I know the circumflex artery supplies the left atrium.... but cannot find ANYWHERE in my text book... what supplies the RIGHT ventricle with blood. I need to be able to cite the source of your answer... I would like to know anyhow if you do know.... but if i am going to debate this with my professor I need to be able to defend my answer. PLEASE HELP

The RIGHT CORONARY ARTERY supplies oxygenated blood to the walls of the RIGHT VENTRICLES and the RIGHT ATRIUM.
Remember that in CORONARY CIRCULATION, CORONARY ARTERIES mainly function in carrying oxygenated and nutrient filled blood to the heart muscles. It has only two branches which are:
>>Right Coronary Artery which supplies oxygenated blood to the walls of the right ventricles and the right atrium.
>>Left Main Coronary Artery which DIRECTS oxygenated blood to the left anterior descending artery and the left circumflex.
===>>The Left Anterior Descending Artery then supplies oxygenated blood to the ANTERIOR walls of the left ventricles and the left atrium (front region of the heart).
===>>While the Left Circumflex Artery supplies oxygenated blood to the POSTERIOR walls of the left ventricles and the left atrium (back region of the heart).

What a confusing question. It sounds like you are talking coronary arteries and if your text book does not have a detailed diagram of the heart and the coronary arteries it is a pretty lame book. The RCA arises from the Right Coronary cusp of the Aorta and continues down the coronary sulcus. The first branch is the conus and the second branch is the SA nodal (very important because this feeds the pacemaker of the heart). The RV is fed via the acute marginals and the posterior descending artery. Also the circumflex does much more than feed the LA it also feed the posterior portion of the LV. What are you planning on debating with the professor? If it is the lameness of the text book, you may have a good case.
For future reference get a good book with alot of illustrations like Grey's anatomy.

The right coronary artery along with the sinoatrial nodal artery supplies the right atrium with oxygenated blood

The arteries carries blood away from the heart, veins carry blood to the heart. From the body to the heart (deoxygenated) (vein) From the heart to the lungs (deoxygenated)(artery) From the lungs to the heart (oxygenated) (vein) From the heart to the body (oxygenated) artery) Artery under high pressure as the heart pushes it away, veins under low pressure after the capillaries step pressure down.

are you asking right atrium or right ventricle? your bold question says right atrium, yet in your details you ask about the right venticle. Please clarify.
If you're talking right venticle, then that would be due to the SA node and the tricuspid valve. If you're talking right atrium, that would be due to the superior vena cava.
Arteries don't supply the heart with blood. Arteries take blood AWAY from the heart (i.e. aorta) Veins bring it back.
