ch. 8 Flashcards
heart
The muscular pump that circulates blood through the heart, the lungs (pulmonary circulation), and the rest of the body (systemic circulation)
arteries
Branching system of vessels that transports blood from the right and left ventricles of the heart to all body parts; transports blood away from the heart
veins
vessels that transport blood from peripheral tissues back to the heart
capillaries
Microscopic blood vessels that connect arterioles with venules and facilitate passage of life-sustaining fluids containing oxygen and nutrients to cell bodies and removal of accumulated waste and carbon dioxide
blood
Fluid consisting of formed elements (erythrocytes, thrombocytes, leukocytes) and plasma. It is a specialized bodily fluid that delivers necessary substances to the body’s cells (oxygen, food, salts, hormones) and transports waste products (carbon dioxide, urea, lactic acid) away from those same cells. Blood is circulated around the body through blood vessels by the pumping action of the heart.

anastomosis
Connection of two things that are normally diverging, which can occur naturally in the body; however, in medicine an anastomosis typically refers to a surgical connection between blood vessels or the joining of one hollow or tubular organ to another
aneurysm
abnormal widening or ballooning of a portion of an artery due to weakness in the wall of the blood vessel
angina pectoris
chest pain that occurs when a diseased blood vessels restrict blood flow to the hear. it is the most common symptom of coronary artery disease (CAD) and is often referred to as angina
angioma
tumor of a blood vessel
angioplasty
surgical repair of a blood vessel or a nonsurgical technique for treating diseased arteries by temporarily inflating a tiny balloon inside an artery
angiostenosis
pathological condition of the narrowing of a blood vessel
arrhythmia
irregularity or loss of rhythm of the heart beat; also called dysrhythmia
arterial
pertaining to an artery
arteriosclerosis
pathological condition of hardening of arteries
arteritis
inflammation of an artery
artificial pacemaker
electronic device that stimulates impulse initiation within the heart. it is a small, battery operated device that helps the heart beat in regular rhythm
atheroma
tumor of an artery containing a fatty substance
atherosclerosis
pathological condition of the arteries characterized by the buildup of fatty substances and hardening of the walls
auscultation
method of physical assessment using a stethoscope to listen to sounds within the chest, abdomen, and other parts of the body
automated external defibrillator (AED)
Portable automatic device used to restore normal heart rhythm to patients in cardiac arrest. An AED is applied outside the body. It automatically analyzes the patient’s heart rhythm and advises the rescuer whether a shock is needed to restore a normal heartbeat. If the patient’s heart resumes beating normally, the heart has been defibrillated.
bicuspid
valve with two cusps; pertaining to the mitral valve
bradycardia
abnormally slow heartbeat defined as fewer than 60 beats per minute
bruit
pathological noise; a sound of venous or arterial origin heard on auscultation
cardiac
pertaining to the heart
cardiac arrest
loss of effective heart function, which results in cessation of functional circulation. sudden cardiac arrest (SCA) results in sudden death
cardiologist
physician who specializes in the study of the heart
cardiology
literally means study of the heart
cardiomegaly
enlargement of the heart
cardiometabolic syndrome (CMS)
A combination of metabolic dysfunctions mainly characterized by insulin resistance, impaired glucose tolerance, dyslipidemia (abnormally elevated cholesterol or fats in the blood), hypertension, and central adiposity (accumulation of fat around the abdominal area)
cardiomyopathy (CMP)
disease of the heart muscle that leads to generalized deterioration of the muscle and its pumping ability
cardiopulmonary
pertaining to the heart and lungs
cardiotonic
a class of medication that is used to increase the tone (pumping strength) of the heart
cardiovascular (CV)
pertaining to the heart and small blood vessels
cardioversion
Medical procedure used to treat cardiac arrhythmias. An electrical shock is delivered to the heart to restore its normal rhythm. The electrical energy can be delivered externally through electrodes placed on the chest or directly to the heart by placing paddles on the heart during an open chest surgery.
cholesterol
a normal, soft, waxy substance found among the lipids in the bloodstream and all body cells. It is the building block of steroid hormones, but it is dangerous when it builds up on arterial walls and can contribute to the risk of coronary heart diease
