Where do Coronary arteries fit in when you talk about blood flow?

i know that from the lungs the blood goes to the pul,pmary arteries to the left atrium and then through the atrioventricular valves and the to the left ventricle and then through the semilunar valve and then to the aorta then to the body cells but i don't know where the coronary arteries fit in to the direction of blood flow
