Aerobic respiration is the process of
breaking down nutrients (usually glucose)
in the presence of oxygen to produce
energy (ATP), carbon dioxide, and water.
AEROBIC RESPIRATION
Anaerobic respiration is the process of
breaking down nutrients (such as
glucose) without the use of oxygen. It is a
less efficient process compared to
aerobic respiration.
ANAEROBIC RESPIRATION
Respiration is a crucial process that allows all
living organisms to extract energy from food.
RESPIRATION
OVERVIEW
Breathing involves the intake of oxygen-
rich air and the release of carbon dioxide-
rich air through respiratory organs.
Inhalation refers to the intake of oxygen,
while exhalation is the expulsion of
carbon dioxide. 
BREATHING
Exhalation is initiated by the relaxation
of intercostal muscles and the
diaphragm, causing the ribs to return to
their original position and the
diaphragm to assume a dome shape. 
EXHALATION
INHALATION
 Inhalation, an energy-demanding
process, involves the simultaneous
contraction of intercostal muscles and
the diaphragm. This action moves the
ribs outward and upward, expanding the
thoracic cavity and increasing lung
volume.
