What are the 4 subunits of an antibody?

2 heavy chains and 2 light chains

What are the physical and chemical components of innate immunity?

Skin + Mucous Membranes

What are the cellular components of innate immunity?

(Phagocytic Cells) - Granulocytes, Monocytes, Macrophages, and Natural killer cells

What are soluble factors of innate immunity?

Complement proteins + cytokines

What are the four types of T - Cells ?

Helper T-cells, Cytotoxic T-cells, Regulatory T-cells, Memory T-cells.

What are the 4 ways to acquire adaptive immunity?

Natural Active, Natural Passive, Artificial Active, Artificial Passive

What is natural active acquired immunity?

The body becomes immune after being naturally exposed to a pathogen, gets sick, and then recovers.

What is natural passive acquired immunity?

Antibodies are passed from mother to child without the mother or child's immune system actively creating them.

What is Artificial active acquired immunity?

Your body produces its own antibodies in response to a weakened or dead form of a pathogen introduced through a vaccination.

What is artificial passive acquired immunity?

Antibodies are given directly to a person to provide immediate, temporary protection. This is done by injecting antibodies (immunoglobulin) produced in another person or animal.

What triggers antibody productions?

B-cell encounters its specific antigen, it becomes activated and begins to multiply

What part of the antibody combines with the antigen?

The variable region

True or false: red bone marrow, spleen, lymph node, and thymus are all part of the immune system?

True

• IgM

• IgE

• IgG

• IgA

These are all classes of what?

Antibodies

True or false:

-Release of inflammatory chemicals

-inactivation of the antigen

-phagocytosis of the antigen 

are all the effects of the antigen + antibody combining?

True

Does fluid balance happen in the lymphatic system?

Yes, fluid balance happens in the lymphatic system

Does defense against pathogens happen in the lymphatic system?

Yes, defense against proteins happens in the lymphatic system.
