Cellular
Cellular has several definitions in the field
of medicine. One definition is relating to,
made from, resembling, or originating from
cells. A cell is the smallest, most basic
unit of life, that is capable of existing by
itself. Cells carry out the chemical
processes that are necessary for life to
exist. A good example of this definition of
cellular is cellular respiration, which refers
to the controlled release of energy in
cells. A second definition of cellular is
having many components, small areas, or
spaces.

For example, pock marks are pit-like scars left on the skin by some type of skin disease
such as acne scarring or chicken pox. A third definition of cellular (often referred to as
cellular immunity) means relating to, or being part of immunity or the immune response
that is influenced mostly by T cell lymphocytes, which are specialized cells that help
provide a specific response to attack invading organisms. Immunity is when the body has
sufficient defenses in place to protect itself from infection, disease, or other biological
attacks. The immune response is when certain cells of the body try to defend it from
harmful substances. Cellular comes from the Latin word "cella" meaning "storeroom."
