what makes up the endocardium
simple squamous epithelia
what makes up the fibrous pericardium
dense connective tissue
function of papillary muscles
close atrioventricular valves via chordae tendineae
function of trabeculae carneae
help with overall contraction
goes from heart to lungs and is deoxygenated
pulmonary circulation
goes from heart to body tissues and is oxygenated
systemic circulation
what makes the “lub” sound
closure of the atrioventricular valves during ventricular systole/ contraction
what makes the “dub” sound
closure of the semilunar valves during ventricular diastole/ relaxation
what does the p wave represent
atrial depolarization
what does the qrs complex represent
ventricular depolarization
what does the t wave represent
ventricular repolarization
what sound is represented with the qrs complex
lub
what sound is represented with the t wave
dub
chest pain due to inadequate heart muscle oxygenation
angina pectoris
large amounts of fluid inflame pericardial cavity, compressing the heart
cardiac tamponade
heart enlarges and pumping efficiency declines in a positive feedback look
congestive heart failure
accumulation of fatty acids on coronary arteries, narrowing or blocking them
coronary artery disease
often characterized by abnormal heart sounds
heart valve disorders
problems with av node/ bundle lead to ventricles not recieving pacing impulses. pacemaker used
heart block
left ventricle has thick walls, leading to high pulmonary blood pressure
hypertrophic cardiomyopathy
oxygen-starved cardiac cells die leading to heart attack
myocardial infarction
enlargement/ failure of right ventricle due to hypertension in pulmonary circuit
pulmonary arterial hypertension
