The Immune System
Major Functions of the Immune System
It recognizes bacteria and other harmful substances that enters the body.
Doesnt let disease spread as quickly or at all
The immune system provides protection to itself from disease
Its a complex of cells that keep a record of every germ
It has the innate immunity and the adaptive immunity to protect with it
Major functions of the Lymphatic system
Gets rid of toxins and waste.
It moves fluids through certain vessels called lymphatic vessels.
Produce and release lymphocytes, monocytes, and antibodies
Maintains body fluid levels
Different types of cells
B cells: they are in the humoral immune system and are specifically for mediating the production of antigens.
Dendritic cells: Its main function is to process antigenic material and present it to the T cells
Cytotoxic T cells: kills many different kinds of cells such as cancer cells, or cells that are infectious or damaged.
Phagocytes: There job is to protect the body by ingesting harmful foreign particles, bacteria, or dead cells.
Helper T cells: they help the Cytotoxic T cells to destroy the targeted cells. It activates B cells to secrete antibodies and macrophages to destroy ingested antigens.
NK cells: Its a specialized cell that controls different types of tumors and infections by slowing down spread.
It has the first and second line of defense. First line is the skin and the mucous.
Second line of defense consists of proteins, phagocytes, natural killer cells, inflammation, and fever.
Its a system that is made up of barriers that aim to keep viruses, bacteria, parasites, and other particles out your body.
Adaptive Immune system
Adaptive immunity makes up the third line of defense which it attacks certain substances
The adaptive immune system has the advantage of flexibility and immunologic memory
Adaptive immunity is an immunity that happens after exposure to a antigen such as from a vaccination.
Diseases or disorders related to the Immune system
Hodgkin's disease is acquired through immunodeficiency that causes cancer of B cells which kills lymph node cells and leads to immunodeficiency.
Severe combined immunodeficiency syndrome and its caused by a rare mutation in different genes that mess up the development and function of infection fighting immune cells.
Immunodefiency is a condition that is acquired and it disables the function or production of immune cells or molecules.
Autoimmune disease: results when immune system loses ability to distinguish itself from foreign invaders.
Human immunodeficiency virus that cripples the immune system by messing with the activity of the helper T cells.
Lymphatic system divisions
Primary Lymphoid Organs
Thymus makes hormones to help T cells develop and keep the immune system working properly
Red bone marrow helps produce blood cells and it contains hematologic stem cells which are used to form blood cells
Secondary lymphoid organs
Spleen fights invading germs in the blood and it controls the blood cells. Filters blood and removes old or damaged blood cells
Lymph Nodes are glands that monitor and clean the lymph as it filters. It filters damaged cells and cancer cells.
Tonsils stop most germs from coming through the body from the mouth or nose
Peyers patches monitors intestinal bacteria populations and prevents the growth of bacteria in the intestines.
Appendix function is unknown but there is a theory that states it acts as a storehouse for good bacteria or it is completly useless.
