria and ventricles,
to allow extra time for diastole to occur
to ensure the heart is fully repolarized
to ensure the left and right atrias beat as one.
allowing ventricles to fill with blood before contracting as one.

Why is it wrong to say that arteries contain “oxygenated blood” and veins contain “deoxygenated blood?” Explain and give at least 1 example (Make sure to write the answer in your own words)
Does the heart depolarize before it begins to contract or do the two events occur at the same time? Explain why this "timing" between depolarization and contraction is necessary for normal heart functions. (Make sure to write your answer in your own words).
