CORRECT
◉ how many times does the heart beat per minute? per day? Answer:
60-80 per minute
100,000 per day
◉ Four chambers of the heart Answer: right atrium, right ventricle, left
atrium, left ventricle
◉ The heart Answer: located in the thoracic cavity between lungs
-muscular pump made of cardiac muscle fibers
◉ septum Answer: wall that separates the heart into right and left sides
◉ pericardium Answer: outer double walled sac in the heart that
prevents friction allowing it to beat fast
◉ what are the three layers of the heart Answer: epicardium,
myocardium, endocardium
◉ endocardium Answer: Inner layer of the heart
,◉ Myocardium Answer: muscular, middle layer of the heart
◉ epicardium Answer: outer layer of the heart
◉ atria Answer: receives blood into the heart from the body
-contraction pushes blood into ventricles
-left and right atria separated by interatrial septum

vein

, ◉ which ventricle is bigger/thicker Answer: left because it has to pump
blood to the rest of the body
◉ cardiac cyle Answer: the complete sequence of events in heart from
the beginning of one beat to the beginning of the following beat
-includes systole and diastole
◉ cardiac output Answer: the volume of blood ejected from the left
ventricle in 1 minute (approx. 5 liters)
◉ stroke volume Answer: the volume of blood pumped from the left
ventricle in one beat

ventricle
◉ where does the right ventricle receive blood from? Answer: right
atrium
◉ where does the left atrium pump blood to? Answer: left ventricle
◉ where does the left ventricle receive blood from? Answer: left atrium
◉ How many heart valves are there? Answer: 4 tricuspid, bicuspid,
