give layers of heart deep to superficial - ANSWER endocardium, myocardium, pericardium
what is the "heart skeleton" made of? - ANSWER four rings of thick connective tissue
what are the layers of fluid separating the parietal pericardium and visceral pericardium? - ANSWER pericardial sac
what structure in the middle of the heart divides the heart into two sides? - ANSWER septim
what kind of blood does the left and right side of the heart pump? - ANSWER right pumps deoxygenated blood w low pressure from veins into lungs (pulmonary circulation) and left pumps oxygenated blood with high pressure (blood pressure) toward the tissues through the arteries (systemic circulation)
What are the four heart chambers? - ANSWER right atrium, left atrium, right ventricle, left ventricle

what are the only veins in the body that carry oxygenated blood? - ANSWER pulmonary veins (afferent)
what is the largest artery in the body? - ANSWER the aorta
be familiar with heart anatomy - ANSWER

heart sounds are caused by what? - ANSWER closure of the heart vavles

the heart is under the influence of which nervous system? - ANSWER the autonomic nervous system which is subdivided into the sypathetic and parasypathetic
which division of the ANS has an inhibitory effect via acetylcholine? - ANSWER parasympathetic (vagus nerve)
what division of the ANS has a excitatory effect via norepinephrine? - ANSWER sypathetic
acetylcholine effects in body? - ANSWER slows SA pacemaker and heart rate, slows conduction of electricity in AV node, decreases strength of atrial and ventricular contraction
norepinphrine effects in body? - ANSWER increase HR, increases force of contraction, increases blood pressure, dopaminergic receptors increase the diameter of visceral blood vessels
True or false. the blood volume ejected outside the heart is equal to the blood volume returning back into the heart - ANSWER TRUE
what is stroke volume (preload)? - ANSWER the blood volume ejected outside the ventricle after each contraction; depends on volume of blood, force of myocardium contraction and vascular resistance
what is the Starling Law? - ANSWER the greater the volume of blood inside the heart during diastole, the stronger the heart contraction force during systole.
the lower the resistance in the vessels, the MORE OR LESS easily blood can be ejected outside heart through circulation? - ANSWER MORE
what is cardiac output? - ANSWER the amount of blood ejected outside heart per minute
cardiac output equals (X) * (Y) - ANSWER x- stroke volume
y- HRper/min
what is peripheral vascular resistance? - ANSWER the force exerted against the blood flow determined by diameter of the vessel; lower the vascular resistance the less force needed to eject blood
define blood pressure - ANSWER the force exerted by circulating blood volume on the walls of the artery during circulation
formula for BP - ANSWER BP equals (cardiac output) * (vascular resistance)
define EKG - ANSWER graphical presentation of heart electricity over time. electricity created by pacemaker cells
