control.

vaccination
The process by which harmless
antigens are deliberately introduced
into a persons body to produce
active immunity.
vaccine
(pl. vaccines)A substance used in a vaccinationthat consists of pathogens that have
been weakened or killed but can still
trigger the immune system intoaction.

inflateTo fill with air or gas so as to make it
swell.
deflateTo release air or gas.
lungsThe main organs of the respiratory
system. Your lungs are a pair of large

lymph nodeLymph nodes are small, bean-shaped glands throughout
the body. They are part of the lymphatic system, which
carries fluid (lymph fluid), nutrients, and waste material
between the body tissues and the bloodstream. The
lymphatic system is an important part of the immune
system, the body's defense system against disease. The
lymph nodes filter lymph fluid as it flows through them,
trapping bacteria, viruses, and other foreign substances,
which are then destroyed by special white blood cells
called lymphocytes.

An act of breathing where air is
inhaled and exhaled.
T cell
A lymphocyte that identifies
pathogens and distinguishes one
pathogen from the other.
lymphocyteA smallwhite blood cell (leukocyte) that plays a
large role in defending the body against disease.
Lymphocytes are responsible
for immune responses. There are two main types
of lymphocytes: B cells and T cells. The B cells
make antibodies that attack bacteria and toxins
while the T cells attack body cells themselves whenthey have been taken over by viruses or have
become cancerous.
