Heart Flashcards
Posterior aspect of heart
2/3 left atrium, 1/3 right atrium, a bit of left ventricle
T5-T8 vertebrae
Receives pulmonary veins (4)
In front of esophagus
Base
Inferior aspect of heart
2/3 left ventricle, 1/3 right ventricle
Diaphragmatic
Left atrium
Receives pulmonary veins
If dilated, can compress esophagus - dysphagia
Right atrium
Receives SVC and IVC, coronary sinus, anterior cardiac veins
Smooth = sinus venarum with foams voalis
Rough = pectinate muslce
Crista terminals separaties along SVC and IVC
Opening of coronary sinus is inferior
Anterior aspect of heart
Suspectible to trauma
Mostly right ventricle and left ventricle, some of right atrium (auricle)
Sternocostal
Triangle of Koch
Inferior part of right atrium
Contains AV node, opening of coronary sinus, septal leaflet of right AV valve
SA node
Junction of SVC and crista terminals of right atrium
Pacemaker
Tricuspid valve
Cordae tendinae link it to papillary muscles
Anterior, posterior and septal
Between right atrium and ventricle
Right ventricle
Rough = trabeculae carneae
Smooth = conus arteriousus
Moderator band
Right ventricle
Contains right AV bundle (near septal papillary muscle)
Pulmonary trunk
Divides into right and left
Right divides into superior and inferior
Left atrium
Receives blood from pulmonary veins (4)
Pectinate muscles and sinus venarum
Left ventricle
Trabaculae carnae, conus arteriosum
Aortic vestibule leads to aortic valve
Thicker wall
Bicuspid valve
2 papillary muscles - anterior and posterior
AKA mitral
Lub
AV valves closing
Dub
Semilunar valves closing (aortic and pulmonary)
