Circulation beyond heart

• what is coronary circulation

• what are the two main coronary arteries

• where do coronary arteries branch from

• circulation of blood that supplies the heart muscle with oxygen

• left coronary artery and right coronary artery

• the aorta

• function of coronary arteries

• what does the left anterior descending artery supply

• what does the left circumflex artery supply

• delivers oxygenated blood to the heart muscles

• the interventricular septum and anterior walls of the ventricles

• the atrium and posterior wall of the left ventricle

• what does the right posterior descending artery supply

• what does the right marginal artery supply

(need to know for cath lab)

• the posterior ventricular walls

• the right side of the heart

• function of cardiac veins

• what are the three cardiac veins

• what is the coronary sinus

• carry deoxygenated blood away from the heart muscles

• great, middle, small cardiac vein

• the three cardiac veins drain into the coronary sinus, then empties deoxygenated blood into the right atrium
