- - Neutrophils: The most abundant white blood cells, accounting for 55-70%. They have a segmented nucleus and are often call polymorphonuclear leukocytes. Are largely responsible for protecting the body against infection and are key components of the first response to foreign body invasion. They are readily attracted by foreign antigens, which they destroy by engulfing and digesting the antigens.
- - Monocytes: Mature in the blood during their first 24 hours and then travel to the tissues, wher they differntiate into macrophages, which function primarily as scavengers for the tissues. Monocytes and macrophages represent one of the first lines of defense in the inflammatory process.
- - Lymphocytes: mediate the acquired immune response. Although most are found in th lymphoid tissues, many are found in circulaing lymph and blood as well. Two basic types B lymphocytes and T lymphocytes.

- a nonspecific cellular and humoral response that operates as the first line of defense against pathogens. Most notive immunity is associated with the initial inflammatory resonse.
What is Acquire immunity?
- a highly specific, inducible, discriminatory, and unforgetting method by which armies of cells respond to an immune stimulant. Arises when the body is exposed to a foreing substance or disease and produces antibodies to that invader.
How do antibodies work?
- - A macrophage engulfs the antigen via phogocytosis and digests the antigen, pushing the discarded particles to the cell surgace. The remnants interact with Bcell and a helper T cell.
- - The antigen binds to both the b cell and the helper T cell, activatin both.
- - The activated helper T cell secretes a lymphokine, a substance that stimulates the B Cells to produce a clone. The clone is a group of identical cells formed from the same parent cell. Clone comprises two types of identical cells that have different functions: plasma cells, which make the antibodies, and memory cells, which remember the initial encounter with the antigen.
What are the three ways antibodies make antigens more visible to the immune system?
- - Antibodies act as opsonins, in where the antibody coats an antigen to facilitate its recognition by immune cells. Antibodies are not toxic by themselve, but they labe antigens so that other immune cells will attack them.
- - Antibidies cause antigens to clump for easier phagocytosis.
- - Antibodies bind to and inactivate some toxins produced by bacteria. Macrophages can then ingest and destroy the inactivated toxins.
What are the two major ways T cells lymphocytes recognize antigens and contribute to the immune system?
- - Secreting cytokines that attract other cells.
- - Becoming cytotoxic and killing infected or abnormal cells.
What are the four subgroups of T cells?
- - Killer T cells: Destroy the antigen.
- - Helper T cells: activate many immune cells including B cells and other T cells.
- - Suppressor T cells: Suppress the activity of other lymphocytes so they do not destroy normal tissue.
