4 The Immune System
5 Humoral Immunity
1 Humoral Immunity
Also known as B lymphocytes, B cell carry out a version of specific immunity called humoral immunity. During humoral immunity, B cells produce and secrete antibodies into our body tissue cavities.
2 Classes of Antibodies
antibodies: Specific protein markers that are created by the immune system for binding and reacting to specific antigens; antibodies are created by B cells during humoral immunity.
There are five classes of antibodies. Membrane-bound antibodies include IgE, IgD, and IgM. Secreted antibodies include IgG and IgA.

3 Innate Immunity
Also known as non-specific immunity, innate immunity consists of general physiologic responses (fever, inflammation, etc.) that can affect the entire body.
4 Adaptive Immunity
Also known as specific immunity, adaptive immunity is carried out by T & B lymphocytes and reacts to specific antigens of cells; adaptive immunity also produces memory cells to target the same pathogen if we are ever exposed to it again.
2 Physical Barriers
Consists of skin and mucous membranes, physical barriers are our first line of defense against pathogens. Physical barriers are part of our non-specific immunity.
1 Pathogens
Any disease-causing agent that we are exposed to (bacteria, virus, fungus, parasite, etc.)

6 Cell-Mediated Response
1 Cell-Mediated Response
A type of adaptive immunity in which T cells respond to target cells that have been infected by pathogens.
2 The Process
- Dendritic cells engulf the virus.
- Helper T cells monitor the dendritic cells.
- The correct helper T cell is activated.
-
- The cell-mediated immune response multiplies.
