pointed end of the heart
What is the apex?
100
phase of relaxation
What is diastole?
100
creates first heart sound
What is closure of the AV valves?
100
record of electrical activity of heart
What is an EKG or ECG?
200
heart chamber with the thickest myocardium
What is the left ventricle?
200
pacemaker of the heart
What is the SA node?
200
creates heart sounds
What is closure of valves?
200
carries deoxygenated blood away from heart to the lungs
What is the pulmonary artery?
200
volume of blood pumped by a ventricle in one minute
What is cardiac output?
300
wall between the ventricles
What is the interventricular septum?
300
consists of the epicardium, myocardium, and endocardium
What are the 3 layers of the heart wall?
300
name for one complete heartbeat
What is cardiac cycle?
300
muscle fiber in the ventricular tissue of the heart specialized for conducting an action potential to the myocardium
What are the conduction myofibers or Purkinje fibers?
300
medical term for heart attack
What is myocardial infarction?
400
sac enclosing the heart
What is the pericardium?
400
strands of connective tissue attaching valves to the papillary muscles
What are the chordae tendinae?
400
amount of blood leaving left ventricle with each contraction
What is stroke volume?
400
closes following ventricular systole
What are the semilunar valves?
400
lack of sufficient blood flow to the myocardium due to obstruction or constriction of a blood vessel
What is ischemia?
500
drains blood from the coronary circulation
What is the coronary sinus?
500
located between the parietal and visceral pericardiums
What is pericardial fluid?
500
the more the heart is stretched as it fills during diastole, the greater the force of contraction during systole

500
time when last 30% of blood enters ventricles
What is atrial systole?
500
compression of the heart by pericardial fluid
