Question

Quizplus · Accepted Answer

Inflammation is the nonspecific defense mechanism that comes to the rescue in case of deep puncture wounds. It causes redness, swelling, and warmth around the wound, which helps in the movement of immune cells to the site of injury to initiate the healing process. Natural killer cells are responsible for killing cancerous or infected cells, acidic skin secretions help in preventing bacterial growth on the skin, and epithelial cells with cilia protect the respiratory system from pathogens by pushing them out of the airways.
