Question 9 • Biology

How does inflammation help the body fight off further infection?

Answer
A
Inflammation keeps harmful substances away from healthy cells.
B
Inflammation triggers the production of white blood cells.
C
Inflammation drops the pH of blood.
D
Inflammation raises the pH of blood.

Explanation

Inflammation helps contain an infection by increasing blood flow and making nearby blood vessels more permeable, allowing immune defenses to reach the affected area and helping limit the spread of harmful substances to healthy tissue. It does not primarily trigger the production of white blood cells, and it does not raise or lower the pH of the blood.
