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.
Together with the left anterior descending artery, the right coronary artery helps supply blood to the middle or septum of the heart. Smaller branches of the coronary arteries include: obtuse marginal (OM), septal perforator (SP), and diagonals.
