sphygm/o pulse
steth/o chest
varic/o swollen, twisted vein
ventricul/o swollen, twisted vein
atrium upper right or left chamber of the heart
interatrial septum partition between the right and left atria
interventricular septum partition between the right and left ventricles
visceral pericardium layer of the pericardium closest to the heart (visceral = pertaining to organ)
parietal pericardium outer layer (parietal=pertaining to wall)
ventricle lower right or left chamber of the heart
aortic valve heart valve between the left ventricle and the aorta
mitral valve heart valve between the left atrium and the left ventricle (cuspis = point); also called the bicuspid valve
bicuspid valve heart valve between the left atrium and the left ventricle (cuspis = point); also called the mitral valve
pulmonary valve heart valve opening from the right ventricle to the pulmonary artery (luna = moon); also called the pulmonary semilunar valve
arteries vessels that carry blood away from the heart to the arterioles
aorta large artery that is the main trunk of the arterial system branching from the left ventricle
capillaries tiny vessels that join arterioles and venules
venules small vessels that gather blood from the capillaries into the veins
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
blood pressure (BP) measure of the blood within the systemic arteries maintained by the force and rate of the heartbeat and the diameter and elasticity of arterial walls; measured with a sphygmomanometer (blood pressure cuff) for diagnostic purposes
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
saccular aneurysm a sac-like bulge on one side of an artery
fusiform aneurysm a spindle-shaped bulge of an artery
angina pectoris chest pain caused by a temporary loss of oxygenated blood to heart muscle; often caused by narrowing of the coronary arteries (angina = to choke)
arteriosclerosis thickening, loss of elasticity, and calcification (hardening) of arterial walls
atherosclerosis a form of arteriosclerosis characterized by the buildup of fatty substances that harden within the walls of arteries a swollen area within the lining of an artery caused by the buildup of fat (lipids)
claudication limping; pain in a limb (especially the calf) while walking that subsides after rest; caused by inadequate blood supply
heart murmur an abnormal sound from the heart produced by defects in the chambers or valves
