right coronary artery

right above probe =probe in heart

right marginal artery

hanging artery on right side ( shaped

posterior interventricular artery

structure: inside posterior interventricular sulcus

left coronary artery

connects to pulmonary trunk, under probe

anterior interventricular artery

structure: inside anterior interventricular sulcus

circumflex artery

it follows down the anterior interventricular artery

1) right atrium 2) most of the right ventricle 3) part of the left ventricle 4) the SA and AV nodes

what does the right coronary artery supply

1) left atrium 2) part of the right ventricle 3) part of the right ventricle 4) interventricular septum

what does the left coronary artery supply

coronary sinus

internal structure: probe through thin skin

great cardiac vein

left lateral side shown from posterior side

middle cardiac vein

inferior to where coronary sinus is

fibrous pericardium

most external layer

parietal layer of the serous pericardium

(purple) outer layer

visceral layer of the serous pericardium

(green) directly on the heart; most internal

serous pericardium

(purple and green) collective

pericardial cavity

BQ ONLY: a potential space surrounding the heart between the parietal and visceral layers of serous pericardium

transverse pericardial sinus

BQ ONLY: behind the ascending aorta and pulmonary trunk- connects the left and right sides of the pericardial cavity

Endocardium

(green) inner most layer. traces inside

Myocardium

(purple) thick middle layer

Epicardium

(blue) outer most layer

interatrial septum

structure: pinching between two atriums

fossa ovalis

BQ: oval depression in the interatrial septum indicating the location of the fetal foramen ovale- where blood was shunted from right atrium to left atrium in the fetus
