It allows deoxygenated blood from the heart muscles to get back to the chambers of the heart to continue in the circulatory system.
The coronary veins drain into the coronary sinus, which in turn drains into the right atrium.

Coronary veins have oxygen rich blood. Hope I helped (:no, they carry deoxygenated blood to the coronary sinus.
the coronary arteries feed oxygenated blood to the heart muscle where as the coronary veins take the deoxygenated blood back the heart.
The coronary system is comprised of arteries, arterioles, capillaries, venules and veins. From the innumerable cardiac capillaries, blood flows back to the cardiac chambers through venules, which in turn coalesce into the cardiac veins. Most cardiac veins collect and return blood to the right atrium through the coronary sinus; there may or not be a Thebesian valve covering the ostium of the coronary sinus. The major venous vessels of the human heart are: coronary sinus, the anterior interventricular veins, left marginal veins, posterior veins of the left ventricle, and the posterior interventricular veins (see also the Coronary System Tutorial).
To drain the tissues of the heart and empty into the coronary sinus
atrium
In the lower right side of the heart. when the heart pumps it causes the coronary veins to pump outward.
The function of the coronary arteries and veins is to supply the heart with vital oxygen for it to function. It may also carry trace minerals that help it conduct and contract.
The coronary circulation provides blood to the heart's tissues. The coronary circulation includes the coronary arteries and coronary veins.
Coronary arteries and veins are found on the surface of the heart, branching out across the myocardium (muscle tissue of the heart). The coronary arteries supply oxygen-rich blood to the heart muscle, while the coronary veins collect oxygen-depleted blood from the heart muscle and return it to the circulation.
