Lymphatic/Immune System
Gabriela Torres Period 3
Lymphatic System
Compromised of a network of vessels that assist in the circulation of body fluids
Drains excess fluids from the tissue
Plays an essential role in the body defending and being resistant to diseases
Returns clean fluids and leaked proteins back to the blood
Humoral Response
Antibody molecules are secreted by plasma cells. Antigen that binds to the B-cell antigen receptor signals B-cells. Some B-cells become memory B-cells to respond to future encounters with the antigen.
Immune System
The bodily system that protects the body from foreign substances producing the immune response.
Functions as the body's defense against infections pathogens
Keeps pathogens out and attacks those that do enter the body
Cellular Response
The destruction of infected cells by cytotoxic T-cells. This response does not involve antibodies. Cell mediated immunity secretes cytokines. This response shows delay through permanent action against any pathogens.
Anatomy of the Lymphatic System
A one way system towards the heart that carries fluid with the help of the lymphatic vessels and has no pump
The lymph moves by milking action of skeletal muscles surrounding the lymphatic vessels
Innate and Adaptive Immune Defenses
Artificially acquired passive immunity
involves the injection of gamma globulin containing antibodies and is short-lived.
Naturally acquired passive immunity
occurs as antibodies are passed from mother to fetus and is short-lived.
Artificially acquired active immunity
occurs through the use of vaccines, without the person becoming ill from the disease.
Naturally acquired active immunity
occurs after exposure to the antigen itself.
Antigens
Consist of proteins, polysaccharides, glycoproteins or glycolipids that can trigger an immune resonse
Generally larger and more complex molecules
Antibodies
Soluble protein secreted by plasma cells that are derived from B-cells
Carried by body fluids, capable of binding specifically to antigens
Actions of Antibodies:
Complement fixation
(binding to antigen and "tagging" it
Opsonization
(labelsto be identified by other immune cells for phagocytes
Neutralization
(no longer active)
Aggulutination
(clump with other antibodies)
Precipitation
(becomes solid)
Cells in the Immune System
Lymphocytes (B-cells, T-cells), Neutrophils, and Monocytes/Macrophages
Disorders Associated with Immune System
AIDS
A stage where the body loses the ability to fight off common infections like diarrhea or a cold
HIV
A virus that destroys white blood cells and weakening the immune system
