All cells require a
continuous supply of oxygen
and must continuously get rid of
metabolic waste product
,
carbon dioxide.

ventilation
or
breathing.
It is responsible for the exchange of gases between the body and the air, a process called
respiration.
External Respiration
is the process by which gases are exchanged between the blood and the air.
Internal Respiration
is the process by which gases are exchanged between the blood and the cells of the body
Cellular respiration
is the process by which cells use oxygen for
metabolism
and give off

as a waste product.
