Structure of the Respiratory system
Epiglottis
Prevents food or fluids entering the trachea
Intercostal muscle
Located between the ribs
Helps increase and decrease the space in the chest cavity (Thorax)
Trachea
Flexible during breathing
Strong and flexible Cartilage to support and protect
Larynx
Enables speech and sound
Bronchus
Delivers air from the Trachea
Warm, moistened and cleans the air
Pleural Membranes
Creates surface tension
Prevents lungs from collapsing during expiration
Alveoli
sacs at the end of Bronchioles
Gas Exchange
Flexible to allow air flow
Diaphragm
Domed shaped -which separates the Thorax from the Abdominal Cavity
During expiration The diaphragm relaxes moving upwards
During inspiration the diaphragm contracts moving downwards
Bronchiole
Deliver air from the Bronchi to the Alveoli
Regulate air flow
