 Facts  
  1. The skin is the body's largest and also the fastest-growing organ. Skin covers 22 square feet (2 square meters) of the human body in a full grown adult. (1.)
  2. The liver is the largest internal and most metabolically complex organ in humans. The liver performs over 500 different functions including fighting off infection, neutralizing toxins, manufacturing proteins and hormones, controlling blood sugar and helping to clot the blood. The liver is the only organ that can regenerate itself thus making it possible for one person to donate part of their liver to another person. When a portion of the liver is transplanted, the donor's liver will regenerate back to its original size while the transplanted portion will grow to the appropriate size for the recipient. (2.)
  3. The typical brain is about 2% of a body’s weight but uses 20% of its total energy and oxygen intake. Your brain is 73% water. It takes only 2% dehydration to affect your attention, memory and other cognitive skills. Twenty-five percent of the body’s cholesterol resides within the brain. Cholesterol is an integral part of every brain cell. Without adequate cholesterol, brain cells die. Researchers estimate that our brains contain roughly 86 billion brain cells. A piece of brain tissue the size of a grain of sand contains 100,000 neurons and 1 billion synapses all communicating with each other. (3.)
  4. Human lungs are the only organs that can float. The total length of the airways running through the two lungs is 1,500 miles or 2,400 kilometres. The two lungs together contain 300 to 500 million alveoli. Scientists estimate that the total internal surface area of lungs in adult humans vary between 30-50 sq. meters and 70-10 sq. meters. The total internal surface area of human lungs is estimated to be equal to the total area of one side of a tennis court. (4.)
  5. Your heart beats about 100,000 times, sending 2,000 gallons of blood surging through your body every day. A normal heart valve is about the size of a half dollar and generally speaking, a healthy heart is about the size of the person's fist. (5.)
