Which describes granulation tissue formation in the proliferation phase?

• A. Dense scar tissue with parallel collagen fibers
• B. Necrotic tissue formation
• C. Granulation tissue formed by new capillary loops
• D. Lymphatic drainage increase

Answer: (C)

In the proliferation phase of wound healing, tissue formation focuses on filling and vascularizing the wound bed. New capillary loops grow out from existing vessels (angiogenesis) and fibroblasts populate the area to lay down extracellular matrix, creating granulation tissue. This tissue is the pink, granular bed that fills the wound and provides the scaffold for later collagen deposition and epithelialization. The description of granulation tissue formed by new capillary loops best captures what happens during this phase. Dense scar tissue with parallel collagen fibers points to later remodeling, not the proliferation stage. Necrotic tissue formation describes dead tissue, not the newly formed vascularized tissue. Increased lymphatic drainage is not the defining feature of granulation tissue formation.
