No need, the left coronary arises from the left posterior sinus of the ascending aorta.
no they are not connected.

The coronary sinus runs in the posterior coronary sulcus. In the anterior coronary sulci the stems of the coronary artery run. The circumflex branch of the left and the extension of the right coronary artery that becomes the posterior descending artery run around the coronary sulcus from front to back
The coronary arteries. These leave the aorta and branch out over the heart. Blood only flows though these vessels during diastole because during systole they are blocked off by the aortic valve. The two main vessels that arise from the Sinus of Valsalva, located just above the aortic valves, are the right and left cornary arteries. The right coronary artery mainly supply the right ventricle and the sinoatrial node. The left main artery is divided into the left anterior descending artery and the left circumflex artery. The left anterior descending artery mainly supplies the anterior and septal portion of the heart, namely the left ventricle. The left circumflex artery supplies the lateral walls of the left ventricle. Finally, the posterior descending artery can arise from either the right or left coronary artery. If the posterior descending artery arises from the right coronary artery, the heart is termed right heart dominant, which is seen in approximately 70% of individuals. If the posterior descending artery arises from the left circumflex artery, it is termed left heart dominance. It is also possible for the posterior descending artery to arise from both the right and left coronary artery. In this configuration, the heart is considered co-dominant. The posterior descending artery mainly supplies the inferior wall of the left ventricle and the inferior portion of the septal wall.
The Right Coronary Artery (RCA) supplies blood to the right atrium, right ventricle and the back of the septum. The main portion of the right coronary artery provides blood to the right side of the heart, which pumps blood to the lungs. The rest of the right coronary artery and its main branch, the posterior descending artery, together with the branches of the circumflex artery, run across the surface of the heart's underside, supplying the bottom portion of the left ventricle and back of the septum.
Left coronary artery
Left coronary artery.
The myocardium (muscle) that makes up the heart has its own blood supply called the coronary circulation. The coronary circulation comprises two main arteries; the left coronary artery and the right coronary artery. They branch off from the aorta (the biggest artery in the body!) really early on. The left coronary artery branches (into left marginal artery) to supply the left atrium and ventricle (chambers). The right coronary artery branches (into circumflex and left anterior descending) to supply the right atrium and ventricle and a bit of the left ventricle. Extra for experts: the way the coronary circulation is made up can change (just like people can be short or tall) because of genetic variability. So most people (about 70% off the top of my head) are "right dominant," because their right coronary artery branches to form the posterior interventricular artery. Some people are "left dominant" because their left coronary artery branches to form the posterior interventricular artery. So just remember Aorta --> left coronary artery --> left marginal --> right coronary artery --> circumflex + left anterior descending + the posterior interventricular artery from either left or right coronary artery Hope this helps :)

some times , after angiography the doctors says,this patient have two clogged arteries or three clogged arteries.My question,total how many arteries in normal human heart.and how many clogged arteries will lead the patient to death?
Which coronary artery is most likely occluded
It supplies the cardiac muscle with oxygen and other nutrients, but only the left side of the heart
