Tracheal system in cockroach

Cockroach belongs to phylum Arthropoda under invertebrate.
They have specially developed tracheal system for respiration
The system consists of series of tubes called trachea.
The Trachea opens out through 10 pairs of valvular lateral spiracles.
Each spiracle opens into a chamber called atrium.
From each atrium a tracheal tube arises.
All tracheal tubes on a side join and form a longitudinal tracheal trunk
Trachea divides into fine branches called tracheoles
The tracheoles carry oxygen directly to the cells and tissues.
The oxygen from air enters through spiracles, atria, trachea, and tracheoles and diffuses directly into the cells found in tissues.
CO₂ formed in the cells diffuse out through tracheoles, trachea, atrium and spiracles
In this method blood is not required for the exchange of gases.
