Although it weighs only 2% of all our weight, the brain requires 15% of cardiac output and 20% of the total intake of oxygen into the body. More interestingly, a large amount of oxygen is still needed when the brain berisitirahat, and still not well known answer to the question, why the need is still there. To supply this need, it takes three main arteries, and if one of these traffic arteries, stroke is the definitive answer! In addition to energy, our brains also need a big skull and luxurious when compared with other limbs.
