The Cardiovascular System Flashcards
(250 cards)
heart; receives blood from the veins and pumps blood into the arteries
card/o, cardi/o
blood vessels; transport blood to and from all areas of the body
angi/o, vas/o
arteries; transport blood away from the heart to all parts of the body
arteri/o
capillaries; permit the exchange of nutrients and waste products between the blood and the cells
capill/o
veins; return blood away from all body parts to the heart
phleb/o, ven/o
blood; brings oxygen and nutrients to the cells and carries away waste
hem/o, hemat/o
pertaining to the heart and blood vessels
cardiovascular
hollow, muscular organ located in the thoracic cavity between the lungs
heart
lower tip of the heart
apex
(pericardial sac) double-walled membranous sac that encloses the heart
pericardium
pertaining to membrane, which is a thin layer of pliable tissue that covers or encloses a body part
membranous
fibrous sac that surrounds and protects the heart
parietal pericardium
found between the two layers of the pericardium, where it acts as a lubricant to prevent friction as the heart beats
pericardial fluid
inner layer of the pericardium that also forms the outer layer of the heart (epicardium)
visceral pericardium
external layer of the heart and the inner layer of the pericardium
epicardium
the middle and thickest layer of the heart’s three layers
myocardium
consists of specialized cardiac muscle tissue that is capable of constant contraction and relaxation that creates the pumping movement necessary to maintain the flow of blood throughout the body
myocardial muscle
consists of epithelial tissue, is the inner lining of the heart; comes into direct contact with the blood as it pumps
endocardium
supply oxygen-rich blood to the myocardium
coronary arteries
two upper chambers of the heart, divided by the interatrial septum; receive blood
atria
two lower chambers of the heart, divided by the intraventricular septum
ventricles
controls the opening between the right atrium and the right ventricle; 3 cusps, points
tricuspid valve
located between the right ventricle and the pulmonary artery
pulmonary semilunar valve
(bicuspid valve) located between the left atrium and the left ventricle; means shaped like a bishop’s mitre (hat)
mitral valve
