1. The process of inflammation starts when the damaged area has turned red, warm, and painful due to acute inflammation. Blood vessels has dilated in order for blood that contains proteins such as antibodies, leukocytes, and blood clotting rush to the area as well increased capillary permeability. The next phase is the movement of phagocytes and neutrophils which are followed by monocytes to the interstitial fluid from the bloodstream which serves the purpose of engulfing damaged cells. After the inflammation process, the tissue is then ready to undergo repair and regeneration.
2. We are all born with an immune system known as innate or nonspecific immunity. It serves as a barrier between our bodies and dangerous chemicals while also serving to protect us from all other antigens. The immune response's initial line of defense is this. Cough reflexes and mucus that collects bacteria and other tiny particles may serve as examples. Other immune system components target antigens if they manage to evade innate immunity.
