The image illustrates the role of oxygen in promoting the healing process of an injured body part. On the left side, a conceptual hyperbaric oxygen chamber is depicted surrounding a skin wound, highlighting that an oxygen-rich environment accelerates natural healing. On the right, a detailed cross-section of the wound site shows red blood cells carrying oxygen, with arrows indicating increased oxygen dissolved in plasma. The illustration highlights cellular mechanisms of oxygen-induced healing: activation of fibroblasts stimulating collagen synthesis, promotion of angiogenesis which forms new blood vessels, and enhanced immune cell function enabling better bacteria killing. The colors and labels clarify the physiological processes that oxygen supports in tissue repair.
