Question

Becoming exposed to or infected with an infectious microbe does not necessarily mean developing noticeable disease. Explain.

Answer 1

Hint:-Becoming exposed to or infected with an infectious microbe does not necessarily mean developing noticeable disease, this is because our immune system is so maintained that it has ability to detect and kill any pathogens/ antigens or any foreign material that enters our body.

Complete step-by-step solution:-
Human beings have two types of immunity in them whose basic work is similar, but it varies in some particular diseases. Those are “Innate immunity” and the second one is “Adaptive immunity”. Innate immunity’s main job is to detect and fight and then kill antigens, harmful substances that enter our body from outside like skin or digestive systems. This is the reason that becoming exposed to or infected with an infectious microbe does not necessarily mean that we will develop a disease because we have that immunity that fights within us and protects us from getting infected that is why most of the time we did not require any medicine for the recovery. Adaptive immunity is the type of immunity in which certain antibodies are made in response to specific antigen when we come in contact with that microbe or infectious agent, these antibodies remain in our body for lifetime and can fight if we again come in contact with the same antigen. This is also known as ‘Acquired immune’ or ‘specific immune’.

Note:- The tasks of our immune systems are that are present in our body to fight disease causing germs, to identify and neutralize harmful substances from the environment and lastly to fight disease causing changes in our body it may include even cancer cells. Our bodies have their own cells which are capable of fighting foreign substances entering our body.
