2. Immunity
Is the capability of multicellular organisms to resist
harmful microorganisms form entering it.
or
The ability of organisms to defend the cells from
both internal and external complications.

3. Specific Immunity
cont.
• Definition.
• Introduction.
• Types:
a). Active or natural immunity.
b). Passive or artificial immunity.
• Specific defense mechanism:
a). Cell-mediated immune response.
b). Antibody mediated immune response.

4. Specific Immunity
• Definition:
The adaptive immune system of the body
is specific immunity.

5. Specific Immunity
Intro.
• Also known as acquired immunity
• Subsystem of overall immunity
• Composed of highly specialized cells
• Processes that eliminate pathogens or prevent
their growth.
• Not present by birth
• Developed by the infection or vaccine.

6. Types of Specific Immunity
* Active/Natural Immunity:
. Long lasting immunity
. Developed by antibodies produced by Individual
own cells.
e.g chickenpox, mumps, measles.

7. Types of specific Immunity
• Passive/Artificial Immunity:
. Borrowed from another source
. Lasts for short time
for example….
Antibodies in mother`s Milk.

8. Specific Defense Mechanism
• Two main responses are involved in this
mechanism…
a). Cell mediated immune response:
. T cells originate in bone marrow
. Move to thymus for development
. Highly specialized cells in Blood

9. Cell mediated
• Three kinds of T cells
• 1. cytotoxic T cells.
• 2. Helper T cells.
• 3. Suppressor T cells.

10. Antibody Mediated
• It consist of B-cells
• originate in bone marrow
• Stay there to develop
• Can produce antibodies.
