they are on the surface of the heart, and there is three main ones the right coronary artery, the left one and the circumflex artery but they all have branches coming off. They are important because they are how the heart gets its oxygen and nutrients and as its such an important muscle it needs a good supply of oxygen to use in respiration to get energy or it can lead to people having heart attacks which are deadly, hope this helps :)
