Among the numerous mechanisms that make life possible, is the bodies ability to heal wounds and regenerate damaged tissue. The process begins as soon as an injury occurs.
Consider: The healing process is made possible by a cascade of complex cellular functions:
*Platelets adhere to tissues around a wound, forming a blood clot, and sealing damaged blood vessels.
* Inflammation protects against infection and removes any debris caused by the injury.
* Within days the body begins to repair injured tissue, making the wound contract, and repair damaged blood vessels.
* Finally, scar tissue remodels and strengthens the damaged area.
Inspired by blood clotting, researchers are developing plastics that can "heal" damage to themselves.Such regenerating materials are equipped with tiny parrallel tubes containing 2 chemicals that "bleed" when any damage occurs. As the 2 chemicals mix, they form a gel that spreads across the damaged areas, closing cracks and holes.
As the gel solidifies, it forms a tough substance that restores the materials original strength. One researcher admits that this synthetic healing process currently under development is "reminiscent" of what already exist in nature.
What Do You Think?
Did the body's ability to repair wounds come about by evolution?
or was it designed?
It. Doesn't. Matter.
