coronary loop
systemic loop
systolic loop

arteries
capillaries
shunts

False
Which of the following is the correct sequence for the intrinsic conduction system?
SA node -> AV node -> AV bundles -> Purkinje fibers -> bundle branches
AV node -> AV bundles -> SA node -> bundle branches -> Purkinje fibers
