THE LYMPHOID-IMMUNE
SYSTEM
- IMMUNE
SYSTEM
- FUNCTIONS
- Protect against disease
or other pathogens.
- Through a series of
steps called the immune
response, it recognizes
and attacks pathogens.
- It´s the body's defense
against infectious organisms
and other invaders. It attacks
organisms and substances
that invade body systems.
- IMMUNITY
- Active
- Passive
- LYMPHATIC
SYSTEM
- FUNCTIONS
- Drain the excess of
intersitial fluid from
tissue and blood
- Fluid brought by pressure
differences between blood
vessels and intersitial space.
When this fluid enters the
lymphatic vessels it is soon
called lymph.
- lipid
transport
- Lymphatic capillaries in the
small intestine known as
lacteals absorb dietary lipids.
- Disease resistance
- B cells and macrophages
in the lymph nodes and
spleen produce
antibodies that mark and
destroy antigens
- It is a network of
vessels that contain and
transport lymph
- ORGANS
- Spleen
- Filters the blood. It removes old
or damaged red blood cells. It
also triggers the release of
lymphocites.
- Tonsils
- Help fight infections.
- Appendix
- Releases some mucus
into the large intestine.
- Lymph node
- Filters lymph
- Thymus
- Immature lymphocytes first
go to its cortex to become
T cells, but their maturation
finishes in the medulla.
- Bone marrow
- Production and early selection
of lymphocytes.
- Peyer’s patches
- Contain mostly B cells.
- Lymphatic vessels
- Carry lymph from the body's
tissues to the blood vessels
and heart.
- MALT
- immune cells located
diffusely in the
digestive, respiratory,
or urogenital
mucosae
- Gut
- Bronchus
- Nasal
- Conjunctival
- Organized mucosa
- Diffused mucosa
- Skin
- Larynx
- LINES OF DEFENSE
- FIRST
- SKIN
- MUCUS
- Prevent pathogens from
entering / Non-specific
response
- SECOND
- INFLAMATORY RESPONSE
- Makes macrophages travel
faster/ Tissue repair
- MACROPHAGES
- Destroy pathogens
- Non-specific
response
- THIRD
- B CELLS
- For bacterial pathogens
- ANTIBODIES
- Identify and neutralize
antigens in the body
- T CELLS
- For viruses or cancer
- Specific response
