This is how children strengthen their immune systems

What is the immune system?

The immune system is a defense against the body. All of its cells are made in the bone marrow, which are white blood cells or leukocytes. There are phagocytes, T cells and B cells. Since every cell in the body contains certain proteins, the leukocytes attack all cells and substances that do not carry these proteins. Phagocytes move between the cells in the tissue and unspecifically turn against all foreign substances (antigens) such as invaded pathogens, foreign bodies and dead body cells.
