Lymphatic/ Immune System - Coggle Diagram
Lymphatic/ Immune System
Major functions of the Lymphatic & Immune systems
immune system
functions as body's defense against pathogens
keeps pathogens put and attack them
lymphatic system
network of vessels assisting in circulation of body fluids
collect and carry away excess fluid
return clean fluids and proteins back to the blood
drain excess fluid from tissue
Anatomy of the lymphatic system
tonsils
cervical lymph nodes
red bone marrow
spleen
thymus
lymphatic vessles
acquired immunity
naturally aquired
active
infection contact w/ pathogen
passive
antibodies passed from mother to infact
artificially aquired
active
vaccine
passive
infection of immune system
Humoral response and cellular response
humoral
helper T- cell release cytokines that activate B cells
plasma cells produce & secrete antibodies
B cell become activiated
T- cells some B cells become memory B cells
cell
activated T cells interact w/ antigen
T cell becomes activated
T cells synthesize & secrete cytokines
T cell activation requires presence of antigen- presenting cell
helper t- cells stimulates B cells
cytotoxins T cell
memory t cells
Antigens and antibodies
antigens
generally larger & more complex molecules
protiens that trigger immune response
antibodies
carried by body fluids
Five types of antigens: IgG, IgA, IgM, IgD, IgE
secreted by plasma cells
Cells involved in the immune system
lymohocytes
Bone marrow: most of the cells of immune system are produced as immature or stem cells.
Stem cells: differentiate and mature into the different cells of the immune system.
Thymus: An organ in chest which instructs immature lymphocytes to become mature T-lymphocytes.
B-Cells: lymphocytes in the bone marrow and turn produce immunoglobulins (antibodies).
Cytotoxic T-cells: mature in the thymus and are responsible for killing infected cells.
Helper T-cells: “help” other T-cells and B-cells to perform their functions.
Plasma Cells: develop from B-cells and that make immunoglobulin for the serum and the secretions.
Immunoglobulins: (antibodies)
Disorders associated with the Immune system
type 1 diabetes
arthritis
lupus
HIV
