Chapter 15, Problem 1TMW
Summary Introduction
To determine:
The reason why the body’s skin and mucous membrane barriers are not significant factors in body’s resistance to infection by hyperthermophiles.
Introduction:
Skin is a barrier to microorganisms. However, some microbes invade the skin through natural openings of the skin, sweat glands and hair follicles. They may also enter through wound, damage or cut on the skin. There are some
The mucous membranes are soft and living cells. They are present in organ systems such as gastrointestinal, respiratory, urinary, and reproductive and conjunctiva. As these membranes are soft cells, microorganisms can easily enter into the body through them. The respiratory tract is the most susceptible route for microbes.

Students have asked these similar questions
Which is an example of chemotaxis?
the movement of cells toward or away from a chemical stimulus
the squeezing of cells between the cells lining capillaries in order to attack invading microbes
the transport of substances across the cytoplasmic membrane
the attachment of phagocytes to a microorganism by binding to complimentary proteins
Increase in body temperature should increase the rate of metabolism of microbes instead of killing them. How does a fever help our bodies fight infection?
Explain the following
Sweat glands in the armpits secrete perspiration with a pH close to neutral (7.0). How does this fact help explain body odor in this area as compared to other parts of the skin?
Human immunodeficiency virus (HIV) preferentially destroys CD4+ cells. Specifically, what effect does this have on antibody and cell-mediated immunity?
How does a phagocyte “know” it is in contact with a pathogen instead of another body cell?

- Which of the following is an example of a chemical barrier to infection? Cellular junctions Mucosal membranes Defensins O Skinarrow_forwardWhat feature of the skin creates a physical barrier to microbial invasion? Group of answer choices The outer layers are composed of cells full of protein which forms NETs to trap microbes until they are shed. The surface is constantly patrolled by phagocytic cells. The outer layers are dead cells, tightly linked together, and are frequently shed. All of these mechanisms can provide defense against microbial invaders. The oil secreted onto the surface of the skin traps microbes, preventing penetration. The fine hairs move microbes to mucous membranes for phagocytosis.arrow_forwardIncrease in body temperature should increase the rate of metabolism of microbes instead of killing them.
