40. THE IMMUNE SYSTEM
 Immunology -
1. Study of the components and function of
the immune system
 Immune System -
A. Molecules, cells, tissues and organs
which provide non-specific and specific
protection against
a) Microorganisms
b) Microbial toxins
c) Tumor cells

41. BLOOD CELLS

42. THE IMMUNE RESPONSE
1. Immune response
A. Innate (non-specific)
B. Adaptive (specific)
I. Primary
II. Secondary
2. Immunity
A. State of non-specific and specific
protection
3. Acquisition of Immunity
I. Natural
II. Artificial

43. Figure 1-4
PHYSICAL BARRIER

44. DEFENSE MECHANISM OF THE
HUMAN HOST
1. Innate Mechanisms (Innate immunity)
a) First line of defense
b) Non-specific
2. Adaptive Mechanisms (Adaptive
immunity)
a) Second line of defense
b) Highly specific with memory

45. NATURAL ACQUIRED IMMUNITY
1. Active
A. Antigens enter body naturally with response
a) Innate and adaptive immune systems
b) Provides long term protection
2. Passive
A. Antibodies pass from mother to
a) Fetus across placenta
b) Infant in breast milk

46. ARTIFICIAL ACQUIRED IMMUNITY
1. Active
I. Antigens enter body through vaccination
with response of
a) Innate and adaptive immune systems
2. Passive
I. Antibodies from immune individuals injected
into body
 Referred to as
Immune serum globulins (ISG)
–Immunoglobulins (IG)

47. COLONY OF STREPTOCOCCUS BACTERIA

48. PHAGOCYTOSIS

50. PHAGOCYTES
1. Produced throughout life by the bone
marrow.
2. Scavengers – remove dead cells and
microorganisms.

51. NEUTROPHILS
• 60% of WBCs
• ‘Mobile tissues’ as they squeeze out of the
capillaries.
• Large numbers are released during
infections.
• Short lived – die after digesting bacteria.
• Dead neutrophils make up a large
proportion of pus.

52. MACROPHAGES
1. Larger than neutrophils.
2. Found in the organs, not the blood.
3. Made in bone marrow as monocytes,
called macrophages .
4. Long lived.
5. Initiate immune responses And
display antigens .

53. LYMPHOCYTES
1. Produce antibodies.
2. B-cells mature in bone marrow then
concentrate in lymph nodes and spleen.
3. T-cells mature in thymus gland.
4. B cells and T cells mature then circulate
in the blood and lymph .
5. Circulation ensures they come into contact
with pathogens and each other .

55. T – LYMPHOCYTES
1. Mature T-cells have T cell receptors which
have a very similar structure to antibodies
and are specific to particular antigen.
2. They are activated when the receptor comes
into contact with the Antigen with another
host cell
3. Ex. A macrophage membrane or an invaded
body cell. .

56. B – LYMPHOCYTES
1. Some activated B cells produce 
PLASMA CELLS.
2. These produce lots of antibodies <
1000/sec.
3. The antibodies travel to the blood, lymph,
lining of gut and lungs etc.
4. The number of plasma cells goes down
after a few weeks.
5. Antibodies stay in the blood longer.
6. Eventually their numbers go down too.

58. ANTIBODIES
1. Also known as Immunoglobulins.
2. They have heavy and light chains .
3. which are made up of polypeptides And
glycoprotein.
4. The chains are held together by disulphide
bridges.
5. Each antibody has two identical antigen
binding sites known as - variable regions.
6. The order of amino acids in the variable
regions determine the shape of the binding site.

59. WORK OF ANTIBODY
1. Some act as labels to identify the antigens for
phagocytes.
2. Some work as Antitoxins .
3. That is they block toxins of pathogen which
causing Cholera and tetanus.
4. Some attach to bacterial flagella making them
less active and easier for phagocytes to engulf.
5. Some cause Agglutination (clumping together)
of bacteria making them less likely to spread.

60. DIFFERENT
IMMUNOGLOBULINS

61. TYPES OF IMMUNOGLOBULINS
1. Five classes
a) Immunoglobulin A (IgA)
b) Immunoglobulin G (IgG)
c) Immunoglobulin M (IgM)
d) Immunoglobulin D (IgD)
e) Immunoglobulin E (IgE)
2. Based on structural differences in constant
regions of heavy chains
3. Classes have specialized effector functions

62. HYPERSENSITIVITY
1. The immunological hyersensitive reactions to
an agent give rise to various allergic condition
and autoimmune diseases.
TYPES
I. TYPE 1 – Anaphylactic Reactions
II. TYPE 2 - Cytotoxic Reactions
III. TYPE 3 - Antibody mediated Reactions
IV. TYPE 4 - Cell – mediated Reactions
V. TYPE 5 - Stimulatory/ Blocking Reactions

63. ALLERGY
1. The term allergy is used to describe an
OverReaction to substances in the environment
2. That are harmless for most people.
3. Induce an immune response that causes a
variety of symptoms in predisposed people.
4. ALLERGY is not a disease in the typical sense.
5. It is an exaggeration of the body’s natural
immune defenses.
6. Mild allergies can be annoying and severe
forms can be very serious or even deadly.

64. TYPES OF ALLERGY
1. RESPIRATORY ALLERGY
Allergic rhinoconjunctivitis,, rhinosinusitis &
Allergic asthma, which cause wheezing,
Coughing, shortness of breath, sneezing,
Rhinorrhea .
2. SKIN ALLERGY (DERMATITIS) :-
Atopic dermatitis (eczema) and contact
Dermatitis, which mainly cause skin rash.
3. OTHER ALLERGIES :-
Food allergies and insect venom, which cause
Different types of reactions that in some cases
May be life-threatening (anaphylaxis).
