wound healing

Wound Dressing

A material used to cover and protect a wound, promoting the healing process.

Acute Wound

A wound that usually heals within a few days and is not expected to become chronic.

Chronic Wound

A wound that does not heal in a timely manner, often lasting longer than 7 days.

Inflammation Phase

The initial phase of wound healing where the body reacts to injury, involving hemostasis and immune response.

Proliferation Phase

The phase of wound healing characterized by tissue formation, angiogenesis, and re-epithelialization.

Remodeling Phase

The final phase of wound healing where tissues strengthen and mature, which can take months.

Local Factors

Factors that affect wound healing within the direct vicinity of the wound, such as infection and oxygenation.

Systemic Factors

Factors affecting healing that are related to the overall health of the individual, such as age and nutrition.

Hemostasis

The process of stopping bleeding, crucial in the inflammatory phase of wound healing.

Angiogenesis

The formation of new blood vessels, important for providing nutrients and oxygen to healing tissues.

Reactive Oxygen Species (ROS)

Chemically reactive molecules containing oxygen, important in the inflammatory response.

Biofilms

A structured community of bacteria that form a protective barrier, complicating wound healing.

Hydrogel Dressings

Moist dressings that maintain hydration and provide a non-stick protective layer for wounds.

Alginate Dressings

Dressings made from seaweed that absorb exudate and promote a moist healing environment.

Epidermis

The outermost layer of skin, crucial for protecting underlying tissues.

Dermis

The layer of skin below the epidermis that contains connective tissue, hair follicles, and glands.

Hypodermis

The deepest layer of skin, composed of fat and connective tissues.

Stem Cells

Undifferentiated cells capable of giving rise to different cell types, important for tissue regeneration.

Healing Mechanism

The biological processes involved in tissue repair and regeneration after injury.

pH in Wound Healing

The acidity or alkalinity of the wound environment, which can affect the healing process and microbial growth.
