hematology/cardiology anatomy 2 (pink)

pericardium (layer of heart)

outer layer (connective tissue sack around heart)

myocardium (layer of heart)

muscle tissue that contracts to make heart beat

endocardium (layer of heart)

inner, epithelial layer

atria (L and R) chamber of heart

stretchy, recceive and hold blood returning to heart

ventricles (L and R) chambers of heart

muscular, pump blood from heart

septum (heart structure)

wall between L and R sides of heart

apex (heart structure)

point at inferior pole of heart

atrioventricular (AV) heart valve

allow from atria to ventricles, prevent backflow, tricuspid and bicuspid

seminular valve (heart valves)

Pulmonary (R) Aortic (L)

venae cavae (vessel)

superior, inferior, flow into R atrium

Pulmonary trunk and arteries (vessels)

R ventricle to lungs

Pulmonary veins (vessels)

lungs to left atrium

Aorta (vessels)

L ventricle to systemic arteries

Aortic sections

ascending, arch, descending (thoratic and abdominal aorta)

Coronary arteries (coronary circulation)

carry blood to myocardial cells

cardiac veins (coronary circulation)

return blood from myocardial cells

Coronary sinus (coronary circulation)

behind R atrium, collects returning blood

Pulmonary circuit

R atrium, triscupid valve, R ventricle, seminular, trunk and arteries, lungs (capillaries), veins

systemic circuit

L atrium, bicuspid (mitral) valve, L ventricle, aortic seminular valve, aorta, systemic arteries, capillaries, veins, vena cava

systole (heart beat)

contraction of heart, blood ejected

diastole (heart beat)

relaxation of heart, blood collected

ejection fraction (heart beat)

portion of hearts contents which leaves the heart w each beat

conduction

SA node, AV node, bundle of His, bundle branches, purkinje fibers

electrocardiogram

P-wave, QRS complex, T-wave

systolic (blood pressure) 110/70

during contraction

diastolic (blood pressure)110/70

during relaxation
