Study Notes
Coronary Blood Flow
- Arterial blood mostly enters the coronaries during diastole, when the aortic valve is closed and the heart muscle is relaxed.
- The entry of arterial blood into the coronaries primarily occurs during diastole.
- The main function of coronary circulation is to deliver oxygenated blood to the heart muscle.
Blood Vessels and the Heart
