Tissue injury refers to damage that occurs to cells and structures in the body due to various factors, such as physical trauma, chemical exposure, or infection. This damage can disrupt normal function and may lead to inflammation, pain, and other symptoms. Common types of tissue injuries include cuts, bruises, sprains, and burns. The body responds to tissue injury through a healing process that involves several stages, including inflammation, tissue formation, and remodeling. During inflammation, the body sends immune cells to the injured area to prevent infection and promote healing. Proper care and treatment are essential for optimal recovery and to minimize complications.
