Q

Structures

A

Heart: 4 chamber muscular pump
Blood: circulates nutrients and oxygen to all parts of body and transports waste
Blood vessels:
Arteries: carry blood away from heart
Veins: Carry blood to heart

Q

Conduction

A

Electric current in the heart that causes the myocardium to contract
average heart rate is 60-90 bpm
SA(sinoatrial) pacemaker of the heart
systole: contraction of ventricles

pressure exerted by the blood against the wall of an artery/vein
written as a ratio
normal systolic = 90-140
normal diastolic =60-90
mesures in mm/Hg
