1. Compare and contrast the
two types of immune
response.
By: Barby Ann P. Pedregosa MLS II-A

2.  Recognizing foreign or dangerous
macromolecules
 Responding to eliminate them
 Immunity
 Ability to resist damage from foreign substances –
such as microorganisms, harmful chemicals, such
as toxins released by microorganisms; and
internal threats, such as cancer cells.

3. Innate Immunity - Nonspecific
defenses/resistance
 Immune system parts that attack any
antigen
Adaptive Immunity -Specific defenses/resistance
 Other immune cells will only respond to
one particular antigen
 Leads to an immunity = a long lasting
protection from that particular antigen

4.  All animals have innate immunity, a defense
active immediately upon infection
 Innate immunity is present before any
exposure to pathogens and is effective from
the time of birth
 Innate immunity consists of external barriers
plus internal cellular and chemical defenses

5.  Vertebrates also have adaptive immunity
 Adaptive immunity, or acquired immunity,
develops after exposure to agents such as
microbes, toxins, or other foreign substances
 It involves a very specific response to
pathogens
 There are four types: Active/Passive,
Natural/Artificial Immunity

6.  A. Active immunity is protection that is
produced by the person’s own immune system.
This type of immunity is usually permanent.
Active immunity is stimulation of the immune
system to produce antigen-specific humoral
(antibody) and cellular immunity. Unlike passive
immunity, which is temporary, active immunity
usually lasts for many years, often for a lifetime.

7.  B. Passive immunity is protection by
products produced by an animal or human,
and transferred to another human, usually by
injection. Passive immunity often provides
effective protection, but this protection
wanes (disappears) with time, usually a few
weeks or months.
Passive Immunity

8.  Natural immunity occurs through contact with a
disease.There are two types of natural immunity.
Actively acquired and passively acquired.
A. Actively acquired -When the body has already
experience an infection by that pathogen
B. Passively acquired - Antibodies pass across
placenta providing a newborn baby with immunity
against disease.Antibodies are also present in
breatsmilk.

9.  Artificial immunity develops through deliberate action
such as vaccine.There are two types: Actively
acquired and passively acquired
A. Actively acquired -This is by vaccination at a
suitable time in the person's life, not when they are
infected. Ex.TB vaccine
B. Passively acquired -The vaccine contains ready-
made antibodies which provide immediate relief by
destroying the antigens.This is given when the person
has been infected with the antigen and has no
preivous immunity. Ex. tetanus
