Question 1

Atrioventricular Valves

Answer 1

Valves that separate the atria from the ventricles.

Question 2

Bruit

Answer 2

A loud blowing sound, an abnormal finding, most often associated with a narrowing or stricture of the carotid artery usually associated with atherosclerotic plaque

Question 3

Bundle Branches

Answer 3

Expressways of conducting fibers that spread the electrical current through the ventricular myocardial tissue

Question 4

Bundle of His Atrioventricular Node

Answer 4

nodes that are intricately connected and function to receive the current that has finishes spreading throughout the atria

Question 5

cardiac conduction system

Answer 5

heart’s conduction system which can initiate and electrical charge and transmit that charge via cardiac muscle fibers throughout the myocardial tissue

Question 6

Cardiac Cycle

Answer 6

The events of one complete heartbeat, the contraction and relaxation of the atria and ventricles.

Question 7

Cardiac output

Answer 7

The amount of blood ejected from the left ventricle over 1 minute.

Question 8

Diastole

Answer 8

The phase of ventricular relaxation in which the ventricles relax and are filled as the atria contract.

Question 9

Electrocardiogram (EKG) Electrical representations of the cardiac cycle are documented by deflections on recording paper.
