Anatomy of Heart Flashcards
great vessels of the heart
pulmonary trunk, IVC/SVC, aorta
blood flow
SVC/IVC –> RA –> tricuspid valve –> RV –> pulmonary SL valves –> pulmonary artery –> lungs –> pulmonary vein –> LA –> bicuspid valve –> LV –> aortic SL valve –> aorta
red=ascending aorta lime green=right atria light blue=right ventricle pink=left ventricle yellow=left atria orange=pulmonary trunk blue=aorta
2 layers of pericardium
fibrous and serous
fibrous pericardium
tough external layer; non-dispensable
serous pericardium
smooth internal layer, split into parietal and visceral layers
parietal layer
lines inner surface of fibrous pericardium
visceral layer
technically the epicardium, lines surface of heart
pericardial cavity
space between parietal and visceral layers that contains lubricating fluid
4 surfaces of heart
anterior, left pulmonary, right pulmonary, and diaphragmatic
anterior surface of heart
formed by the right ventricle
left pulmonary surface of heart
formed by the left ventricle
right pulmonary surface of heart
formed by the right atrium
diaphragmatic/inferior surface of heart
formed by portions of LV and RV
coronary sulcus
separates atria from ventricles
