Lymphatic system ( LEC ) Flashcards
-Fast
- present since birth
Innate Immunity
-slower
-specific
-have memory
-T cells, B cells
Adaptive memory
-Carries out immune response
-transports dietary lipids
Lymphatic system
Lymphatic vessels
To return the plasma protein and plasma to the blood stream
Lymphatic capillaries
have greater permeability compared to blood capillary
-site where stem cells divide and become immunocompetent
primary lymphatic organs
-site for immune response occur
secondary organs
where does the T cells divide and mature?
thymus gland
-destroy foreign substance by phagocytosis
lymph nodes
The spread of a diseases from one part of the body to another
Metastasis
3 main functions for spleen
-removal by macrophages
-storage of platelets
-production of blood
Where does the B cells mature?
bone marrow
cytotoxic T cells directly attack invading antigens
Cell mediated
Produce specific proteins
Antibody mediated
2 characteristics of antigens and antibodies
Immunogenicity, re-activity
-Most abundant of immunology
-most common type of antibody
-protect us from infection and remembering the pathogen that we are exposed
IgG
-15% immunoglobulin
-prevent in nasal, saliva, breast milk, intestinal fluid
-acquired by the baby
IgA
-5%
-agglutination and lysis of micro organism
-present in anti A and anti B antibodies
IgM
-.2% immunoglobulin
- silencing
-maintenance activation
IgD
-.1% of immunoglobulin
- involved in allergic and hypersensitivity
-protection against parasites/parasitic worms
IgE
-requires recognizing the foreign antigen
Triggering adaptive response
-Kill target cells bearing an appropriate antigenic complex
Cytotoxic T cells
-Hang around for years
Memory T cells
-subsequently encounter the living in your body initiates a secondary response
clinical connection
-Primary response can be naturally acquired
or artificially acquired by vaccination
immunological memory
-produce more autoantibodies
-poorer B cell response
aging
