2.44 describe the structure of the thorax, including the ribs, intercostal muscles, diaphragm, trachea, bronchi, bronchioles, alveoli and pleural membrane

The Thorax:

·         Is incased by the rib cage which has intercostal muscles in between the ribs and the diaphragm underneath

·         Inside the ribcage are two lungs

·         The air is brought through the trachea to the bronchi

·         The air travels to the bronchioles until it reaches the alveoli where the capillaries in the pleural membrane exchange the carbon dioxide with oxygen to use for cell respiration
