Increasing muscle mass requires more energy, even for maintenance. Add the increased activity of weight lifting and your body is naturally burning more calories than if there is no weight training involved provided there isn't an increase the number of calories you eat per day.

The posterior descending branch of the right coronary artery usually supplies the inferior wall of the right ventricle. The acute marginal branches of the right coronary artery supply the anterior wall of the right ventricle, and the conus branch supplies the infundibulum of the right ventricle. A direct correlation exists between the anatomic site of right coronary artery occlusion and the extent of right ventricular infarction.
In essence, the left main coronary artery supplies the left atrium, interventricular septum, left ventricle and the anterior wall of the right ventricle. On the other hand, the right coronary artery supplies the right atrium, the right ventricle as well as the sino-atrial node. Interestingly, coronary blood flow can be described as a phasic flow.
