Summary Introduction

Introduction:

Immune system of the human body is divided into two main branches namely the innate immunity and the adaptive immunity. Innate or the body’s first defense mechanism is present since birth and this defense mechanism is non-specific, which means it acts as a barrier in for every foreign body irrespective of its structure. Adaptive immunity of the body comes in later stages, when the body is introduced to pathogens. It is a specific type of defense mechanism.
