Immune System |
Helper T and B Cell The Helper T and B cells are very important for the immune response. When a Helper T cell is told what infection it is by the dendrite cell, it multiplies into three different groups. Some to go and fight, some to make memory T Cells and others to activate B Cells. Once B Cells are activated, they make antibodies that attack pathogens and make memory B Cells. The antibodies created allow for the Killer T Cells and Macrophages to easily destroy pathogens.

The immune system helps keep you healthy and alive. It does this by fighting off pathogens. Pathogens are foreign invaders that attack cells and cause disease. Your immune system fights the pathogen with the following organs/structures: Lymph Nodes, Bone Marrow, and Stem Cells. Lymph Nodes remove pathogens form lymph fluid. Bone marrow produces lymphocytes such as T-Cells and B-Cells. A Stem Cell can be any tissue or blood cell that helps fight. There are two ways your body responds to a pathogen. They are called Innate and Adaptive. Innate is a immediate response within seconds. This response kills all pathogens and has no memory of it. Adaptive is a gradual response generated over 3-4 days. It targets specific pathogens and memorizes them. This allows you to be able to fight them off easily in the future. The immune system works along with the lymphatic system to help cleanse your cells and blood from the pathogen. It also works with your integumentry system which is your first line of defense. Overall, the immune system helps you maintain homeostasis by keeping cells and your body healthy.
The Immune Response The video below goes into more depth in explaining how the immune system responses to a pathogen.
