In many organs of the body, the thymus have been neglected by people for long time, until the occurrence of one thing, people begin to look at it with new eyes. At that time, a new born baby in UK was suffering from a mysterious disease, children repeated infection after birth, without any resistance, and finally he was diagnosed as congenital thymus agenesis. Then the doctor conducted thymus implantation to him, which is that doctors from a miscarriage fetus remove a living thymus to implant to the abdominal muscles of the sick infant, as the result, it turned out to be a miracle, children survived healthily. It brought interest to researchers. Later, scientists from various countries made unremitting efforts and finally see the “true colors” of the thymus. The thymus is the little glands located in human pleural mediastinal top, or behind sternum, and its growth and development is slow; when people are born, it is only the size of a walnut, and weighs approximately 20 grams; when people reach 15 years old, at best, the weight is 35 grams; to 25 years old, it will rapidly decline; until 40 years old, it is like the size of a peanut, and then it only has a little trace to be found. Therefore, thymus has been considered to be gradual degradation of the tissue, and it is about to be discharged by the body. After studying, scientists found that the thymus is a “special forces training center” in the human body to fight the invasion of external pathogenic substances. We live in a not clean environment full of germs and pollution, the reason why we can be safe in most of the time; it is to rely on the protection of the “special forces.” However, this “Special Forces” are the lymphocytes with immune function. In which, the largest number, the most efficient, and the most powerful is T lymphocytes and B lymphocytes. They not only can directly kill the bacteria, viruses and cancer cells which invade in vivo, but also has ability to recognize and remember. No matter how pathogenic substances are disguised, no matter how often bacteria come, they can kill all of them. At the same time, it also can cause the body to produce enough antibodies to enhance the human body and disease resistance. However, this force is not born. These lymphocytes turned out to be non-functional, but later with the blood flow to reach the thymus, affected by the thymic hormone secreted by the thymus, they became a well-trained team, and play full role of immune function through thymus. Well, a person without thymus from birth, his life will not exceed infancy. Most players play online games for fun and they almost play every day. So the gold is used up soon, they have to buy in Guild Wars 2 Gold, Guild Wars 2 Gold and Guild Wars 2 Gold Sale.
