Cardiovascular System Flashcards
(18 cards)
Systole
closing of mitral and triscupid
heard best at apex
S1 (lub)
Diastole
closing of aortic and pulmonic valves
S2 (dub)
hear best at base
Hypertension more common?
men more than women until 45 yrs old
and people taking oral contraceptives
African Americans
Coronary artery disease
half of deaths of older people
Cardiac Risk factors (5)
nutrition smoking alcohol exercise drugs
APE To Man
aortic pulmonic erb’s point tricuspid mitral
PMI
over 6 is pulse deficit
Angina pectoris
chest pain due to ischemia of myocardium
more than 30min may indicate a myocardial infarction
Widow maker
left anterior descending artery clot
left atrium is most vital
left ventricle failure
blood backs up into left atrium into pulmonary capillaries
crackles
displaced apical pulse
right ventricle failure
backflow into inferior and superior vanea cavae
Thrombophlebitis
inflammation of vein that may or may not be with a clot
aneurysm
localized dilation of artery caused by weakness in arterial wall
abdominal aortic are most common
arteries
high pressure system
deeper in skin
elastic fibers and muscle fibers
each heartbeat creates a pressure wave which makes arteries expand and recoil
supply oxygen and essential nutritients to tissues
veins
more veins and lie closer to skin surface
low pressure system
drain deoxygenated blood and waste from tissues to heart
large diameter
efficient vanous return is dependent on skeletal muscles, competent vales in veins
Problems with venous flow
hypercoagulable states
dilated and tortuous (varicose) veins
genetic predisposition
arteriosclerosis
blood vessels grow more rigid with age
produces rise in systolic bp
atherosclerosis
a deposition of fatty plaque in the walls of the artery
