Coronary Circulation - Arteries
The Left Coronary Artery
- (a. coronaria cordis sinistra), larger than the right, arises from the left anterior aortic sinus
- divides into an anterior descending and a circumflex branch
- there is a free anastomosis between the minute branches of the two coronary arteries in the substance of the heart
- anterior descending branch
- passes at first behind the pulmonary artery
- then comes forward between that vessel and the left auricula
- to reach the anterior longitudinal sulcus
- descends along to the incisura apicis cordis
- gives branches to both ventricles
- circumflex branch
- follows the left part of the coronary sulcus
- running first to the left and then to the right
- reaching nearly as far as the posterior longitudinal sulcus
- gives branches to the left atrium and ventricle
