Bаrrier breаch, inflаmmatiоn, and phagоcytоsisA person gets a small cut on the forearm while gardening. The cut breaks the normally continuous skin surface, and bacteria from soil reach the underlying tissue. The area becomes locally warm and swollen, and phagocytes begin engulfing bacteria and damaged-cell debris.In 3–4 sentences, explain how the barrier breach, inflammation, and phagocytosis are connected in this scenario. Then state one broad difference between this innate response and an adaptive immune response.
