Epicardium - ANSWER Inner membrane on the surface of the heart muscle
Myocardium - ANSWER Cardiac Muscle
Pericardium - ANSWER Outer membrane (sac around the heart)
Serous fluid - ANSWER Is between the parietal and visceral layers; prevents friction as the heart beats
Parietal Membrane - ANSWER Middle layer
What lines the myocardium? - ANSWER Epicardium which prevents abnormal clotting
Vena Cava - ANSWER 1st
Right Atrium - ANSWER 2nd
Tricuspid Valve - ANSWER 3rd
Right Ventricle - ANSWER 4th
Pulmonic Valve - ANSWER 5th
Pulmonary Artery - ANSWER 6th
Lungs - ANSWER 7th
, Pulmonary Veins - ANSWER 8th
Left Atrium - ANSWER 9th
Mitral Valve - ANSWER 10th
Left Ventricle - ANSWER 11th
Aortic Valve - ANSWER 12th
Aorta - ANSWER 13th
Rest of the body - ANSWER 14th
What part of the heart pumps with the most force? - ANSWER Left ventricle
SA Node (Sinoatrial) - ANSWER Pacemaker initiates heartbeat at about 100 beats per minute and 75 at
rest (even lower for athletes)
AV Node - ANSWER Backs up the SA node at 40-60 beats per minute
Bundle of His - ANSWER Backs up the AV node by stimulating the left ventricle to beat at a rate of 25-35
beats per minute
During a cardiac cycle how does the atria and ventricle's contract? - ANSWER The atria contract
simultaneously and then the ventricles contact simultaneously (about a half a second later)
S1 "lubb" - ANSWER Closure of the AV valves during ventricular systole
