Lymphatic/Immune System Naidelin Alvarez 5th period - Coggle Diagram
Lymphatic/Immune System Naidelin Alvarez 5th period
Functions
Lmyphatic System
Return fluids/leaked proteins to blood
drain excess fluid
body defense
resistance to diseases
Immune System
body defense
fight infectious pathogens
keeps pathogens out
attacks those enter the body
Anatomy of Lympatic system
Lymphocytes
Thymus
behind the sternum
shrinks in size during lifetime
Lymph nodes
Lymh
moves towards the hear
no pump
carried by the lymphatic vessels
Immune defenses
Adaptive (acquired)
Specific
respond rapidly
species resistance
"born with it"
mechanical Bariiers
natural killer cells
Innate (Natural)
develop slowly
non
Body Learns
carried out by lmyphoctyes
Natural acquired active immunity
occurs after exposure to antigen
Artificially acquired active immunity
Through the use of vaccines
Artificially acquired passive immunity
the injection of gamma globulin containing antibodies
Responses
Cellular Response
activated T cells
interact directly with antigen-bearing cells
cell-to-cell contact
Humoral response
T cells become memory B cell
respond to future encounters with antigen
producing & secreting antibodies
Antigens
proteins polysaccharides
glycoproteins
glycolipids trigger IS
Pathogen can trigger IS
Antibodies
Immunoglobulins
soluble protein
secreted by plasma cells
derived from B cells
Cell Involved
Cytokines
signal cells
communicate with other cells
chemokine
related by infected cells
to start an immune system
