What is the term for the process by which the body automatically reacts to tissue injured by trauma or bacteria?
Vasodilation
Inflammatory response
Innate immunity
Adaptive or acquired immunity
The Correct Answer is B
A. Vasodilation is a component of the inflammatory response, but it is not the term that encompasses the entire process.
B. Inflammatory response is the body's automatic reaction to tissue injury, involving a series of events such as vasodilation, increased permeability, and the recruitment of immune cells to the site of injury.
C. Innate immunity is the first line of defense against pathogens, but the inflammatory response is more specific to the reaction to injury or infection.
D. Adaptive or acquired immunity is a more specific immune response that develops after exposure to a specific antigen, not the immediate response to injury.
