PATHOLOGY

Detailed explanation-1: -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-2: -“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-3: -First line of defence The surfaces of the body – the skin, digestive system, and the lining of the nose – are covered by a community of microbes called the normal body flora. They help protect the host from becoming infected with more harmful micro-organisms by acting as a physical barrier.

Detailed explanation-4: -The macrophages and neutrophils of the innate immune system provide a first line of defense against many common microorganisms and are essential for the control of common bacterial infections.
