How Does Regeneration Work in Biology

Would not it be wonderful if people who have lost arms or legs, or just a finger in an accident, could simply grow a new one? This, unfortunately, when it comes to people, it is not possible, but there are living beings in whom it is possible. The process by which living organisms updated structure or sometimes even whole organs is called regeneration.

Among living beings regeneration is quite different. For example, in some types of worms and sea starfish, a tiny fraction of the body can restore the entire organism. Even if it is only a small part, will grow a whole new body.

On the other hand, we have a kind of regeneration that occurs in our own body. The surface layer of our skin is constantly waste in the form of small particles and is replaced by other cells. Our hair and nails are refurbished. Even our permanent teeth are an example of regeneration. In animals there is change of feathers, fur or shells, which are replaced with new ones in the process of regeneration.

As is a complex organism, and man has a very complex organism, it is his ability to regenerate smaller. The man, like other mammals, can not renew a single body as a whole. But, lizards and insects can regenerate whole limbs. Regeneration in humans is actually a repair of damage, such as broken bones, skin injuries and some types of nerves.

Did you know; the liver is an amazing organ because it can be regenerated even if it has been damaged by more than 50 percent.

Regeneration is performed in two ways. In the first case, a new tissue grows from the surface of the wound. In the other remaining parts are changed and reorganized, but does not create a new material.

When grows new material (such as limbs), it grows in this way. Bud of regeneration is created on the surface of the wound. It is usually conical in shape and contains an embryonic type of cells or cells such as those of the birth of that living being. These cells can develop into cells specially designed for the construction of a new body, and they are growing, and new body is gradually created.
