Chapter 11 Test updated Flashcards
drugs to dissolve clots are injected into the bloodstream of patients with coronary thrombosis
thrombolytic therapy
balloon-tipped catheter is inserted into a coronary artery to open the artery
percutaneous coronary intervention (PCI)
arteries and veins are anastomosed to coronary arteries to detour around blockages
coronary artery bypass grafting (CABG)
thin, flexible tube is guided into the heart via a vein or an artery
cardiac catheterization
echoes generated by high-frequency sound waves produce images of the heart
echocardiography (ECHO)
lipoproteins are physically separated are measured in a blood sample
lipoprotein electrophoresis
measurement of cholesterol and triglycerides in a blood sample
lipid tests
chemicals are measured in the blood as evidence of a heart attack
cardiac biomarkers
measurement of BNP in blood
BNP test
carry blood away from the heart
arteries
artery walls are lined with connective tissue, muscle tissue, and elastic fibers within an innermost layer of epithelial cells called…
endothelium
smaller branches of arteries
arterioles
allows oxygen and nutrients to be dropped off at body cells and the walls are very thin
capillaries
small veins
venules
prevents backflow of blood and keep the blood moving in one direction
valves
carries blood towards the heart
veins
blood flow from the heart to lung capillaries and back to the heart
pulmonary circulation
blood flow from the heart to tissue capillaries and back to the heart
systemic circulation
veins that carry oxygen-rich blood
pulmonary veins
artery that carries blood deficient in oxygen
pulmonary artery
arteries that supply CO2 to the heart muscle
coronary artery
upper chambers of the heart
atrium
lower chambers of the heart
ventricles
vein that drains blood from the upper portion of the body
superior vena cava
vein that carries blood away from the lower part of the body
inferior vena cava
thin-walled upper right chamber of the heart
right atrium
the right atrium contracts to force blood through the…and into the…
tricuspid valve
right ventricle
the lower right chamber of the heart
right ventricle
right ventricle contracts to pump oxygen-poor blood through the…
pulmonary valve
newly oxygenated blood enters..
the left atrium
left atrium contract to force blood through the….into the…
mitral valve
left ventricle
separates the two upper chambers
interarterial septum
separates the two lower chambers
interventricular septum
lines the interior of the heart and heart valves
endocardium
middle, muscular, thickest layer
myocardium
surrounds the heart
pericardium
when does systole occur
tricuspid and mitral valves closing as ventricles start to contract
when does diastole occue
pulmonic and aortic valves closing as ventricles begin to relax
heart rhythm
normal sinus rhythm (NSR)
largest artery in the body
aorta
specialized muscle fibers connecting the atria with the ventricles and transmitting electrical impulses between them
atrioventricular bundle (bundle of His)
specialized tissue in the wall between the atria
atrioventricular node (AV node)
specialized nervous tissue in the right atrium that begins the heartbeat
pacemaker
pacemaker of the heart
sinoatrial node (SA node)
instrument to measure blood pressure
sphygmomanometer
myx/o
mucus
phleb/o
vein
arterial anastomosis is called…
bypass
vas/o
vessel
treats delays and abnormalities in ventricular contractions
biventricular pacemaker
overcomes arrhythmias and keeps the heart beating at the proper rate
cardiac pacemaker
meds to treat fibrillation
anti-arrhythmics and anti-coagulants
most common septal defects
ventricular
right side heart failure
blood backs up into body
left side heart failure
blood backs into lungs and pulmonary edema
meds to treat heart failure
diruetic and digoxin
fluid accumulating in the lungs
pulmonary edema
chest pain at rest or chest pain of increasing frequency
unstable angina
vasodilator that increases coronary blood flow and lowers blood pressure
nitrates
reduces the force and speed of the heartbeat and to lower blood pressure
beta blockers
reduce high blood pressure and the risk of future heart attack even if the patient is not hypertensive
ACE inhibitors
catheterization with balloons and stents opens clogged coronary arteries
percutaneous coronary intervention (PCI)
backflow of blood into the left atrium
mitral regurgitation
vibration felt on palpation of the chest
thrill
murmur heard on auscultation
bruit
compression of the heart caused by collection of fluid in the pericardial cavity
cardiac tamponade
heard as a scraping or grating sound
pericardial friction rub
clot travels to the lung
pulmonary embolism
