Skin: The First Defense – Cells: The Second Defense
Our skin is the first line of defense from illness, 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, you see signs of washing your hands everywhere. By washing your hands with natural soaps, you destroy the antigen before it harms the body.
Immune cells are the second essential defensive components of our immune system. The three main categories of immune cells are phagocytes, T cells, and B cells. Each one of these cells are selective in the type of antigens they attack.
Below are the three types of cells and how they work to combat illness from our bodies.
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. .
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.
Have you ever heard the word antibodies?Antibodies combine chemically with substances which the body recognizes as alien, such as bacteria, viruses, and foreign substances in the blood. B cells are responsible for activating the antibodies, a protein that destroys antigens in the bloodstream. a blood protein produced in response to and counteracting a specific antigen.
