Respiration in insect - cockroach, Biology
N IN INSECT (COCKROACH)
Respiration is direct. So metabolic rate is high.
This system is related to each cell of the body so respiratory pigment is absent.
Unit of respiratory system is trachea. These are white thread like form net in body.
Ectodermal in origin. In wall of trachea taenidia present.
These are complete rings made up of cuticle, maintain diameter of trachea.
Branches of trachea near organs are tracheoles in their wall rings are absent.
Diameter is less. Walls are elastic. Lumen is narrow. Thin cuticle is tracheoline.
At the point of origin of tracheoles, tracheole cell present.
In the end of tracheoles, tracheole fluid is filled, helpfull in exchange of gases.
All trachea are originated from 3 pairs of tracheal trunks D, V & L.
Lateral tracheal trunk is thickest one only this opens out side by 10 pairs of spiracles or stigmeta.
2 pairs thoracic spiracles are present. 8 pairs abdominal spiracles are present.
1st pair thoracic spiracle present between prothorax and mesothorax.
2nd pair thoracic spiracle present between meso and metathorax.
8 pairs abdominal spiracle present in first 8 segments of abdomen. Spiracles are ectodermal in origin.
All spiracles present on lateral side, except 1st abdominal spiracle or 3rd spiracle.
Near to spiracle Peristigmetal gland present. Each spiracle is protected by a plate i.e., peritreme.
Cavity of spiracle is atrium. In it bristles present to check dust particles.
By the outgrowth of wall of atrium a valve is formed. Controls opening and closing of spiracle.
1st thoracic and 1st abdominal spiracles always remains open, rest open or close during process.
