The immune system is a collection of billions of cells that travel through the bloodstream. They move in and out of tissues and organs, defending the body against foreign bodies (antigens), such as bacteria, viruses and cancerous cells.There are two types of lymphocytes :B cells-produce antibodies which are released into the fluid surrounding the bodyâs cells to destroy the invading viruses and bacteria. T cells (see picture opposite) - if the invader gets inside a cell, these (T cells) lock on to the infected cell, multiply and destroy it.here are two types of lymphocytes : B cells-produce antibodies which are released into the fluid surrounding the bodyâs cells to destroy the invading viruses and bacteria.

A Function is a subroutine used to avoid writing the same code over and over again.They are different in their uses.dd a comment |. up vote 0 down vote. A mathematical function is the interface, or specification of the inputs and outputs of an algorithm. An algorithm is the precise recipe that defines the steps that may implement a function.
