Med Term 6 & 12 Flashcards
Aortic
Valve between aorta and left ventricle
Aorta
Largest artery of the body
Oxygenated blood exits the heart
Arteriole
Tiny artery connecting to a capillary
Artery
Thick walled blood vessel
Carries oxygenated blood away from heart
Atrioventricular
Bundle of fibers in the inter ventricular septum
Transfers charges in the heart’s conduction system
His
Atrioventricular node AV
Specialized part of interatrial septum that sends a charge to the bundle of His
Atrioventricular valve
One of two valves that control blood flow between the atria and ventricules
Atrium
Either of the two upper chambers of the heart
Bicuspid
Atrioventricular valve on the left side of heart
Blood
Made of plasma
Circulates through body
Delivers nutrients
Blood pressure
Measure of the force of blood surging through arteries
Blood vessel
Any tubular passageways in cardiovacular system
Bundle of His
Atrioventricular bundle
Capillary
Smallest blood vessel
Exchange point between arterial and venous vessels
Carbon dioxide
Waste material transported in venous blood
Cardiac cycle
Repeated contraction and relaxation of heart as it circulates blood within itself and pumps it out to the rest of the body
Cardiovascular
Relating to or affecting the heart and blood vessels
Carotid artery
Artery that transports oxygenated blood to the head and neck
Conduction system
Part of the heart containing specialized tissue that sends electrical charges through heart fibers, causing the heart to contract and relax at regular intervals
Coronary artery
Blood vessel that supplies oxygen rich blood the heart
Depolarization
Contracting state of the myocardial tissue in heart’s conduction system
Diastole
Relaxation phase of heart beat
Ductus arteriosus
Structure in fetal circulatory system through which blood flows to bypass the fetus’s nonfunctioning lungs
Ductus venosus
Structure in the fetal circulatory system through which blood flows to bypass the fetal liver
