What occurs during the formation of granulation tissue?

1. It fills tissue defect with scar tissue

2. It leads to the necrosis of surrounding tissues

3. It causes immediate closure of the wound

4. It prevents the formation of new capillaries

The correct answer is: It fills tissue defect with scar tissue

Granulation tissue formation is a critical phase in the wound healing process characterized by the development of new connective tissue and tiny blood vessels. This tissue is essential as it fills in tissue defects during healing, replacing the temporary fibrin matrix with a more stable structure. As the tissue forms, it provides a framework that supports new capillaries, collagen, and cells necessary for healing, leading to the eventual restructuring of the wound area. This natural physiological process allows for better integration of the new tissue with the surrounding area, ultimately promoting the maturation and strength of the wound healing. The other concepts presented in the options mention processes that do not accurately reflect the granulation tissue formation phase. For example, the idea that granulation tissue leads to the necrosis of surrounding tissues contradicts the very purpose of this tissue, which is to promote healing and support recovery rather than damaging nearby tissues. Similarly, granulation tissue does not cause immediate wound closure; instead, it gradually fills the wound over time. Lastly, granulation tissue formation is characterized by an increase in angiogenesis (the formation of new blood vessels) rather than a prevention of capillary formation, highlighting its role in enhancing blood supply to the wound area to facilitate healing.
