Immunity is:

• the process of digestion in the body

• the breakdown of food into energy

• the process of cell division

• The ability to resist disease as a result of previous exposure, resulting in a specific response being mounted by lymphocytes.

• The ability to resist disease as a result of novel exposure, resulting in a non-specific response being mounted by lymphocytes.

• The ability to resist disease as a result of novel exposure, resulting in a non-specific response being mounted by macrophages.
