anastomosis | of blood vessels may be perfomed to bypass an occluded area and remove normal blood flow to the area |
aneursym | localized dilation of a weakened area of the wall of an artey. The weakened area ballons out with every pulsation of the artery |
aneurysmectomy | surgical removal of the sac of an aneurysm |
anomaly | deviation from nomral; birth defect; for example congential anamaly |
anorexia | lack or loss of appetite, resulting in the inability to eat. is seen in indviduals who are depressed, with the onset of fever and illness with the stomach disorders or a result of excessive intake of alochol or drugs |

ascites | an abnormal collection of fluid within the peritoneal cavity(the peritoneum is the serous membrane that lines the entire abdnominal cavity) this fluid contianas large amounts of protein and electrolytes. gernal abdmonial swelling occurs with ascites |
atherosclerosis | a form of arteriosclerosis (hardening of the arteries)characterized by fatty deposits building up within the inner layers of the walls of larger arteries |
hepathomegaly | enlargement of the liver |
epicardium | the inner layer of the pericardium, which is the double-folded membrane that encloses the heart |
endocarditis | inflammation of the inner lining of the heart |
edema | the localized or gerneralized collection of fluid within the body tissues,causing the area to swell |
dysrhythmia | abnomral rhythm |
diastole | the period of relaxiation of the heart, alternating with the contraction phase is known as systole |
dependent edema | a fluid accumaltion in the tissues influenced by gravity, usually greater in the lower extermities than in tissue levels above the heart |
cusp | any one of the small flaps on the valves i=of the heart |
cornary artery | one of a pair of arteries that branch from the arota. the cornary arteries and their branches supply blood and oxygen to the heart muscle(myocardium) |
claudication | cramplike pains in the calves of the legs caused by poor circulation to the muscles of the legs;commonly assocaiated with artherosclerosis |
carditis | inflammantion of the heart muscles |
bruit | an abnormal sound or murmur heard when listening to a cartoid artery, organ or gland with a sethoscope for example during ausculation |
benign | noncancerous; not progressive |
nocturia | urination at night |
occlusion | closure, or state of being closed |
orthopena | an abnormal condition in which a person sits up straight or stands up to breathe comfortably |
pacemaker | the SA mode (sinoatrial) of the heart located in the right atrium. it is responsible for initiating the heartbeat, influencing the rate and rhythm of the heart beat |
the cardiac pacemaker | (artifical pacemeaker) is an electric apparatus used for maintaining a normal heart rhythm by eclectically stimulating the heart muslce to contract |
palpable | detectable by touch |
prophylatic | an agent that protects against disease |
palpiation | a pounding or racing of the heart, associated with normal emotional reponses or with disorders |
perciaridal | pertaining to the pericardium |
pericardium | the dounle membranous sac that encloses the heart and the origins of the great blood vessels |
petechiae | small. purplish, hemorrhagic spots on the skin; may be due to abnormality in the blood-clotting mechanism of the body |
pitting edema | is swelling, usually of the skin of the extremities, that when passed firmly with a finger will maintain the dent produced by the finger |
pulmonary artery | one of a pair of arteries that transports deoxygentaed blood from the right ventricle of the heart to the lungs for oxygenation. the pulmonary arteries are the only arteries in the body to carry deoxygenated blood |
pulmonary circulation | the circulation of deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation and back to the left artium of the heart; that is,from the heart, to the lungs, back to the heart |
Homan's Sign | pain felt in the calf of the leg, or behind the knee, when the examiner is purposely dorsiflexing the foot of the patient(bending the toes upward toward the foot) if the patient feels pain,it is called a positive Homan's sign(indicating thrombophlebitis |
hyperlipidemia | an excessive level of fats in the blood |
hypertension | elevated blood pressure persistently higher than 135/85 mmHg;high blood pressure;also known as arterial hypertension |
hypotension | low blood pressure;less than normal blood pressure reading |
infarction | a localized area of necrois (death)in tissue,a vessel,an organ,or a part resulting from a lack of oxygen(anoxia)due to interrupted blood flow to the area |
ischemia | decreased supply of oxygenated blood to a body part or organ |
lesion | a wound,injury or any pathological change in body tissue |
lipid | any of a group of fats or fatlike substance found in the blood. examples within an artery,vein,acids, triglycerides |
lumen | a cavity or the channel within sn y organ or structure of the body, the space within an artery,vein,intestine or tube |

murmur | a low-pitched humming or fluttering sound, as in a "heart murmur" heard on ausculation |
myocardium | the middle muscular layer of the heart |
pulmonary vein | one of the four larger veins(two from each lung)that returns oxygenated blood from the lungs back to the left atrium of the heart.the pulmonary veins are theonly veins in the body to carry oxygenated blood |
SA node | sinoatrial node;pacemaker of the heart |
septum | a wall,or partition, that divides or separates two cavities. the interatrial septum separates the right and left atria, the atrioventricular septum separates the atria and the ventricles & the interventricular septum separates the right & left ventricles |
