What You Must Know about Immune Response

14 November 2019 | 1 comments | Posted by Walter Moore in Doctors Orders

How the immune system works

What is the immune response? It is the reaction through which the human body identifies and protects viruses, bacteria, and other elements that seem damaging and alien. The human immune system protects you from disease-causing viruses by responding to antigens.

Antigens are nothing but proteins on the cell surface, bacteria or fungi. Then, did you know that chemicals, toxins, foreign particles, and drugs could also be antigens? The immune system identifies and obliterates or destroys materials containing antigens.

According to an article published on Huffington Post Canada, you can also boost immunity with foods like chicken noodle soup, mushrooms, onion, garlic, citrus fruits, and more. Read on to learn more about the immune response.

Innate immunity

Nonspecific or innate immunity is that defence system with which we all are born. It helps in protecting you against antigens and involves obstacles to keep damaging elements from intruding your body. The hurdles are called the first line of defence when it comes to immune response. The typical examples are enzymes in the skin and tear oils, cough reaction, skin, and mucus trapping bacteria, and little particles, and stomach acid.

Did you know that innate immunity also comes in the form of protein, known as innate humoral immunity? Even when an antigen gets past these obstacles, the other parts of the human immune system attack and hurt the antigens. You know now that antigens are substances triggering an immunogenic response.

Passive immunity

Passive immunity occurs because of antibodies, which are manufactured in the body, save for your own. When it comes to passive immunity, they have passive immunity, as they are born with the said antibodies.

Then, these antibodies are moved via the placenta from the mother to the baby. The said antibodies wane when the baby is 6 to 12 months of age. Passive immunization also occurs due to an injection of antiserum that holds antibodies, which are produced by a different individual or living being.

It offers instant defence against an antigen but does not provide continuous protection. Tetanus antitoxin and immune serum globulin for hepatitis susceptibility are typical examples of passive vaccination.

Blood components

When it comes to this immune system, it incorporates specific kinds of white blood cells. It also means proteins and chemicals in the blood. These include complement proteins, antibodies, and interferon. A couple of these substances attack foreign elements in the human body.

The others team up to assist the cells in the immune system. As far as lymphocytes are concerned, these are a kind of white blood cell, which are B and T type lymphocytes. When it comes to B-lymphocytes, these become cells creating antibodies.

Antibodies fasten to a precise antigen and make it simpler for the immune cells to damage the antigen.T lymphocytes hit antigens unswervingly and assist in controlling the immune response. They to discharge chemicals, called cytokines that manage the whole immune response.

These B and T lymphocytesletthe immune system to act in response quickly and more resourcefully the next time a person is vulnerable to a similar antigen. In most of these situations, it will stop you from falling sick.


A sound and healthy immune system protect us from ailments and disorders. Therefore, excess or too little or inaccurate immune response leads to immune system issues or complications.
