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.
Like other muscles, it needs oxygen and nutrients to function. The heart receives its oxygen and nutrients from blood pumped from a large blood vessel called the aorta, through smaller blood vessels called arteries (coronary arteries), then through even smaller vessels called arterioles and capillaries.ike other muscles, it needs oxygen and nutrients to function.
