Inflammation keeps harmful substances away from healthy cells.

Explanation:

Inflammation is the immune response against tissue damage wherein the damaged cells and the mast cells release histamine. Histamine dilates the blood capillaries and allows the buildup of tissue up at the site of damage.

The phagocytic immune cells such as neutrophils and monocytes arrive at the site of injury and kill the pathogen by phagocytosis. Hence, inflammation does not allow harmful toxins or chemical to reach the healthy cells.

The answer is inflammation keeps harmful substances away from healthy cells.

Explanation:

Any injury, such as invasion of microorganisms, causes inflammation in the affected area. Inflammation is a complex process, where damaged tissues release substances that cause inflammation to protect healthy cells and that stimulate the immune system to lift a barrier around the area, attack and destroy any invader, eliminate dead and damaged tissue and start the repair process .

During inflammation, the blood supply increases, which helps immune cells reach the affected area. The area near the infected body surface becomes red and hot.
