Coronary Arteries :

Question Answer
What is the opening that feeds blood to the coronary arteries?The Coronary Ostium
Where is the Ostium located?In the Aorta near the Aortic Valve
During what pumping phase is the Ostium closed?Systole- when the aortic valve is partially closed due to blood pumping through it.
During what pumping phase, is the Ostium open?Diastole- When the Left Ventricle is filling with blood, and the Aortic Semi-lunar valve is closed
What is another name for the Left Coronary Artery?The Left Main Artery
Name the areas of the heart that the RCA supplies blood toRight Atrium, Right Ventricle, and part of the Inferior and Posterior surfaces of the left ventricle
Name the electrical impulse fibers that the RCA supplies blood tothe SA node in 50% of the population, Bundle of His and the AV node
What two major branches does the LCA split into?Left Anterior Descending and Left Circumflex
What are the two branches of the Left Anterior Descending Artery?The Septal Ferforators and the Diagonal Arteries
What areas do the Branches coming off of the LAD provide blood for?The Walls of both Ventricles
Name the areas that the LAD supplied blood to?Anterior surface of the Left Ventricle, Intraventricular Septum
Name the electrical impulse fibers that the LAD supplies blood toRight Bundle Branch, and Left Anterior fasciculus of the left bundle branch
What areas does the Circumflex Artery supply blood to?Lateral walls of the Left Ventricle, the Left Atrium, and in 50% of the population the SA node.
Name the electrical impulse fibers that the Left Circumflex supplies blood toIn 50% of the population, the SA node.
Name the two arteries that could possibly supply blood to the Sinoatrial (SA) node RCA and Left Circumflex Artery
What vessel returns deoxygenated blood from the myocardium to the Right Atrium?The Coronary Sinus

Physiology of the heart

Question Answer
What is Cardiac Output?The amount of blood heart pumps in a minute
What is normal cardiac output?4 to 8 Liters per minute
How do you figure Cardiac Output?By multiplying Heart Rate x Stroke Volume
What is stroke volume?The amount of blood ejected with each ventricular contraction
What are the 3 factors that affect stroke volume?Preload, Afterload, and Myocardial Contractility
