Q

Lymphatic System: Functions

A
  • Reduces tissue edema (swelling)
  • Returns proteins from interstitial fluid back to blood
  • Traps and Filters cellular debris and foreign substance; bacteria, toxins, cancer cells, viruses, pathogens
  • Recycles body fluid
  • Circulates lymphocytes to assist with immune function
  • Transports fats from GI tract back to blood stream

Q

Immune System: Functions

A
  • Protects the body from foreign invasion
  • Coordinates activities in the blood stream, tissues, and lymph to protect body from invasion
  • Fights infection and protects against future infections by producing antibodies and immune cells
  • Production of immunoglobulin (Antibodies)

Q

Lymph Pathways

A

Vessels that transport lymph fluid

 - Lymph capillaries
 - Receive fluid and debris 
 - Moves one way, toward heart
 - Valves encourage one way flow

Q

Lymph Nodes

A
  • Located near joints
  • Filter foreign substances
  • Primary Filtering agents:
    • Macrophages
    • Lymphocytes

No lymph nodes in CNS

Q

Cells of Immune System

A

Stem Cells produce:

 - Lymphoid 
 - Myeloid
  • Lymphoid produce:
    • Lymphocytes
      • B Cells
      • T Cells
  • Myeloid produce:
    • Granulocytes
      • Neutrophils
      • Eosinophils
      • Basophils

25
Cytotoxic T Cells
Engulf and kill cancer and infected cells
26
Helper T Cells (T4)
Activate B Cells and Cytotoxic T Cells - Affected by HIV
27
From Leukocytes
Neutrophils - Phagocytes Basophils - Inflammation Eosinophils - Parasite Infection Lymphocytes - Specific Immune Response
28
Neutrophils
Engulf bacteria and cellular debris; Frontline of immunity - Myeloid
29
Lymphocytes
Produce Antibodies and regulate immune response (B & T Cells) - Specific Immunity
30
Monocytes
Associated with engulfing cellular debris, antigen processing
31
Eosinophils
Associated with parasitic infection and allergic response | - Myeloid
32
Basophils
Associated with hypersensitivity and release histamine
33
Helper T Cells
Used to activate B Cells to release antibodies to go fight pathogen
34
Defense Against Pathogen
Pathogen: Disease producing agent Mechanical & Chemical Defenses: - Skin; Mucus Membranes, Cilia - Gastric Juices Natural Immunity: - Natural resistance to certain disease Acquired Immunity: - Exposure to pathogen or vaccination - Humoral and Cell Mediated
35
Humoral Immunity
B cells which become plasma cells: - Secrete immunoglobulin (antibodies) - IgG: Bacteria, virus, toxins activate this antibody - IgA: In breast milk, tears, nasal fluid, saliva, gastric juice - IgM: Bacteria, virus' activate this antibody first - IgE: Important in Allergic Reaction
36
Cell Mediated Immunity (T Cells)
- Acquired active immunity: by T Cell action - T Cells specific to antigen - Reproduce and secrete cytokines / lymphokines - T Cells also activate B cells which secrete antibodies - Helper T Cells: T4 that stimulate immune response - Cytotoxic T Cells: T8 destroy infected cells
