The process of getting better.
Process of restoring health or normal function or of natural repair of damaged or cut tissue.
The act or process through which a person regains the normal structural and functional characteristics of health and well-being after an illness or injury.
The process through which the body restores and heals bone, tissue, or organ damage caused by injury, infection, or disease.
The initial stages of healing are consistent throughout the body. Following an injury, blood clots form in the damaged tissues. White blood cells, enzymes, histamine, and other chemicals, along with proteins that aid in the generation of new cells, accumulate at the site of damage. Fibrous tissue is then formed within the blood clot, providing a supportive structure, while dead cells are broken down and absorbed by the white blood cells. In certain tissues like bone and skin, new cells multiply around the damaged area, facilitating regeneration. For skin injuries, the fibrous tissue contracts as new skin forms underneath. Eventually, the tissue hardens to create a scab, which falls off once the new skin growth is complete. Although a scar may remain, the body’s healing process is crucial in restoring damaged bone, tissue, or organ functions.
Insufficient blood supply or persistent infection can hinder tissue regeneration. Some tissues, like nerve tissue, may be incapable of regenerating. In such instances, fibrous tissue might evolve into durable scar tissue, maintaining the tissue structure but potentially affecting its function.
