- ANSWER mediastenum, just behind the sternum 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 arteries in the body that carry oxygenated blood? - ANSWER pulmonary arteries (efferent) 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 what is the purpose of heart vavles? - ANSWER to prevent the backflow of blood therby assuring uni-directional flow through the heart what are the subdivisions of the heart valves? - ANSWER Atrioventricular valves (AV): Tricuspid + Bicuspid Mitral semilunar valves: Pulmonic + Aortic What are the AV cuspid valves characteristcs? - ANSWER have tough fibrous rings, long and strong leaflets (cuspids), accessory organs (ie papillary muscles, chordae tendinae) give the location of the AV cuspid valves? - ANSWER tricuspid is btw the right atrium and right ventricle, bicuspid mitral is btw left atrium and left ventricle characteristics of semilunar valves? - ANSWER three leaflests, shallow in depth, no accessory organs give location of semilunar valves? - ANSWER pulmonic btq right ventricle and pulmonary trunk, aortic btw left ventricle and aorta where are the coronary arteries located? - ANSWER on the epidcardium what are the two branches of the left coronary artery? - ANSWER Left anterior descending (LAD) artery and Left Circumflex (LCX) artery what is the main artery that supplies the right side of the heart? - ANSWER Right Coronary Artery (RCA) What is the period of contractions of both atria and ventricles? - ANSWER systole what is the period of relaxation and filling of all cardiac chambers? - ANSWER diastole heart sounds are caused by what? - ANSWER closure of the heart vavles when does the S1 first heart sound (Lubb) occur? - ANSWER occurs during ventricle contraction and closure of AV valves when does the S2 second heart sound (Dupp) occur? - ANSWER occurs during ventricular relaxation when SL valves close heart murmurs are caused by what? - ANSWER diseases of the valves or other structural abnormalities define heart rate - ANSWER number of heart contractions per minute what two things control heart rate? - ANSWER chemo-receptors (chemical sensors) and Baro-receptors (pressure receptors) located in the aortic arch and carotid arteries 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 how is the electricity created by pacemaker cells? - ANSWER elecrtical impulses created by passing of ions through the cell membrane What are the 4 properties of cardiac cells? - ANSWER automaticity excitability conductivity contractility [Show More]
