Phases of Wound Repair
8.0K
Following injury, the integrity of the injured tissues must be reestablished. For example, in skin tissue, wound repair involves coordination among resident skin cells, blood mononuclear cells, extracellular matrix, growth factors, and cytokines to complete the healing cascade.
Formation of Blood Clot
In case of deep injuries, trauma to blood vessels results in blood loss. In the meantime, phospholipids released from the ruptured endothelial cellular membrane are converted into arachidonic...

Healing I: Introduction
14
Healing is the physiological process by which the body restores the integrity and function of damaged tissues following injury. It involves a coordinated interplay of cellular proliferation, extracellular matrix remodeling, and growth factor signaling. The extent and nature of the tissue damage determine whether healing occurs by resolution, regeneration, or replacement.ResolutionResolution represents the most complete form of healing, occurring when the injury is minimal and tissue...

Healing II: Complications
37
Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...
