What is the Myocardium? - answer✔✔Muscle of the heart
Responsible for pumping
What is the Epicardium? - answer✔✔Exterior portion of the heart
What is the Pericardium? - answer✔✔2 layers that attach to epicardium and visceral pericardium
Space filled with fluid that lubricates heart during contraction
What does the diastolic value indicate? - answer✔✔Relaxation
This is the ventricular filling
What does the systolic value indicate? - answer✔✔Contraction
Atrial and ventricular systole not simultaneous
Atrial contracts at the end of diastole
Ventricular follows atrial systole
What happens in the R. atrium and ventricle? - answer✔✔Superior and inferior vena cava,
coronary sinus deliver blood to atrium
Deoxygenated blood carried to lungs via pulmonary artery

, What happens in the L. atrium and ventricle? - answer✔✔Distributes oxygenated blood to body
via aorta
Atrium receives oxygenated blood from pulmonary veins
What are the Atrioventricular valves? - answer✔✔Tricuspid and mitral / biscuspid valves
Where is the tricuspid located? - answer✔✔Separates the R. atrium and R. ventricle
Where is the Mitral / Bicuspid located? - answer✔✔Between the L. atrium and the L. ventricle
What happens to the AV valves during diastole? - answer✔✔Open and blood moves into
ventricles
What happens to the AV valves during systole? - answer✔✔Close to prevent regurg/back flow
What are the Semilunar valves? - answer✔✔Pulmonic and Aortic
Where is the Pulmonic valve located? - answer✔✔Between R. ventricle and pulmonary artery
Where is the Aortic valve located? - answer✔✔Between L. ventricle and aorta
What happens to the Semilunar valves during diastole? - answer✔✔They are closed
What happens to the Semilunar valves during systole? - answer✔✔Forced open when blood is
ejected from ventricles
What is cardiac output? - answer✔✔Amount of blood pumped by each ventricle in L per min
What is a normal cardiac output? - answer✔✔5 L/min
What is stroke volume? - answer✔✔Amount of blood ejected with each heartbeat
What is Preload? - answer✔✔Degree of stretch of cardiac muscle fibers at end of diastole
Diastole = ventricles full of blood = greater stretch
What is contractility? - answer✔✔Ability of cardiac muscle to shorten (contract) in. response to
electrical impulse
What is the equation for Cardiac Output? - answer✔✔SV x HR
Where do we get cholesterol and how is it used? - answer✔✔Sources are animal products and
synthesis by the liver
Where do we get Triglycerides and how are they used? - answer✔✔Correlate with LDL.
