What is immune response?

What Does immune response Mean

A response is a response that one subject provides to another when requested or called. The concept can also be used with reference to the satisfaction of a consultation or the reaction to a stimulus.

Immune , on the other hand, is an adjective that comes from the Latin word immūnis and refers to that which cannot be violated, that does not suffer the consequences of a disease or that is related to immunity (resistance to a pathogen).
It is known as an immune response or immune response to the way the body recognizes and defends itself against those agents that are strange and harmful to it . This response is regulated by the so-called immune system.

This system is made up of various structures that allow, through different processes, to identify and eliminate pathogens that could cause harm . For the immune response to be correct, it is imperative that the immune system accurately recognize harmful agents and differentiate them from healthy cells.
The immune response is usually a reaction to molecules found on the surface of bacteria , viruses , cells, or fungi . The immune response can also be linked to the presence of a foreign particle or a toxin.
There are many types of immune responses that our body performs in the presence of "foreign" elements. Specifically, the most common are mucus, which is responsible for trapping small particles and bacteria, as well as tears and even gastric acid or the "oil" that the skin has.
A simple example of an immune response is coughing , a reflex that arises when a foreign agent appears in the airways. In this case, it is an innate immune response, which all people have from birth.
As we have mentioned, the existence of an adequate and efficient immune response is directly protecting the body against various disorders and diseases. However, it can also be the case that this response is inappropriate, excessive or even deficient, which will lead to serious consequences for the immune system.
Specifically, what will happen is that the body has to face adverse consequences, such as the following:

-What is called anaphylaxis and which is an allergic-type reaction that, in some cases, can even lead to cause death. Its most frequent symptoms are vomiting, shortness of breath, diarrhea, abdominal pain, loss of consciousness, wheezing, redness of the skin, a noticeable swelling of the face ...

-Allergy, also known as hypersensitivity. This can be caused by both food and plants, insect bites, medications, dust or pollen, textile materials ...

-In the cases of people who have undergone an organ transplant, the deficient immune response may be the rejection of it.

-Reaction called serum sickness, which occurs when a person receives a medicine that contains proteins. What you experience is a rejection of it that translates into hives, fever or joint pain.
