| Term | Definition |
|---|---|
| lining of the heart | endocardium |
| partition between right and left ventricles | ventricular septum |
| fibroserous saclike structure surrounding the heart | parietal pericardium |
| two chambers of the heart that contain deoxygenated blood | right atrium and right ventricle |
| large artery that carries blood from the right ventricle | pulmonary artery |
| blood vessel that returns blood to the heart from head and arms | superior vena cava |
| rhmnant of a functional prenatal vessel between the pulmonary artery and the aorta | ligamentum arteriosum |
| structure formed from ductus arteriosum | ligamentum arteriosum |
| valve at the base of the pulmonary artery | pulmonic semilunar valve |
| two arteries that are branched of the pulmonary artery | left pulmonary artery and right pulmonary artery |
| synonym for bicuspid valve | mitral valve |
| structure on the cardiac wall to which the chordae tendineae are attached | papillary muscle |
| muscular portion of cardiac wall | myocardium |
| thin covering on the surface of the heart (2 names) | epicardium and visceral pericardium |
| large vein that empties blood into the top of the right atrium | superior vena cava |
| two chambers of the heart that contain oxygenated blood | left ventricle and left atrium |
| chamber of the heart that receives blood from the lungs | left atrium |
| large artery that carried blood out from the left ventricle | aorta |
| large vein that empties blood into the lower part of the right atrium | inferior vena cava |
| atrioventricular valves | bicuspid valve (mitral valve) and tricuspid valve |
| valve at the base of the aorta | aortic semilunar valve |
| blood vessel in which openings to the coronary arteries are located | aorta |
| atrium into which the coronary sinus empties | right atrium |
| valvular restraints that prevent the atrioventricular valve cusps from being forced back into the atria | chordae tendineae and papillary muscles |
| two principal branches of the left coronary artery | anterior interventricular artery and circumflex artery |
| coronary vein that lies in the anterior interventricular sulcus | great cardiac vein |
| coronary artery that lies in the right atrioventricular sulcus | right coronary artery |
| vein that receives blood from the great cardiac vein | coronary sinus |
| vein that lies in the posterior interventricular sulcus | posterior interventricular vein |
| two major coronary arteries that take their origins in the wall of the aorta | left coronary artery and right coronary artery |
| large coronary vessel that empties into the right atrium | coronary sinus |
| coronary vein that parallels the right coronary artery in the right atrioventricular sulcus | small cardiac vein |
| branch of the right coronary artery on the posterior surface of the heart | posterior descending right coronary artery |
| vein that lies alongside of the posterior descending right coronary vein | middle cardiac vein |
