These arteries are NOT part of systemic circulation.
What are pulmonary arteries (or cardiac arteries)?
100
Heart muscle is also called this.
What is myocardium?
100
The medical term for the death of heart cells that die when deprived of oxygen.
What a myocardial infarction?
100
One of two ways venous return of blood to the heart is enhanced.
What are valves in veins or muscular movement?
200
The blood pressure is most likely to be highest in these vessels.
What are arteries?
200
One of the following does NOT increase cardiac output: sympathetic stimulation to the heart, exercise, fever, parasympathetic stimulation to the heart.
What is fever?
200
The crushing pain felt when the myocardium is deprived of oxygen.
What is angina?
200
Pulmonary arteries carry (oxygenated / deoxygenated) blood to the lungs.
What is deoxygenated?
300
This is the dense connective tissue covering the heart.
What is the parietal pericardium?
300
Of these major vessels--inferior vena cava, superior vena cava, coronary sinus, and pulmonary vein--the one that carries oxygenated blood.
What is the pulmonary vein?
300
Cardiac muscle is enclosed by this double sac of serous membrane.
What is the pericardium?
300
Heart rate slower than 60 beats per minute.
What is bradycardia?
400
This part of the heart is at the bottom of the ventricles and at the level of the fifth intercostal space.
What is the apex?
400
Of the following vessels--capillaries, vena cava, arterioles, pulmonary artery--this one is likely to have the largest the lumen (inside space).
What is the vena cava?
400
The partition of the heart between the ventricles and where the bundle branches are located.
What is the (introventricular) septum?
400
Heart rate greater than 100 beats per minute.
What is tachycardia?
500
These are vessels which connect arterioles to venules.
What are capillaries?
500
The muscle tissue of the heart that receives stimulus from the Purkinje fibers.
What is the myocardium?
500
Unusual heart sounds which may indicate valve or heart wall imperfections. Often heard in children or the elderly.
