lymphatic system
Major functions of the
Lymphatic & Immune systems
Anatomy of the lymphatic system (including vessels, nodes, MALT, spleen and thymus)
Innate/natural immune defenses and Adaptive/acquired immune defenses
humoral vs. cellular response
antigens and antibodies
disorders of the Immune system
Rheumatoid arthritis
Asthma
Diabetes type 1
return clean fluids and leaked proteins back to the blood
drain rest of the fluid from the tissue
play an essential role in body defenses and resistance to diseases
protect the body from foreign invaders
humoral
cellular
Antibodies produced by the B cells
bind to antigens
occurs inside infected cells
mediated by T lymphocytes
antigens
antibodies
capable of stimulating an immune response
distinct surface features
Y-shaped proteins produced by B cells
response to exposure to antigens
specific
non-specific
first line of defense
physical, chemical and cellular defenses against pathogens
only found in vertebrates
consists of antibodies and lymphocytes
humoral response and the cell mediated response
tailoring of the response to the particular foreign invader
waits to attacm
responds immediately
already in the body
created in response
vessels
nodes
MALT
Spleen and thymus
scattered along collecting vessels
walls overlap to form a flap
interstitial fluid leak lymph into capillaries
mucosa associated lymphatic tissue
protects digestive and reproductive tract
located on left side of abdomen next to stomach
filters blood
destroys worn out cells
act as blood resevoir
