TestHub · Accepted Answer

There are two types of immunity: innate and acquired immunity. Innate immunity is present since birth, including many barriers like physical, physiological, cellular and chemical etc. Barriers are essential as they prevent microbes from entering our bodies. These form the essential first line of defense. Physiological barriers include those acids in the stomach, tears from eyes, saliva in the mouth etc. Skin is a physical barrier, while interferons are cellular barriers.
