Question
Label the icons in relation with the Respiratory system of a Cockroach:
1. ⟹ 2.⟹ 3. ⟹ 4. ⟹ 5.
1. ⟹ 2.⟹ 3. ⟹ 4. ⟹ 5.
Answer: Option B
:
B
In cockroach the passage of air flow is as follows : It enters the system by openings called Spiracles, then moves onwards into a small chamber called atrium where its pressure is regulated, from where it enters into the trachea , made of the protein trachein, and then into tracheoles (branches) and finally reaches the organs for exchange of gases, through diffusion. It returns through almost the same way, but exits out through the thoracic spiracles mainly as they are continuously open. Therefore, the correct option is
B.(1. ⇛ Spiracles, 2. ⇛ Atrium, 3. ⇛ Trachea, 4. ⇛ Tracheoles, 5. ⇛ Organs.)
