Wound Healing

It is a process where fibroblast cells produce fibrous protein called collagen in the wound site when they enter thus, forming connective skin tissue to replace fibrin.

• Fibroblast deposition

• Collagen deposition

• Fibrin deposition

• Tissue deposition

These are differentiated cells that are responsible for the process of wound contraction.

• Keratinocytes

• Myofibroblasts

• Macrophages

• Platelets

This step of wound healing is not seen in primary intention. It is a response which functions to reduce the size of the tissue defect.

• Epithelial changes

• Process of granulation

• Inflammatory stage

• Wound contraction

It is a stage of wound healing where blood vessel is dilated and body sends immune cells to fight any pathogens that may have gotten through.

• Inflammation stage

• Remodeling stage

• Hemostasis stage

• Proliferative stage

It is a type of wound healing wherein the wound is surgically approximated only if it appears clean and has undergone a period of open observation.

• Healing by primary intention

• Healing by secondary intention

• Healing by tertiary intention

It plays a critical role in the formation of collagen, the growth of new capillaries, and the control of infection.

• Thrombocytes

• Neutrophils

• Oxygen

Extra connective tissue that forms within the original wound stays within that area

• Hypertrophic scars

• Keloid

• Pigmentation

• Excessive contraction

What is the fibrous protein produced by fibroblast cells in the wound site?

• Fibrin

• Collagen

• Keratinocytes

• Macrophages

What occurs during the proliferative stage?

• Epidermal cells divide to reform the outer layer of skin

• Dermis contracts to close the wound

• Newly deposited collagen is rearranged

• Blood vessels and connections are strengthened
