Immunity is the body's ability to resist infection. There are three main types of immunity: innate immunity which everyone is born with; adaptive immunity which develops when exposed to diseases; and passive immunity which is temporary and borrowed from another source like antibodies from a mother. Adaptive immunity involves lymphocytes and develops as a person is exposed to diseases or vaccinated. Innate immunity provides non-specific protection to entire species or races while adaptive immunity provides specific protection to species and individuals.

3. IMMUNITY IS THE MICROBIOLOGICAL
SENSE IS THE CAPACITY OF THE BODY
TO RESIST INFECTION

4. DISCOVERY OF IMMUNITY
In 1796
Doctor Edward Jenner

5. KEY CONCEPT OF SPECIFIC IMMUNITY
An antigen is a molecule that provide a
specific immune response.
Antigen are large complex molecule such as
protein
A large antigen is a molecule that have
several part

6. GENERAL THREE TYPE OF IMMUNITY
1.Innate immunity
2.Adaptive immunity
3.Passive immunity

7. INNATE IMMUNITY
Everybody is born with innate
immunity system
Non specific: species , Racial ,
Individual
Specific : species , Individual

8. ADAPTIVE IMMUNITY
The second kind of immunity of protection is
adaptive immunity
Adaptive immunity involves the lymphocytes
Develop as people are exposed to disease
Or immunized against disease through
vaccination

9. PASSIVE IMMUNITY
Passive immunity is borrowed from another
source
And its last short time for E.g antibody in
mother breast provide a temporary
immunity

10. THE COMPLEMENT SYSTEM
The first part of the immunity system
The protein freely flow to freely the blood
And freely reach to the site of infection

11. TYPE OF IMMUNITY
Immunity are mainly two type
1.Natural immunity
2.Acqired immunity

12. NATURAL IMMUNITY
Species
Race
Individuals

13. ACQUIRED IMMUNITY
Active immunity
Passive immunity

14. ACTIVE IMMUNITY
Natural acquired immunity
Artificial acquired immunity

15. PASSIVE IMMUNITY
Natural acquired immunity
Artificial immunity

16. NATURALLY ACQUIRED IMMUNITY
After clinical infection
After sub clinical infection
