Lymphatic
System
and
Immunity
- recirculates interstitial fluid
- Components of Lymphatic System
- Lymphatic Capillaries
- Lymphatic Vessels
- Lymph Nodes
- Lymphatic Trunks
- Lymphatic Ducts
- Primary Lymph
Organs
- Thymus - T-Cells
are formed
Anmerkungen:
- what is inveloom?
- The thymus is where t and b cells mature
- Hangs over heart, largest at
puberty, shrinks as we age,
makes t-cells,
immunocompitent
- Red Bone Marrow -
B- cells
- Secondary Lymph Organs
and Tissues
- Spleen
Anmerkungen:
- holds platelets- w/o spleen clotting can become problematic
- White and red pulp;
platelets are stored here;
white-lymphatic tissue; old
rbc's are destroyed here
- Lymph Nodes
- Scattered along lymphatic
vessels; superficial and
deep; serve as filters
- Lymph- Clear, Milky interstitial Fluid in the
lymphatic system
- lymph moves the same
way that blood
moves-body facilitation
Anmerkungen:
- lymph fluid moves by respitory pump
- Afferent
Vessels-
going in
Anmerkungen:
- There are more Afferent vessels then efferent, this is to give the B and T cells a chance to attack.
- Efferent
Vessels -
going out
Anmerkungen:
- Less of these, and they leave the lymph node through the hilum (indentation)
- Immune Response
- Innate
Anmerkungen:
- We are born with this type of immunity, we get this from Mom
- At birth we have non-specific and non adaptive immunity (immune response), this includes 1st and 2nd line of defense pgs 886-888 in text
- Adaptive (aquired)
Anmerkungen:
- two types, cell mediated or antibody mediated, both are gained through vaccines
- Describes the ability of the body to adapt defenses against antigens of specific bacteria, viruses, foreign tissue.....even toxins
- Cell mediated
- Antibody Mediated
- right side is lymphatic;
left side is thoracic
Anmerkungen:
- the sides of the lymphatic system
- Lacteals
Anmerkungen:
- Specialized lymphatic capillaries
- chemotaxis
Anmerkungen:
- Natural Killer Cells
Anmerkungen:
- "Terminator" cells - goes after cancer cells without hesitation - the theory is that we are born with only so many
- Interferons
Anmerkungen:
- The beta ones are used to treat and to slow the progress of MS
- Phagocytosis
Anmerkungen:
- There are 5 steps: Chemotaxis, Adherence, Ingestion, Digestion, Killing
