| coron/o | circle or crown |
| phleb/o | vein |
| sphygm/o | pulse |
| steth/o | chest |
| varic/o | swollen, twisted vein |
| endocardium | membrane lining the cavities of the heart |
| epicardium | membrane forming the outer layer of the heart |
| interatrial septum | partition between the right and left atria |
| interventricular septum | partition between the right and left ventricles |
| pericardium | protective sac enclosing the heart composed of two layers with fluid between |
| visceral pericardium | layer of the pericardium closest to the heart |
| parietal pericardium | outer layer |
| heart valves | structures within the heart that open and close with the heartbeat to regulate the one-way flow of blood |
| aortic valve | heart valve between the left ventricle and the aorta |
| valves of the vein | valves located at intervals within the lining of veins, especially in the legs, which constrict with muscle action to move the blood returning to the heart |
| arterioles | small vessels that receive blood from the arteries |
| capillaries | tiny vessels that join arterioles and venules |
| systemic circulation | circulation of blood throughout the body via arteries, arterioles, capillaries, venules, and veins to deliver oxygen and nutrients to body tissues |
| coronary circulation | circulation of blood through the coronary blood vessels to deliver oxygen and nutrients to the heart muscle tissue |
| pulmonary circulation | circulation of blood from the pulmonary artery through the vessels in the lungs and back to the heart via the pulmonary vein, providing for the exchange of gases |
| diastole | to expand; period during the cardiac cycle (complete heart beat) when blood enters the relaxed ventricles from the atria |
| systole | to contract; period during the cardiac cycle (complete heart beat) when the heart is in contraction and blood is ejected through the aorta and the pulmonary artery |
| normotension | normal blood pressure |
| hypotension | low blood pressure |
| hypertension | high blood pressure |
| polarization | resting; resting state of a myocardial cell |
