angi/o

vessel

phleb/o

vein

endocardium

inside lining; lines chambers and valves

myocardium

thick muscular layer that makes up heart wall

epicardium

outside thin lining; covers heart

pericardium

surrounding fibrous sac

pulmonary circuit

right side to lungs, becoming oxygenated

systemic

left side; oxygenated blood to body

pulse

wave of increased pressure as ventricles contract

AV node

right atrium, passes impulses from SA node to ventricles

mitral valve

bicuspid valve; left AV valve

purkinje fibers

terminal fibers of conducting system of the heart, carry impulses through walls of ventricles

tricuspid valve

right AV valve

sinus rhythm

normal heart rhythm

aneurysm

localized abnormal dilation of a blood vessel

angina pectoris

feeling of constriction around the heart or pain may radiate to left arm or shoulder

arteriosclerosis

hardening of arteries, fatty deposits or calcium salts

atherosclerosis

development of fatty, fibrous patches in the lining of arteries, causing narrowing of lumen and hardening, form of arteriosclerosis

cerebrovascular accident

sudden damage to the brain resulting from reduction of blodo flow

clubbing

enlargement of ends of fingers and toes caused by growth of soft tissue around nails; poor peripheral circulation indicator

coarctation of aorta

localized narrowing on the aorta, restriction of blood flow

C reactive protein

during systemic inflammation, high CRP levels cardiovascular disease

deep vein thrombosis

thrombophlebitis involving deep veins

dissecting aneurysm

enters arterial wall and separates layers, usually aorta

dyslipidemia

disorder in serum lipid levels, important factor in development of atherosclerosis

edema

swelling of body tissues caused by presence of excess fluid

embolism

obstruction of a blood vessel by blood clot

embolus

mass carried in circulationf

fibrillation

spontaneous, quivering, and ineffectual contraction of muslce fibers

hemorrhoid

varicose vein in the rectum

ischemia

local deficiency of blood supply caused by obstruction of circulation

patent ductus arteriosus

persistence of ductus arteriosus after birth, connecting pulmonary artery to descending aorta to bypass the lungs

rheumatic heart disease

damage to heart valves after infection with a type of streptococcus

shock

circulatory failure resulting in inadequate supply of blood to tissues

stenosis

constriction or narrowing of opening

syncope

temporary loss of consciousness

stroke

cerebrovascular accident

varicose vein

twisted and swollen vein from breakdown of valves, pooling of blood, chronic dilation of vessel
