Solution

endothelium- composed of simple squamous epithelium

coronary artery-supply blood to myocardium

common carotid artery-carry blood to the head

anterior cerebral artery-carry blood to frontal and parietal lobes

celiac trunk- a branch of the abdominal aorta

vertebral vein- drains blood from spinal cord and neck
