Sample Questions from the A&P Key Terms 19 Cardiovascular S. Heart Key Terms

Question: anterior cardiac veins

Choices:

vessels that parallel the small cardiac arteries and drain the anterior surface of the right ventricle; bypass the coronary sinus and drain directly into the right atrium

Question: afterload

Choices:

force the ventricles must develop to effectively pump blood against the resistance in the vessels

Question: anterior interventricular sulcus

Choices:

sulcus located between the left and right ventricles on the anterior surface of the heart

Question: atrioventricular (AV) node

Choices:

clump of myocardial cells located in the inferior portion of the right atrium within the atrioventricular septum; receives the impulse from the SA node, pauses, and then transmits it into specialized conducting cells within the interventricular septum

Question: anastomosis

Choices:

(plural: anastomoses) area where vessels unite to allow blood to circulate even if there may be partial blockage in another branch

Question: artificial pacemaker

Choices:

medical device that transmits electrical signals to the heart to ensure that it contracts and pumps blood to the body

Question: anterior interventricular artery

Choices:

(also, left anterior descending artery or LAD) major branch of the left coronary artery that follows the anterior interventricular sulcus

Question: aortic valve

Choices:

(also, aortic semilunar valve) valve located at the base of the aorta

Question: atrioventricular bundle branches

Choices:

(also, left or right bundle branches) specialized myocardial conductile cells that arise from the bifurcation of the atrioventricular bundle and pass through the interventricular septum; lead to the Purkinje fibers and also to the right papillary muscle via the moderator band

Question: atrioventricular bundle

Choices:

(also, bundle of His) group of specialized myocardial conductile cells that transmit the impulse from the AV node through the interventricular septum; form the left and right atrioventricular bundle branches

Question: atrial reflex

Choices:

(also, called Bainbridge reflex) autonomic reflex that responds to stretch receptors in the atria that send impulses to the cardioaccelerator area to increase HR when venous flow into the atria increases
