The ability of the body to resist foreign invaders.

Immunity (correct)

Acquired Immunity

Humoral Immunity

Cellular Immunity

Results from the general and physiological processes occurring in an individual.

Acquired Immunity

Humoral Immunity

Cellular Immunity

Innate Immunity (correct)

Examples of Innate Immunity are listed below except:

Phagocytosis of bacteria

Destruction of organisms by some compounds like Lysozyme, Complement system, and natural killer lymphocytes

Destruction of swallowed organism by acid secretions and digestive enzymes

Formation of activated T lymphocytes or sensitized T cells (T helper cell, Cytotoxic /killer T cell, and Suppressor T cell/ regulatory T cell) (correct)

Develops unless foreign body invades the individual thru active/passive Immunization.

These are also called immunoglobulins (Ig)

Antibodies Signup and view all the answers

The antibody is a Y shaped structure having two portion:

Variable portion (light chain part) and Constant portion (heavy chain part) Signup and view all the answers

It is responsible for the attachment of antigen.

Variable portion (light chain part) Signup and view all the answers

It is responsible for the activation of the compliment system.

Immunoglobulin (commonly found in body secretions like tears and saliva)

IgA Signup and view all the answers

Bivalent Ig (antibodies with two binding site for attachment of antigen); most numerous immunoglobulins present in the serum

IgG Signup and view all the answers

Polyvalent Ig (antibodies with ten binding site ); First response Ig; Large Ig

IgM Signup and view all the answers

Bivalent Ig; numerous in cases of allergic and parasitic reactions

IgE Signup and view all the answers

These are substances having a molecular weight of more than 8000, were termed “foreign bodies” because they are not normally present in the body. Examples: could be bacteria and viruses

When allergic reaction occurs in an individual, it is characterized with the presence of large quantities of:

Regulates the activity of Cytotoxic T Cell

T helper cells and Suppressor T cells Signup and view all the answers

Can kill even the normal cells if not controlled properly.

Cytotoxic/Killer cells Signup and view all the answers

Responsible for the formation of Immune tolerance of an individual.

Suppressor T cells Signup and view all the answers

Produced in the body will kill the normal cells within the body. During their development, they are introduced to the normal T cell so that they will not kill/destroy the normal cell.
