how many coronary arteries in the heart?
Question:
Answers:
There are three major coronary arteries. Two on the left (with a common trunk) and one on the right. They branch off from the aorta near the point where the aorta and left ventricle meet.
Other Answers:
ummmmm i think if that means chambers its 4?
There are 3 but they have a few branches off of them,
I believe that their are 4 or 6 but if you want the CORRECT number, consult a cardiologist. good luck
There are two(2)
The Coronary Arteries.—The Right Coronary Artery (a. coronaria [cordis] dextra) arises from the right anterior aortic sinus. It passes at first between the conus arteriosus and the right auricula and then runs in the right portion of the coronary sulcus, coursing at first from the left to right and then on the diaphragmatic surface of the heart from right to left as far as the posterior longitudinal sulcus, down which it is continued to the apex of the heart as the posterior descending branch. It gives off a large marginal branch which follows the acute margin of the heart and supplies branches to both surfaces of the right ventricle. It also gives twigs to the right atrium and to the part of the left ventricle which adjoins the posterior longitudinal sulcus. 5
The Left Coronary Artery (a. coronaria [cordis] sinistra), larger than the right, arises from the left anterior aortic sinus and divides into an anterior descending and a circumflex branch. The anterior descending branch passes at first behind the pulmonary artery and then comes forward between that vessel and the left auricula to reach the anterior longitudinal sulcus, along which it descends to the incisura apicis cordis; it gives branches to both ventricles. The 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; it gives branches to the left atrium and ventricle. There is a free anastomosis between the minute branches of the two coronary arteries in the substance of the heart.
the main ones are : left anterior descending, left circumflex, right coronary, diagonals, posterior descending artery and a few other smaller branches
