simple it is an artery
the right interventricular sulcus I think it is atrioventricular sulus
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
Circumflex Branch
The Coronary Sinus
The left coronary artery
I believe it is the same as the coronary sulcus, or at least the coronary sulcus is one of the two AV sulci. If i am correct than it is the groove on the outside of heart, in which, the circumflex artery lies.
The atrioventricular sulcus or groove is where the right coronary artery lies. It is between the right atrium and the right ventricle.
anterior interventricular sulcus
It 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.
I can not to answer
Yes, the anterior branch of the left coronary artery, also known as the left anterior descending artery (LAD), courses within the anterior interventricular sulcus. This artery supplies blood to the anterior walls of the left ventricle and interventricular septum. It is a critical vessel for the heart's blood supply.
The Aorta, the coronary artery, the coronary vein, the inferior vena cava, the superior vena cava, the pulmonary artery.
