Wound healing occurs in four stages: Haemostasis – The body forms a clot to stop bleeding. Inflammation – White blood cells fight infection and clear away debris. Proliferation – New blood vessels, collagen, and tissue are formed. Remodelling – The tissue gradually strengthens as the wound matures. Any disruption in these phases—such as poor circulation, infection, immobility, or chronic illness—can delay healing.

Lung function refers to the ability of your lungs to absorb oxygen and expel carbon dioxide efficiently. It is measured using several parameters, including tidal volume, respiratory rate, and forced expiratory volume (FEV1). When lung function is reduced, it can cause shortness of breath, fatigue, and decreased endurance, making everyday activities challenging.
