Chapter 7 - Cardiovascular System Flashcards
State the flow of blood starting with the vena cava
(deoxygenated)inferior&superior vena cava –> Right Atrium –> tricuspid valve –> Right Ventricle –> Pulmonary Valve –> R&L Pulmonary Arteries –> Lungs –> (oxygenated) R&L Pulmonary Veins –> Left Atrium –> Mitral Valve –>Left Ventricle –> Aortic Valve –> Aorta –> Rest of Body
what is the function of the cardiovascular system?
to supply blood to all the tissues of the body
what’s another term for left atrioventricular valve?
mitral valve
what’s another term for right atrioventricular valve?
tricuspid valve
blood flow from the heart - rest of body - back to the heart
systemic circulation
blow flow from the heart - lungs - back to the heart
pulmonary circulation
partition that separates the right and left chambers
septum
contraction of the heart
systole
relaxation of the heart
diastole
double membrane sac that surrounds the heart
pericardium
heart muscle
myocardium
blood vessels that develop to provide an alternative route around an obstruction
collaterals
what are the layers of the heart from inside to outside
intima
muscular media
adventitia
most common congenital cardiac defect
atrial septal defect
allows shunting of blood from the high pressure left atria to the low pressure right atria
atrial septal defect
congenital narrowing of aorta
coarctation
accumulation of fatty material in a vessel
atherosclerosis
results in narrowing of the lumen
atherosclerosis
does atherosclerosis cause ischemia?
yes
chest pain resulting from mild ischemia
angina
what can atherosclerosis of the coronary arteries lead to?
MI(heart attack)
what is a lesion?
plaque plus a cap
can rupture and becomes highly thrombogenic
dilating an artery with a balloon&stent
angioplasty
