Cardiovascular System Answer: Delivers oxygenated blood to tissues and removes
waste products.
Heart Answer: A hollow muscular organ that pumps blood to all organs and body
tissues.
Autonomic system Answer: Controls how the heart pumps.
Vascular network Answer: Arteries and veins that carry blood throughout the body,
keep the heart filled with blood, and maintain blood pressure.
Valves Answer: Keep blood flowing in only one direction; healthy valves open and
close passively as a result of pressure changes in the heart chambers.
Atrioventricular valves Answer: Valves located between the atria and ventricles.
Semilunar valves Answer: Valves that prevent backflow from the arteries into the
ventricles.
Functions of the Heart Answer: The heart is a double pump divided into four chambers.
Cardiac cycle Answer: Transports blood through the lungs and to all the peripheral
tissues of the body.
Right side of the heart Answer: Responsible for pulmonary circulation.
Left side of the heart Answer: Responsible for systemic circulation.
Heart murmurs Answer: Swishing/blowing or unusually prolonged sounds indicative of
turbulent blood flow in the vascular system.
Causes of heart murmurs Answer: Regurgitation of blood through an incompetent
valve, blood flow in a dilated chamber, or increased blood flow through a normal valve.
Types of heart murmurs Answer: Innocent or physiological and abnormal or
pathological.
Lipid profile Answer: Measures the amount of cholesterol in the blood.
LDL Answer: "Bad" Cholesterol (builds up in arteries) < 70mg/dl optimal.
HDL Answer: "Good" Cholesterol; the higher the better.
Total Cholesterol Answer: < 200 mg/dl desirable.

, Creatine Kinase-MB Answer: Enzyme in cardiac muscle; elevates 4-6 hours after
cardiac tissue damage.
Troponin test Answer: Measures levels of proteins; these are detectable in 3-4 hours
and up to 7 days after myocardial damage.
Electrocardiogram (EKG) Answer: Provides vital information about the heart's electrical
conduction; used to diagnose abnormal heartbeats, heart rhythm, and tissue ischemia.
Echocardiography Answer: Ultrasound that helps diagnose cardiovascular disorders -
atherosclerosis, CHF, heart failure, aneurysm, enlarged heart, or shunting of blood.
Holter Monitor Answer: 24-hour cardiac electrical impulse monitor; records heart rate
and rhythm.
Exercise Stress Test Answer: Monitors heart function and rhythm while patient is
walking/running on a treadmill.
Question about heart pumping Answer: The heart is a double pump. The left atria
pumps blood to the left ventricle; the left ventricle pumps blood to the aorta.
Heart disease Answer: A range of conditions that affect the heart.
Rheumatic fever Answer: An inflammatory disease that can develop after a
streptococcal infection.
High blood pressure/hypertension Answer: A condition in which the force of the blood
against the artery walls is too high.
Elevated cholesterol levels Answer: Higher than normal levels of cholesterol in the
blood, which can lead to heart disease.
Diabetes Answer: A disease that occurs when your blood glucose, also called blood
sugar, is too high.
Heart attacks (myocardial infarction) Answer: A medical emergency where blood flow to
the heart is blocked.
Risk Factors for Cardiac Disease Answer: Factors that increase the likelihood of
developing heart disease.
Age Answer: Risk increases with age.
Sex Answer: Higher incidence in men than women until women reach menopause.
Family History Answer: A record of health conditions in family members that may
increase risk.
Race Answer: Certain racial groups may have higher risks for cardiac disease.
