1 of 15
What is the pulmonary circuit?
Carries deoxygenated blood to lungs and oxygenated blood back to heart
2 of 15
What is the systemic circuit?
Carries oxygenated blood to body and deoxygenated back to heart
3 of 15
Explain the conduction system
SA node creates impulse, AV node receives and delays impulse, Bundle of His carries impulse down septum + splits it in two, bundle branches carry impulse to bottom of ventricles, purkinjie fibres make ventricles contract
