How do insects Breathe.
  • 1 answers

Yogita Ingle 6 years, 10 months ago

Insects do not have lungs or any pulmonary system like most vertebrates. Instead, they have a series of holes along the sides of their thorax (middle section) that branch off into many smaller and smaller tunnels, much like veins branch off into capillaries to carry oxygenated blood all over the body. These holes are called spiracles.
