When does the blood flows through the coronary artery during left ventricular systole or right ventricular systole?

Neither, theoretically the two ventricles contract simultaneously. The coronary arteries begin as two holes just above the leaflets of the aortic valve. During systole the leaflets block the coronary arteries and prevent blood flow to them. It is during diastole (of both ventricles) that blood returns to the coronary vasculature.

What is the cause of ventricular tachycardia?
Most ventricular tachycardias are associated with serious heart disease such as coronary artery blockage, cardiomyopathy, or valvular heart disease.
What structure supplies oxygenated blood to the heart muscle?
Coronary arteries. The orifice of the coronary arteries are located on proximal part of the ascending aorta, and there are two orifices branching into the left and right coronary arteries.The marginal, anterior and ventricular arteries provide the cardiac muscle with oxygenated blood.The coronary arteries are the major vessels bringing blood to the heart muscle. The are the left and right coronary arteries, the left having a common trunk followed by the circumflex and anterior descending branches. Each of these give off side branches which bring blood and hence oxygen to the heart muscle. Coronary arteries fill during diastole.There is a right coronary artery and the left coronary artery. In total there are four coronary arteries.
What artery runs along the coronary sulcus?
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
What is your heart doing when it is in systole?
Diastole is when a given chamber of the heart is relaxing. There is atrial diastole and ventricular diastole. Most of the time when talking about diastole we are referring to the ventricular because that is when we measure the diastolic (low) pressure in your systemic arteries, usually the brachial artery.
What is the shorter coronary artery that is hidden anterior by pulmonary trunk?
left coronary artery
The circumflex branch and the anterior inter-ventricular artery are branches of the?
Left coronary artery
Which artery supplies the anterior ventricular walls and laterodorsal part of the left side of the heart?
Left coronary artery
What is the name of the vein beginning at the apex of the heart and ascending in the anterior ventricular groove with the anterior ventricular artery?
coronary vein
When does most of coronary artery perfusion occur?
ventricular diastole after the aortic valve has closed.
How do you trace blood from the left coronary artery to the apex of the heart and back to the right atrium?
A person can trace the blood flow from the left coronary artery to the apex of the heart and to the right atrium, by following inter ventricular artery. Blood also will move through the pulmonary semi lunar valve.
What is the cause of ventricular tachycardia?
Most ventricular tachycardias are associated with serious heart disease such as coronary artery blockage, cardiomyopathy, or valvular heart disease.
What is the coronary artery's purpose?
to pump blood through out the heart

Is coronary artery the largest artery?
No. The coronary arteries are not the largest arteries. The aorta is the largest artery.
