The Immune System Essay
• Bone Marrow Produces all the cells of the immune system through a process called hematopoiesis.
• Thymus Produces mature T cells through a process called thymic education.
• Spleen Its primary role is to filter the blood of antigens. This is done by the macrophages and dendritic cells that capture the antigens.
• Lymph Nodes Its primary role is to filter the bodily fluids of antigens, similar to the spleen, this is also done by the macrophages and dendritic cells capturing antigens.
• T- Cells There are two main types of the T-cell: T helper subset CD4 + T, which enhances immune responses by activating white blood cells to fight off infection and the T killer/ suppressor subset CD8 + T, which directly kills infection (viral and parasitic).
• Natural Killer Cells (NK cells) A more effective killer cell that is similar to the T-cell. Mainly functions as effector cells that are capable of directly killing certain infections (herpes and cytomegalovirus).
• B Cells Produces antibodies. When antibodies are produced a signal travels around the body informing other cells and organs to start removing the foreign substance from the body.
• Granulocytes/ Polymorphonuclear (PMN)…
