Question

What is inflamatory reaction and allergic reaction.

Answer 1

Inflammatory response occurs when the tissues come across with some bacteria, trauma, toxins or heat. The damaged cells release several chemicals like histamines and prostaglandins. These chemicals cause blood vessels to leak fliud in their surroundings thus isolating the foreign substance resulting in a swelling.

An allergic reaction happens in people with an oversensitive immune system towards a particular substance or al allergen which is usually not harmful for the majority. It produces some allergic symptoms when the body is exposed to these allergens.
