MECHANISM OF BREATHING
INSPIRATION
Diaphragmatic contraction
(abdominal type)
mm. intercostales externi
(costal type)
Capacity of thoracic cavity is increased:
EXSPIRATION
Capacity of thoracic cavity is decreased:
• Diaphragm and mm. intercostales externi are relaxed
• Contraction of mm. intercostales interni a intimi
• Weight of thorax
• Elasticity of rib cartilages
• Elasticity of lungs
• Pressure of abdominal organs
