Final answer:
In the proliferative phase of wound healing, the formation of granulation tissue occurs, involving fibroblast activity and angiogenesis to replace lost collagen and create vascularized tissue. The event that occurs in the proliferative phase of wound healing is C. Formation of granulation tissue.
Step-by-step explanation:
The event that occurs in the proliferative phase of wound healing is C. Formation of granulation tissue. During this phase, fibroblasts from the surrounding connective tissues replace the collagen and extracellular material lost by the injury.
Angiogenesis occurs, resulting in the vascularization of the new tissue known as granulation tissue. This granulation tissue is important because it is rich in collagen and blood vessels, creating the necessary structure and blood supply for the tissue to continue to heal and regenerate.
