coronary circuit of blood through the heart

Off the aorta is the right coronary artery which then turns-divides into the Right Marginal Artery and the Posterior Interventricular Artery. Then the Left Coronary Artery turns into-divides into the anterior Interventricular artery and then the circumflex artery. Returning blood from the heart comes from the Great Cardiac Vein, the Middle Cardiac Vein and the Small-lesser Cardiac Vein. All draining into the coronary sinus located on the back of ther heart and then deoxygenated blood is returned to the right atrium.

I studied the blood flow through the heart by running on a treadmill at Gold's gym and repeating the above over and over again. This class motivated me by realizing just because I feel and look healthy on the outhside I really was'nt on the inside. I know that I have high
Cholesterol which is a soft, waxy substance found among the lipids (fats) in the bloodstream and in all your body's cells. It's an important part of a healthy body because it's used to form cell membranes, some hormones and is needed for other functions. But a high level of cholesterol in the blood — hypercholesterolemia — is a major risk factor for coronary heart disease, which leads to heart attack. After learning of the blood flow through the heart and just how important it is to keep it running as smooth as possible I have been watching what I eat and running three days a week.
