pathways of the circulation of blood
1) systemic - the rest of the body
2) pulmonary - includes whatever is going/coming to and from the lungs
both include arteries, arterioles, capillaries, venules, and veins!
heart’s electrical conduction system
sinoatrial/SA node
atrioventricular/AV node (aka gatekeeper)
bundle of His
Purkinje fibers
Purkinje fibers cause the ventricles to contract and pump blood into the pulmonary artery and the aorta
*** this is the cardiac cycle
heart’s electricity is mapped out by a ___
an electrocardiogram (EKG)
main body systems that contribute to homeostasis
endocrine and nervous systems
