How does the skin and mucous membranes help prevent infection by a pathogen?

Answer 1

The physical and chemical factors that provide protection from disease in the skin and mucous membranes are the many layers of closely packed, keratinized cells, in the epidermis that provides a formidable physical barrier to the entrance of microbes. The epithelial layer of mucous membranes secret a fluid called mucus that is sticky and traps microbes and foreign substances. The lacrimal apparatus produces and drains away tears in response to irritants, diluting microbes and keep them from setting on the surface of the eyes. Sebaceous glands of the skin secrete an oil substance called sebum that forms a protective film over the surface of the skin. Perspiration helps flush microbes from the surface of the skin and contains lysozyme, an enzyme capable of breaking down the cell walls of certain bacteria.

Answer 2

The appropriate use of gloves, face shields, masks, protective eyewear, aprons, and gowns as needed. In the emergency room you also need to make use of mouthpieces, ventilation bags, and other ventilating deives in order to avoid direct contact with saliva or possible blood due to an injury.

Answer 3

1. the dry layers making up the epidermis are not easily colonized. 2. sebum, secreted by oil glands, inhibits growth 3. salts in perspiration create a hypertonic environment

Answer 4

Interferons, complement system, transferrins, antimicrobial peptides, natural killer cells, phagocytes, inflammation and fever.

Answer 5

They form strong barriers that prevent pathogens from entering the body. -Yami(:
