Immune System Flashcards
Source of stem cells, leukocytes, and maturation of B lymphocytes
Bone marrow
Specific protein produced in humoral response to bind with antigen
Antibody
Gland located in the mediastinum, large in children, decreasing size in adults; site of maturation and proliferation of T lymphocytes
Thymus
The immune system consists of
4 components
- lymphoid structures
- immune cells
- tissues for immune cell development
- chemical mediators
What includes the lymph nodes, spleen and tonsils, the intestinal lympho
Lymphoid structures
What 2 components provide the specific mechanism for the identification
- Immune cells/lymphocytes
- Macrophages
All immune cells originate here
Bone marrow
Tissues involving immune cell production and development include the:
2 sites
- bone marrow
- thymus
Test which assesses the levels and functional quality of serum immunoglobulins or amount of specific antibodies
Titer
__________ immunity is species specific
Natural
________ immunity is gene specific and related to ethnicity
Innate
How many steps are there in th immune response? What are they?
- 2
- Primary and secondary
Type of Acquired Immunity
Pathogens enter the body cause illness: antibodies form in host
Natural active
Type of Acquired Immunity
Vaccine is injected into person: no illness results, but antibodies form
Artificial active
Type of Acquired Immunity
Antibodies passed directly from mother to child providing temporary protection
Natural passive
Type of Acquired Immunity
Antibodies injected into a person (antiserum) to provide temporary protection or minimize severity of infection
Artificial passive
Type of Tissue or Organ Transplant
Transferred between members of the same species but may differ genetically
One human to another
Allograft (homograft)
Type of Tissue or Organ Transplant
Transferred between 2 genetically identical bodies
Identical twins
Isograft
Type of Tissue or Organ Transplant
Transfer from one part of the body to another part on the same individual
ie Skin or bone
Autograft
Type of Tissue or Organ Transplant
Transfer from a member of one species to a different species
ie pig to human
Xenograft (heterograft)
