The role of our immune system is to protect us from any foreign substance that could harm the body. These foreign substances are also known as antigens. Antigens include bacteria, viruses, parasites, and fungi. When those organisms are found in the body, they trigger the immune system, which, in return, try to destroy the antigen with various mechanisms. Our immune system can be divided into two categories; innate and adaptive.

Innate Immune System

The goal of the antigen is to get into the body. Our innate immune system is the first responder of our body, which includes our skin, immune system cells, and some chemicals in our blood.


Our skin is the first line of defense, which serves as a surface barrier to stop the virus or bacteria from getting into our body. That also explains why, when we are in flu season and now covid, you see signs of washing your hands everywhere. By washing your hands, you destroy the antigen before it harms the body.  

Immune Cells

Immune cells are also essential components of our immune system. Some cells are more selective than others in the type of antigens they attack. The three main categories of immune cells are phagocytes, T cells, and B cells.


The large white cells called phagocytes are antigen eaters. They can be found in our blood and tissues. These cells are often the reason why we will notice inflammation in the body. Inflammation increases blood flow, which serves a fundamental purpose when it comes to sending immune cells in a specific area of the body. In a latter blog you will learn about the food that you can eat to reduce body inflammation.

T Cells

T cells are there to regulate the immune cells. It can eliminate them or activate them. You might have heard of the term killer cells. That term is used to describe a type of T cell whose purpose is to kill any cells that are infected with the antigens or cells that seem abnormal.

B Cells

Have you ever heard the word antibodies? B cells are responsible for activating the antibodies, a protein that destroys antigens in the bloodstream.

Now let’s explore the second category of our immune system, the adaptive immune system.

Adaptive Immune System

We should be very grateful for our adaptive immune system since it is the system that remembers past attacks from antigens and is triggered to combat the same antigen more effectively.

Have you ever received a vaccine? The chances are that you probably have. Vaccines will trigger your immune system to create an adaptive immune system so that when you reencounter the antigen, it’s easier to fight it.

The adaptive immune system remembers the antigen and can send immune cells that will specifically attack that type of antigen. This process is why it is much quicker at resolving the issue and gives less time for the antigens to multiply in the body.

Another vital system in your body that prevents you from getting sick is the lymphatic system.

Lymphatic System

The lymphatic system is composed of tissues, vessels, and nodes that allows the body to get rid of toxins, and any waste that can be harmful to the body. It’s role is primarily to circulate a liquid called lymph, which contains white blood cells (like T cells and B cells) in the body. In a later post I will go over some tips and ideas on how to improve our lymphatic system.

Colostrum has over 100 times more immunoglobulins than regular milk. Colostrum is also rich in transfer factors that educate and modulate the immune system, causing it to recognize specific antigens. These transfer factors also help the immune system to recognize the difference between normal tissue and pathological microbes. These transfer factors include immunoglobin G (IgG).

The transfer factors from colostrum are able to boost natural killer cell (NK) activity and calm a hyperactive immune system through activating suppressor T cells. This improves the intelligence of the immune system and allows it to function with greater efficiency. These transfer factors also act as a catalytic memory agent for the immune system to alert naive immune cells of an impending danger.

Colostrum-based IgG molecules can be a lifesaver to someone who is suffering from acquired immune deficiency syndrome (AIDS). These individuals are not able to effectively produce sufficient IgG on their own to combat pathogenic microbes like Cryptosporidium parvum. According to the Health Science Institute’s Underground Cures, “colostrum is able to ameliorate or completely eliminate the clinical symptoms of those suffering from cryptosporidiosis.”

A healthy immune system is so important that some scientists say that a healthy immune system could prevent virtually every known disease.
