Question | Answer |
---|---|
Describe capillaries. | Join arterial system with venous system. Most significant of blood vessels. Provide cells with vital products. Remove waste products from cells. |
Describe the heart. | Hollow, muscular organ lying in the mediastinum that propels blood to entire body. |
Describe the SA (sinoatrial) node | Located in upper portion of right atrium. Has built-in rhythm. Initiates and transmits each heart beat. Sets basic pace for cardiac rate. |
How do veins return blood to the heart? | skeletal muscle contraction. gravity. respiratory activity. valves. |
How is blood supplied to the heart muscle? | coronary arteries |
Name the factors that influence blood pressure. | resistance of blood flow. pumping action of heart. viscosity of blood. elasticity of arteries. quantity of blood. |
Name the four structures responsible for electrical conduction of the heart. | SA node AV node bundle of His Purkinje fibers |
Name the three layers of the heart. | Endocardium Myocardium Epicardium |
What are the three layers of artery walls? | tunica externa tunica media tunica intima |
What are the three major types of blood vessels? | arteries capillaries veins |
What are valves? | Small structures within veins that prevent backflow of blood. |
What is endocarditis? | Inflammation of the inner lining of the heart and its valves. |
What type of blood do arteries carry? | oxygenated |
What type of blood do veins carry? | deoxygenated |
Where is each heart valve located? | Tricuspid- right ventricle and right atrium Pulmonic- pulmonary arteries and right ventricle Bicuspid (aka) Mitral- left atrium and left ventricle Aortic- aorta and left ventricle |
angioplasty | any endovascular procedure that reopens narrowed blood vessels |
cardioversion | applying controlled electrical shock to the exterior of the chest |
deep vein thrombosis | blood clot that forms in the deep veins of the body |
thrombosis | blood clot that obstructs a vessel |
bicuspid valve | blood passed from the left atrium to the left ventricle; aka mitral valve |
pulmonary artery | carries deoxygenated blood from the right ventricle to the lungs |
pulmonary vein | carries oxygenated blood back to the heart from the lungs |
beta-blockers | causes a decrease of heart rate and contractility |
inferior vena cava | collects and carries deoxygenated blood from the lower portion to the right atrium |
superior vena cava | collects and carries deoxygenated blood from the top portion to the right atrium |

pericardium | fibrous sac which encloses the heart |
atherosclerosis | form of arteriosclerosis characterized by deposits of plaque in arteries |
arteriosclerosis | hardening and narrowing of an artery |
arrhythmia | inability of the heart to maintain a normal sinus rhythm |
insufficiency | inability of the valves to close properly |
valvotomy | incision of a valve to increase the size of the opening |
diuretics | increase excretion of water and sodium |

coarctation | narrowing of a vessel |
infarction | necrosis of tissue following cessation of blood supply |
epicardium | outermost layer of the heart |
cardiac catheterization | passage of a catheter into the heart |
pulmonic valve | prevents backflow of blood into the right ventricle |
laser ablation | procedure used to remove or treat varicose veins |
palpitation | sensation that the heart is not beating normally |
