PATHOLOGY

Detailed explanation-1: -The wound healing process is usually characterized as four sequential but overlapping phases: haemostasis (0–several hours after injury), inflammation (1–3 days), proliferation (4–21 days) and remodelling (21 days–1 year) [1].

Detailed explanation-2: -Proliferative phase – This phase begins about three days after injury and overlaps with the inflammatory phase. It involves cells called fibroblasts that help to produce new collagen, create new blood vessels, and repair the avascular epithelial tissue.

Detailed explanation-3: -Remodeling or also known as maturation phase is the fourth and final phase in wound healing and lasts from 21 days up to 2 years. In this final and longest phase, collagen synthesis is ongoing in order to strengthen the tissue.

Detailed explanation-4: -Fibroblastic Repair/Subacute Phase: Can begin at Day 4, up to 6 weeks. This phase begins as the inflammation settles down and your body begins to repair the damaged tissue by laying down collagen.
