Question

how does inflammation help the body fight off further infection?
inflammation keeps harmful substances away from healthy cells.
inflammation triggers the production of white blood cells.
inflammation drops the ph of blood.
inflammation raises the ph of blood.

Explanation:

Inflammation is a part of the immune response. When there is an injury or infection, blood vessels dilate, and immune cells (like white blood cells) are sent to the site. One of the ways inflammation helps is by keeping harmful substances (like pathogens from an infection) away from healthy cells. White blood cell production is more related to the immune system in general rather than specifically triggered by inflammation in the way described in option B. pH changes (options C and D) are not the main way inflammation helps fight infection.

Answer:

Inflammation keeps harmful substances away from healthy cells.
