Wound Classification and Healing Processes Quiz

Laceration involves tearing of skin and underlying tissues.

The inflammatory phase removes debris and bacteria from the wound site.

Primary intention healing occurs when wound edges are closely approximated with minimal tissue loss.

Collagen Type I provides tensile strength to the wound during the maturation phase.

The inflammatory phase involves the removal of necrotic tissue and debris from the wound.

Platelets form a temporary seal to stop bleeding and initiate clotting.

Angiogenesis occurs during the proliferative phase.

An incision is characterized by a clean and straight cut.

Fibroblasts produce collagen during wound healing.

Collagen fibers become more organized and cross-linked during the maturation phase.

Macrophages remove debris and bacteria during wound healing.

Granulation tissue promotes angiogenesis and tissue repair during wound healing.

Protease enzymes degrade fibrin during the remodeling phase of wound healing.

Myofibroblasts contract the wound during the healing process.

Secondary intention healing occurs when the wound is left open and heals through the formation of granulation tissue.

A keloid is an overgrowth of scar tissue.

Vitamin C is essential for collagen synthesis.

The wound contracts and reduces in size during the maturation phase.

Myofibroblasts produce collagen and contract the wound.

PDGF plays a crucial role in promoting cell migration and tissue repair.

A contusion involves damage to skin and underlying tissues without breaking the skin surface.

Low oxygen levels may contribute to impaired collagen synthesis in delayed wound healing.

An incision is caused by a sharp object, resulting in a clean and straight cut.

Fibroblasts mainly produce collagen during the proliferative phase of wound healing.

A laceration is caused by a sharp object, resulting in a jagged and irregular cut.
