Question

Quizplus · Accepted Answer

Inflammation is characterized by redness, heat, swelling, and pain.

Answer: D 
 Inflammation can also be initiated by non-pathogenic stimuli such as tissue injury or exposure to irritants, in addition to pathogens. Therefore, option D is incorrect.

Answer: A and C 
 Inflammation is not classified as a specific immune response, but rather as a non-specific immune response. Specific immune response involves the activation of B and T cells, which are responsible for recognizing and responding to specific antigens. Inflammation is not cell-mediated immunity, which is a specific immune response that involves cytotoxic T cells killing infected cells.
