Which organ uses 20% of the total oxygen in your body?

• Brain:The average adult human's brain accounts for about 2% of total body weight. Despite this relatively small size, about 20% of the body's oxygen supply is consumed by the brain. This organ's high metabolic rate remains almost constant despite fluctuations in motor activity and varying mental activity. The brain's metabolic activity largely results from oxidation of glucose into carbon dioxide and water. This chemical reaction results in the production of large amounts of energy. It doesn't matter whether you're resting or actively performing an activity. Source: PNAS.org
