Lymphatic System and Immunity
1 recirculates interstitial fluid
2 Components of Lymphatic System
2.1 Lymphatic Capillaries
2.2 Lymphatic Vessels
2.3 Lymph Nodes
2.4 Lymphatic Trunks
2.5 Lymphatic Ducts
2.6 Primary Lymph Organs
2.6.1 Thymus - T-Cells are formed

Annotations:

  • what is inveloom?
  • The thymus is where t and b cells mature
2.6.1.1 Hangs over heart, largest at puberty, shrinks as we age, makes t-cells, immunocompitent
2.6.2 Red Bone Marrow - B- cells
2.7 Secondary Lymph Organs and Tissues
2.7.1 Spleen

Annotations:

  • holds platelets- w/o spleen clotting can become problematic
2.7.1.1 White and red pulp; platelets are stored here; white-lymphatic tissue; old rbc's are destroyed here
2.7.2 Lymph Nodes
2.7.2.1 Scattered along lymphatic vessels; superficial and deep; serve as filters
3 Lymph- Clear, Milky interstitial Fluid in the lymphatic system
4 lymph moves the same way that blood moves-body facilitation

Annotations:

  • lymph fluid moves by respitory pump
5 Afferent Vessels- going in

Annotations:

  • There are more Afferent vessels then efferent, this is to give the B and T cells a chance to attack.
6 Efferent Vessels - going out

Annotations:

  • Less of these, and they leave the lymph node through the hilum (indentation)
7 Immune Response
7.1 Innate

Annotations:

  • 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
7.2 Adaptive (aquired)

Annotations:

  • 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
7.2.1 Cell mediated
7.2.2 Antibody Mediated
8 right side is lymphatic; left side is thoracic

Annotations:

  • the sides of the lymphatic system
9 Lacteals

Annotations:

  • Specialized lymphatic capillaries
10 chemotaxis

Annotations:

  • wandering macrophages
11 Natural Killer Cells

Annotations:

  • "Terminator" cells - goes after cancer cells without hesitation - the theory is that we are born with only so many
12 Interferons

Annotations:

  • The beta ones are used to treat and to slow the progress of MS
13 Phagocytosis

Annotations:

  • There are 5 steps: Chemotaxis, Adherence, Ingestion, Digestion, Killing
