This gland controls growth, reproduction and the working of the endocrine glands. Some organs that never rest are the heart, the kidney and the lungs. Some organs that you can do without are tonsils and the appendix. The body's instant energy provider is the liver. It stores glycogen, which the body converts into glucose and burns to provide energy. The hardest substance of the body is the enamel of the teeth. A person can live a healthy life on one kidney and one lung. Two billion body cells wear out and are replaced everyday. The outermost layer of the skin is replaced every 15 to 30 days. Nerves carry messages at speeds up to 90m per sec. The small intestine is longer than the large intestine. They are 7mts. and 1. 5mts respectively. People who live in high altitudes have 2 liters more blood than those live in lower regions. By the time a man reaches 70, his heart would have pumped at least 174 million liters of blood and his kidneys would have removed wastes from more than 3.8 million liters of blood. The smile is the most frequently used facial expression. A smile can use anywhere from a pair of 5 to 53 facial muscles. The slowest growing finger nail is on the thumb nail and the fastest growing is the finger nail on the middle finger. The sensitivity of a woman's middle finger is reduced during menstruation.
