Question

how do cockroaches and other insects breathe short answer​

Answer 1

Answer:

They do this by using a very efficient breathing system that uses air filled tubes, called trachea, to deliver oxygen directly to cells. Oxygen flows in as required into the tracheal system through valves on the insect, called spiracles. But, sometimes, they shut their spiracles and stop breathing.•‿•

Answer 2

• Spiracles and tracheae allow cockroaches and other insects to breathe. An insect's body is made up of a system of hollow tubes.
• The trachea is the name given to these hollow tubes.
• Each trachea has a very small orifice that opens onto the body's surface.
• Spiracles are the scientific term for these pores.
• The skin of earthworms allows them to breathe. The earthworm's skin is continually wet, allowing it to breathe easily.
