Breathing
Breathing
is the process that moves air in and out of the
lungs
, or oxygen through other
respiratory organ
s such as
gills
. For organisms with lungs, breathing is also called
ventilation
, which includes both
inhalation
and
exhalation
. Breathing is one part of
physiological respiration
required to sustain
life
.
Aerobic
organisms
of birds, mammals, and reptiles—require oxygen to release energy via
cellular respiration
, in the form of the
metabolism
of energy-rich
molecules
such as
glucose
. Breathing is only one of the processes that deliver
oxygen
to where it is needed in the body and remove
carbon dioxide
. Another important process involves the movement of blood by the circulatory system.
Gas exchange
occurs in the pulmonary
alveoli
by
passive diffusion
of gases between the alveolar gas and the blood in
lung
capillaries
. Once these dissolved gases are in the
blood
, the
heart
powers their flow around the body (via the
circulatory system
). The medical term for normal relaxed breathing is
eupnea
.
