Anatomy of the Heart

small depression in right atrium wall left over from fetal development

brings blood from surface of heart; small hole below I & S vena cava

connects valve to papillary muscles

holds onto chordae tendineae and connects to left and right ventricle

irregular muscular folds in ventricles

attaches pulmonary trunk to aortic arch

wall of tissue separating ventricles

small depression in right atrium wall left over from fetal development

brings blood from surface of heart; small opening below openings for superior and inferior vena cava

connects valve to papillary muscles

holds onto chordae tendineae and connects to left and right ventricle

irregular muscular folds in ventricles

attaches pulmonary trunk to aortic arch

come off base of ascending aorta on left side (not very visible on models)

wraps around heart towards posterior along separation of left atrium and left ventricle

goes down interventricular septum anteriorly

come off base of ascending aorta on right side and along separation of right atrium and right ventricle before splitting off into branches

goes down interventricular septum posteriorly

along middle of right ventricle vertically

large bulge on posterior side

travels up division between anterior interventricular septum then along separation of left atrium and left ventricle

travels up posterior interventricular septum

by marginal branch and along division of right atrium and right ventricle

first branch off of aortic arch

middle of three branches off of aortic arch

very left (or lateral) of three branches off of aortic arch; goes to left arm

branches off of brachiocephalic trunk to the left

branches off of brachiocephalic trunk to the right; goes to right arm
