300 GM, 250GM
ORIENTATION OF HEART
LIES ON DIAPHRAGM, NEAR MIDLINE OF THORACIC CAVITY,2/3 LIE LEFT OF THE MIDLINE
APEX
TIP OF LEFT VENTRICLE WHICH LIES ON DIAPHRAGM AT 5TH INTERCOSTAL SPACE
BASE
POSTERIOR SURFACE OF HEART
ANTERIOR SURFACE OF HEART
DEEP TO STERNUM
INFERIOR/ DIAPHRAGMATIC SURFACE
BETWEEN APEX AND RIGHT BORDER RESTS MOSTLY ON DIAPHRAGM
RIGHT BODER
FACES RIGHT LUNG CONTAINS SVC IVC
LEFT BORDER AKA OBTUSE MARGIN
FACES LEFT LUNG, BASE TO APEX,
INFERIOR BORDER AKA ACUTE MARGIN
BETWEEN RIGHT BORDER AND APEX
ATRIOVENTRICULAR SULCUS
BETWEEN ATRIA AND VENTRICLES
ANTERIOR INTERVENTRICULAR SULCUS
BETWEERN LEFT AND RIGHT VENTRICLE ANTERIORALLY
POSTERIOR INTERVENTRICULAR SULCUS
BETWEEN LEFT AND RIGHT VENTRICLE ION THE POSTERIOR SURFACE.
coronary arteries
branch OFF ASCENDING AORTA AND ENCIRLE HEART LIKE A CROWN Branch into each other from
right coronary supplies
right atrium, most of RV, part OF LV (diaphragmatic), posterior 1/3 of septum, SA node (60%), AV node (80%)
left coronary supplies
left atrium most of LV part of RV ANTERIOR 2/3 SEPTU, SA NODE (40%)
LEFT CIRCUMFLEX
UNDER LEFT ATRIUM IN AV SULCUS
ANTERIOR INTERVENTRICULAR ARTERY AKA LAD
IN anterior IV SULCUS
CORANARY SINUS
LARGEST VEIN DRAING THE HEART DUMPS INTO RA
MIDDLE CARDIAC VEIN
BEGINS AT APEX ACENDS INTO POSTERIOR INTERVENTRICULAR SULCUS EMPTIES INTO CORONARY SINUS
