pressure, heaviness, or tightness in the center of the chestArrhythmia:abnormal heart rhythmArteries:a major blood vessel that moves blood away from the heart out to the bodytissuesBlood:the fluid and its suspended formed elements that are circulated through theheart, arteries, capillaries, and veinsBlood types:inherited from one’s parents and determined by the presence orabsence of an antigen found on the surface of the red blood cellBlood vessels:vessels that convey blood; includes arteries, arterioles, capillaries,venules, and veinsCapillaries:microscopic blood vessel that connects arterioles with venulesCardiovascular:related to the heart and blood vesselsCerebrovascular Accident (CVA):complete or partial loss of blood flow to braintissue caused by blood vessel spasms, intracranial bleeding, and/or obstruction of theblood vessels in the brainCongestive Heart Failure (CHF):disease resulting from reduced blood flow from theheart; characterized by weakness, breathlessness, abdominal discomfort, and edemain the lower extremities.Coronary Artery Disease (CAD):a condition in which the arteries of the heart arenarrowed, affecting the supply of oxygen and nutrients to heart muscleElectrical conduction:muscle contractions occurring due to electrical conductionEmbolism:a mass (most commonly a blood clot) that travels through the blood andcan become lodged in a blood vessel and obstruct blood flowEndocardium:the innermost layer that lines the four chambers (two atria and twoventricles) and covers the valves of the heartErythrocytes:a red blood cell that transports oxygen and carbon dioxide to and frombody tissuesHeart chambers:four chambers, two upper (atria) and two lower (ventricles) throughwhich blood flows through the heartHeart murmur:abnormal sound heard during auscultation of the heart, such as a
