PATHOLOGY

Detailed explanation-1: -Mucus serves as a barrier preventing pathogens from getting to the tissues of the body.

Detailed explanation-2: -Skin, tears and mucus are part of the first line of defence in fighting infection. They help to protect us against invading pathogens.

Detailed explanation-3: -Your primary defense against pathogenic germs are physical barriers like your skin. You also produce pathogen-destroying chemicals, like lysozyme, found on parts of your body without skin, including your tears and mucus membranes.

Detailed explanation-4: -Keep your germs to yourself: Always wash your hands after sneezing, blowing your nose, or coughing, or after touching used tissues or handkerchiefs. Use warm water and soap to wash your hands. If you don’t have soap and water, use alcohol-base hand gel or disposable wipes.

Detailed explanation-5: -Keep it clean: Wash hands and surfaces often. Harmful bacteria can spread throughout the kitchen and get onto cutting boards, utensils, and counter tops. To prevent this: Wash hands with soap and hot water before and after handling food, and after using the bathroom, changing diapers; or handling pets.
