The human body’s immune system

Elderly people were advised to take special precautions due to the outbreak of the Code 19 epidemic around the world, as their immunity weakens with age and any virus can quickly attack their body. There is no doubt that with good nutrition you can boost your immune system. Human resistance is an intricate network of cells and molecules outside the human brain. Which protects us from many dangerous viruses and germs. Its ingredients also warn of danger, disturb it by increasing it, calm it down and change it. 

This is the system that confuses professors of biology, even if they are not immunologists themselves. The fact is that the word immunity itself confuses people. Resistance) means that the system produces antibodies (antidotes) to the body after a (toxic) attack by a germ or combines the body’s immune cells. When they use this term, it means that they hope that they are safe from infection.

The body’s strong immune system also protects against infectious diseases such as cancer. In this system, many cells work together to fight epidemics and diseases. The Kahir cell performs a very useful function of destroying all kinds of harmful cells that enter the body after identifying and marking them.

B cells make useful antibodies against harmful invading cells. Each of these B cells makes a special type of antibody. For example, a B cell produces antibodies against the common cold and flu, while cells that fight cancer produce antibodies against it that collect cancer cells in one place and disrupt their normalcy. Starts the process of immunity against them by putting CD4 helper cell. These cells signal other cells for help (e.g. CD8 killer T cells) and ensure that they destroy the damaged cells as quickly as possible. These cells make contact with B cells before making antibodies.

CD8 killer T cell. They destroy thousands of harmful cells that are exposed to viruses every day. They target and destroy cancer cells. Dendritic cells. They digest exogenous and cancerous cells and display their proteins on their surface, where other immune cells, after better identification, destroy the damaged cells. Macrophages are large cells in the immune system. They eat germs and harmful cells. 

Like dendritic cells, they also provide the body’s immune cells with antigens for the identification and destruction of damaged cells. Regulatory T cells work to check and balance and ensure that all cells meet their needs. Don’t be too active. An unhealthy immune system is actually an overly active immune system. This is called autoimmune disease.

Molecules of the immune system

Antibodies are actually proteins that stick to harmful foreign invaders and are called antibodies that are cells of germs, viruses and tumors. These mark on harmful cells, in order to destroy them. The function is performed by other cells in the immune system. Our cell. Adequate, timely and coordinated immune response to infection and tumor cells.

Tissues and organs of the immune system

The appendix is ​​a thin tube that runs down the right side of the abdomen. Its exact function in the immune system is still unknown, as people survive without it. One hypothesis is that the immune system stores germs that aid digestion. Bone marrow It is a soft sponge-like substance found inside the bones. The most important part of the immune system is the immature cells that either divide and form stem cells (which are cells that can be transformed into any type of cell as needed) or mature. They become red blood cells. 

They carry oxygen and carbon dioxide into the bloodstream or are converted into white blood cells, which include B and T cells. Or they form platelets that make blood clots and stop them from flowing. Lymph nodes These tiny glands that are all over the body filter out viruses, germs and cancer cells. Later they are destroyed by specific white blood cells. Lymph nodes are in this place. Where T cells learn how to destroy harmful invading cells inside the body.

The human skin is the largest organ in the body, which is the body’s protective shield and protects the body from pathogens and toxins, which also have their own immune cells and lymph nodes. The spleen is one such organ. What is on the left side of the flour is blood filtered and white blood cells and platelets are stored. In this, the number of the most important immune cells (B cells) increases according to the strokes, so that the invaders from any crack in the body can fight against the external cells.

The thymus gland is located in the upper part of the chest below the left chest bone. It is also the site of maturation of vital immune cells (T cells) that can fight infection and cancer cells. The body’s strong immune system can protect us from cancer and eliminate tumors that form in the body. Immune therapy is a type of treatment that awakens the strength of the immune system. Through its action, immune therapy enables the body’s immune system to target all types of cancer and restore human health. And save many lives.
