Pericardium

✓✓~ The outermost layer of the heart

Epicardium

✓✓~ this is the visceral layer of the heart and it lays directly over the heart and contains the
coronary arteries




Parietal layer

✓✓~ Layer of the heart above the epicardium and underneath the fibrous pericardium




Left ventricle

✓✓~ -This ventricle is the larger of the two because its workload is greater

-This ventricle pumps blood to the entire body and has a much higher afterload to

push against

-This makes the pressure in this side of the heart greater than the other side




Right ventricle

✓✓~ -This ventricle only pumps blood into the lungs

-The pressure in this side of the heart is lower than the other side




Umbilical vein

✓✓~ This receives oxygenated blood from the placenta
