In addition, a 17 monitor uses another 80 watts. That comes to 150 watts in an hour, or .15 kWh. If you have the same computer on for only 4 minutes (say, to check your e-mail), that would come to .01 kWh.
A Dr. Mehmet Oz, MD , Cardiology (Cardiovascular Disease), answered. The heart gets its own supply of blood from the coronary arteries. The two main coronary arteries (right and left) and their branches supply blood throughout the heart muscle. This animation explains how these arteries transport blood.
Your heart requires its own system of blood and oxygen, which is supplied through a network of vessels known as the coronary arteries. These vessels originate at the aorta and run across the surface of the heart. The right coronary artery supplies blood to the right side of the heart and to a portion of the back side.wo of the major vessels off the left main coronary artery are the left anterior descending (LAD) and the circumflex. The LAD provides blood and oxygen to the front of the heart and to the bulk of its muscle tissue, while the circumflex supplies the left wall and part of the back of the heart.
