Question | Answer |
what encloses the heart, holds it in place | pericardium |
where is the fibrous pericardium | outer layer |
where is the parietal pericardium and visceral pericardium | inner/ double layer |
what is the outer layer. this is the visceral pericardium | epicardium |
what is the middle layer cardiac muscle (pumps) | myocardium |
what is the inner layer. squamous epithelium lines and covers valves | endocardium |
what is the upper chambers. separated by the interatrail septum | atria aka: atrium |
what is the lower chambers. separated by the inerventricular septum | ventricles |
what prevents blood from flowing backwards | valves |
what is found between atria and ventricles | atriocentricular |
what had 3 cusps (flaps) found b/w r. atrium and r. ventricle | tricuspid valve |
what has 2 cusps. found b/w l. atrium and l. ventricle | bicuspid valve |
what is found b/w ventricle and vessel leaving it | semilunar |
what is b/w r. ventricle and pulmonary truck | pulmonary valve |
what is b/w l. ventricle and aorta | aortic valve |
what is a threadlike structure that attaches the cusps | chordae tendineae |
what is arteries, capiliaries, veins that provide the myocardium w/ o2 and nutrients. blood drains back into the coronary sinus in the r. atrium | coronary circulation |
systole stands for what | contraction |
diastole stands for what | relaxation |
what is this atria contract while ventricles relax then ventricles contract while atria relax | coordination |
what is when ventricles contract, AV valves closing | lubb |
what is when ventricles relax, semilunars close | dubb |
what beats independently but CNS controls the rate | intrinsic |
what is behind r. atrium, acts like the human pacemaker | sinoatrial (SA node) |
what is near septum b/w atrium and ventricles | atriocentricular (AV node) |
what is inside top ventricular septum | bundle branches |
what is found throughout the ventricles | purkinje fibers |
what records changes in the cardiac cycle | electrocardiogram aka: ECK or EKG |
what wave SA node initiating systole of atria | p waves |
what wave Contraction of ventricles | QRS wave |
what wave Diastole (repolarization) of ventricles | T wave |
what is via spinal cord that stimulates by norepinophrine increase heart rate, strengthens contractions | sympathetic |
what is via vagus nerve that inhibited by acetylcholine, decreases heart rate, weakens contractions | parasympathetic |
what increase contractions | epinephrine |
what decreases contractions | high k+ or na+ |
what increase contractions- high | body temp |
what decreased contractions-older | age |
what decreased contractions-male | gender |
what lead away from | arteries |
what are small vessels | arterioles |
what are walls a single-cell-layer thick allow molecular exchange with cells | capillaries |
what collects blood from capillaries | venules |
what leads toward | veins |
what is normal blood pressure | 120/180 |
