Questions and Answers

How does the healing process via secondary intention differ significantly from healing via primary intention?

Secondary intention is characterized by a faster healing time compared to primary intention.
Secondary intention relies on wound contraction, a process not seen in primary intention. (correct)
Secondary intention involves minimal tissue loss, whereas primary intention involves substantial tissue loss.
Secondary intention results in less prominent scarring compared to primary intention.

Which of the following best describes the role of granulation tissue in secondary intention wound healing?

It promotes rapid closure of the wound edges with minimal scar formation.
It primarily consists of dead cells and debris that hinder the healing process.
It prevents the formation of new blood vessels (angiogenesis) within the wound area.
It fills the wound space after significant tissue loss, supporting tissue regeneration. (correct)

What is the primary function of myofibroblasts during secondary intention healing?

To prevent collagen fiber deposition within the wound area.
To promote the breakdown of granulation tissue.
To initiate an intense inflammatory response by releasing bacterial toxins.
To facilitate wound contraction by pulling the wound edges together. (correct)

Flashcards

Secondary Intention

Healing process for wounds with significant tissue loss or widely separated edges.

Wound Contraction

Wound contraction that pulls the edges of the wound together, reducing its size.
