How is it that we are not in a state of continuous infection from the microbes we encounter every day? **Question:**How is it that we are not in a state of continuous infection from the microbes we encounter every day?**Multiple Choice Options:**- The immune system provides an overlapping network of host defenses. - Access to lifesaving antibiotics prevent most people from developing infections. - The immune system modifies genes of bacteria to prevent them from causing an infection. - Most of the microbes we encounter are harmless and will not cause disease.

Immunology is the branch of science which deals with the study of the immune system, immune response to foreign substances, and their role in fighting infection. Any foreign substance invading the body and capable of stimulating an immune response is called an antigen. The protective chemicals produced by the immune cells of the body in response to antigens are called antibodies. The term immunity refers to the ability of a body to recognize, neutralize, and eliminate foreign substances or resist a particular infection. Immunity is basically classified into two types: Innate immunity and adaptive immunity.We are not in a state of continuous infection from the microbes we encounter every day because the immune system provides an overlapping network of host defense, there is access to life-saving antibiotics that prevent most people from developing infections and most of the microbes that we encounter are harmless and not cause disease, The immune system provides an overlapping network of host defense- The immune system is a complex system including various molecular and cellular components that provide a defense against various infectious diseases caused by the microbes. So, the immune system provides an overlapping network of host defense Access to lifesaving antibiotics prevent most people from developing infections - Antibiotics are the drugs that are used as medicines against infectious diseases. Antibiotics kill the microbes mostly bacteria present in the body or they stop the spread of the infection. Hence, access to lifesaving antibiotics prevents most people from developing infections. The immune system modifies the gene of the bacteria to prevent them from causing an infection- The immune system is a complex system including various molecular and cellular components that provide a defense against various infectious diseases caused by the microbes. The immunity achieves it by using various barriers and producing antibodies that fight against the foreign body called an antigen. The immune system does not modify the gene of the bacteria to prevent them from causing an infection. Most of the microbes that we encounter are harmless and not cause disease- There are innumerable microbes present around us. A pathogen is a virus or bacteria that is capable of causing disease. Not all microbes are pathogenic in nature. Most of the microbes are not pathogenic. Hence, most of the microbes that we encounter are harmless and not cause disease.
