ANATOMY OF THE RESPIRATORY SYSTEM
Respiration is defined as the exchange of gas between an
organism and its environment. The respiratory system
consists of a gas-exchanging mechanism supported and
protected by a bony cage.
Gas exchange is carried out by the lungs, while the ribcage
performs a protective function.
• The lungs are housed within the
thorax, an area bounded in the
superior aspect by the first rib
and clavicle, and in the inferior by
the twelfth rib.
• The lateral and anterior aspects
are composed of the ribs and
sternum.
• The entire thorax is suspended
from the vertebral column.
, The framework of Respiration includes
• Bony Thorax
• Visceral Thorax
• Muscles of Respiration
