What do the semilunar valves do when the ventricles relax? - Answer The valves will close to prevent blood from flowing back into the ventricles. What arteries are in charge of supplying the heart with arterial blood? - Answer Coronary arteries; they deliver blood to the myocardium during diastole at a rate of 200-250 mL/min. Left coronary arteries carry about 85% of the blood & the right coronary arteries carry the rest. Left main coronary artery - Answer Supplies the left ventricle, the inter-ventricular septum, and part of the right ventricle. Right Coronary arter - Answer Supplies the right atrium and ventricle, part of the left ventricle, and the conduction system What is the purpose of the anastomoses connections? - Answer They play a key role in providing alternative route of blood flow in the event that one or more of the coronary vessels become blocked. acetylsalicylic acid - Answer AHA guidelines - Answer j - Answer
