What type of tissue is expected to form during the proliferative phase of healing?

• A. Necrotic tissue
• B. Granulation tissue
• C. Scar tissue
• D. Epithelial tissue

Answer: (B)

The proliferative phase of wound healing is characterized by the formation of granulation tissue, which plays a crucial role in the healing process. During this phase, new blood vessels develop (angiogenesis) to supply nutrients and oxygen to the healing area, and fibroblasts, which are specialized cells, synthesize collagen and extracellular matrix that provide structural support. Granulation tissue appears pink or red due to the presence of these new blood vessels and is composed of a mixture of cells, including fibroblasts, macrophages, and newly formed capillaries. It serves as a scaffolding for the subsequent formation of new tissue and ultimately supports the process of wound closure. This choice is correct because granulation tissue is the hallmark of the proliferative phase, signifying that the wound is healing properly and moving towards closure. The other types of tissue mentioned, such as necrotic tissue, scar tissue, and epithelial tissue, do not accurately represent what occurs specifically during this healing phase. Necrotic tissue indicates tissue death and is typically an unwanted finding that requires removal for healing to proceed. Scar tissue forms later, during the remodeling phase, as the wound matures and collagen is reorganized, whereas epithelial tissue is involved in resurfacing the wound but does not
