The coronary blood flow (ml per minute) is:
Correct Answer: 250
Description: Coronary blood flow per minute is 250ml/min, which represents approximately 4% of the normal resting cardiac output. Aerial coronary circulation supplies oxygenated blood to the myocardium through two major aeries the right and left coronary aeries. Myocardium receives largest poion of its blood flow during diastole. Coronary circulation very effectively extracts oxygen as blood flows through the capillary bed. Under resting conditions 60-70% of the available oxygen is extracted. Venous blood is returned to the atrium through the coronary sinus.
