FHP - Coronary Circulation, Heart Conduction & EKG Test

How does the heart get it's blood supply

• Aorta

• Vena Cavas

• Pulmonary Artery

• Coronary Arteries

• Coronary Veins

What are the two reasons that the heart can't get it's oxygen, carbohydrate and water supply just from the blood in it's chambers?

Why is it so critical that the 2 coronary arteries, the Right and Left coronary Arteries are located where they are in terms of system circulatioin?

Where is the opening for the Right and Left Coronary Artery Located

• At the base of the Aortic Arch at the opening of the Pulmonary Semilunar Valve

• At the base of the Aortic Arch at the opening of the Aortic Semilunar Valve

• At the Coronary Sinus where it drains into the Right Atrium

• At the Coronary Sinus where it drains into the Left Atrium

• At the base of the Pulmonary Veins, rich in oxygen where it drains into the Left Atrium

Within the Coronary Circulation system, where is deoxygenated blood delivered back to the heart

• Coronary Sinus at the Right Atrium

• Coronary Sinus at the Left Atrium

• Coronary Sinus at the Superior Vena Cava

• Coronary Sinus at the Inferior Vena Cava

• Coronary Sinus at the Pulmonary Semilunar Valve

The pacemaker of the heart is known as the

• SA Node - Sinoatrial Node

• AV Node - Atrioventricular Node

• AV Bundle or Bundle of His

• Purkinje Fibers

The node that delays the elecrical impulse in the heart is the

• SA Node - Sinoatrial Node

• AV Node - Atrioventricular Node

• AV Bundle or Bundle of His

• Purkinje Fibers

The node that serves as a "Relay Station" of the electrical impulse to the Ventricles is the

• SA Node - Sinoatrial Node

• AV Node - Atrioventricular Node

• AV Bundle or Bundle of His

• Purkinje Fibers

This part of the Heart Conduction System "Splits" the electrical impulse into right and left impulses

• SA Node - Sinoatrial Node

• AV Node - Atrioventricular Node

• AV Bundle or Bundle of His

• Purkinje Fibers

The Part of the Hearts electrical conduction system that causes the Atria to contract is the

• SA Node - Sinoatrial Node

• AV Node - Atrioventricular Node

• AV Bundle or Bundle of His

• Purkinje Fibers
