Question
Chapter 27, Problem 1SA
Summary Introduction
To analyze: Three non-specific ways in which the immune system combats the pathogens.
Introduction: Immune system is a type of biological network that protects organisms from disease. It allows the detection and prevention of disease-causing agents such as bacteria and viruses.
Expert Solution & Answer
Explanation of Solution
Three non-specific ways in which the immune system combats pathogens:
- Physical barriers: this is the first level of defense, by preventing the pathogen from entering and establishing the body. The skin, hair in the nose and ears, and mucus membranes are examples of physical barriers. They are some chemicals that stop the growth of the pathogen.
- Non-specific immunity: it is an immune cell that attacks all foreign objects, without specifically attacking one type of pathogen.
- Specific immunity: refers to the cells and molecules that recognize the specific pathogens, remember them and attack them strongly when they re-enter the body. This is slow to activate, but the best protection once activated. It is also called adaptive immunity.
