Detailed explanation-1: -The innate immune system is the body’s first line of defense against germs entering the body. It responds in the same way to all germs and foreign substances, which is why it is sometimes referred to as the “nonspecific” immune system.

Detailed explanation-2: -Overview. Your body’s first line of defense includes the skin and other barriers that keep pathogens out of your body. The first line also includes tears, mucus, cilia, stomach acid, urine flow, and friendly bacteria.

Detailed explanation-3: -Skin, tears and mucus are part of the first line of defence in fighting infection. They help to protect us against invading pathogens. You have beneficial bacteria growing on your skin, in your bowel and other places in the body (such as the mouth and the gut) that stop other harmful bacteria from taking over.

Detailed explanation-4: -“White blood cells are among other places located in the oral mucosa, and they represent the body’s first line of defence against infectious agents. The mucus in the mouth causes the white blood cells to throw out a ‘net’ that traps bacteria”, explains Ole Sørensen from the Division of Infection Medicine.

Detailed explanation-5: -Skin, tears and mucus form the first line of defence of the body against microbial invasion. These are called so because they are the first barriers which the pathogens encounter when they enter a body during an infection.
