8.0 Respiratory systems in humans and animals

Inhalation in Insect

• abdominal muscle relax

• volume of trachea increase

• this reduces the air pressure in trachea

• higher atmospheric air pressure pushes the air into the trachea through the spiracle

Exhalation in Insect

• abdominal muscle contract

• volume of trachea reduced

• this increases the air pressure in trachea

• air is forced out through spiracle

Let's recall the respiratory system first!
