Question | Answer |
The two upper chambers of the heart | atria |
carries blood from the lower body | inferior vena cava |
carries blood from the head and upper extremities | superior vena cava |
largest vein that drains the heeart | coronary sinus |
the right and left rides of the heart are sepreated by an internal call of connective tissue | septum |
seperates the right and left atria | interatrial septum |
two lower chambers of the heart | ventricules |
where is the base of the heart | top of the heart |
encircles the outside of the heart and seperates the atria from the venticles | sulci |
when the left heart is to recieve oxygenated blood and pump it out to the rest of the body | systematic circulation |
the right side of the heart is to pump unoxygenated blood to | pulmonary circulation |
which part of the heart is a high pressure pump? | left side |
addictional contribution of 30% blood resulting from atrial contraction | Atrial kick |
the amount of blood ejected from the venticle with each heartbeat. | stroke volume |
the percent of blood pumped out of a heart chamber with each contraction. normal is 50% | ejection fraction |
is a thin smooth layer of epithelium and connective tissue that lines the hearts inner chamber valves, chordae tendineae, and papillary muscles. | Endocardium |
is a thick layer that consists of cardiac muscle fibers (cells) responsible for the pumping action of the heart | myocardium |
is a double-walled sac that encloses the heart and helps protect it from trauma and infection | pericardium |
life threatening condidtion | cardiac tamponade |
a procedure in which a needle is inserted into the pericardial space and the excess fluid is sucked out (aspirated) through the needle | pericardiocentesis |
a membrane that covers smooth, stirated, and cardiac muscles | sarcolema |
energy -producing elements of a cell | mitochondria |
substances in intracardiac cells pass through broken cell membranes and leak into the blood stream | MI (myocardial infraction_ |
cardiac markers | tropin, creatine kinase, and myoglobin |
seperate the atria from the ventricles | antriventricular valves |
has two cusps, it lies between the left atrium and left venticle | mitral valves |
is the av valve that lies between the right strium and right ventricle (3 seperate cusps or flaps) | tricuspid valve |
are thin strands of connective tissues | chordae tendinae |
they are the pulmonic and aortic valves, that prevent back flow of blood from the aorta and pulmonary arteries into the ventricles | semilunar valves (sl) |
if a valve narrows, stiffens or thckens, the valve is said to be stenosed. the heart must work harder to pump blood through the stenosed valve | valvular stenosis |
if a valve flap inverts it is said to prolaps | valvular prolapse |
when does a heart sound occur? | because of vibrations in the tissues of the heart caused by the closing of the heats valve |
what are normal heart sounds called? | s1 and s2 |
name the 1st heart sound | "lubb" |
name the 2nd heart sound | "dubb" |
what is an abnormal heart sound called? |
