EXAM U7 U8
Immune System & Hereditary Diseases
Resistance/protection from an individual's environment
: 'chemical system'
: T-cells & B-cells
Antigen -vs- antibody response
Any substance foreign to the host
: induces immune response & reacts w/antibodies
Incomplete or 'hapten'
: reacts w/antibody. But does
elicit immune response w/o being coupled w/another antigen or cell.
Substance raised in self as an antagonist to the antigen.
: family of '
Produced in plasma cells
: lymphocytes capable of producing antibody)
: originate in bone marrow & lymphoid tissue of the alimentary tract.
Lymphocytes that mature in the thymus
Four different types
: T-helper; T-suppressor; Cytotoxic T-cells; & Natural Killer cells
Delivers antigen to B-cell
Diminishes excess antibody production
Kill cells that process foreign/altered antigens.
"Natural Killer cells"
Capacity to spontaneously kill various target cells
Capable of binding to & killing virus-infected & tumor cells.
Mechanism not understood
* Process of Immunity
Reticular Endothelial (RE cells)
: break down antigens
1) 'monocyts' & 'macrophages'
: their presence stimulates lymphocyte production.
Pieces are presented to T-cells
