No, the only spiracles are on the abdominal segments. Those open up th large tracheal tubes.

on the lower sides of each segment
Millipedes have two pairs of spiracles on each segment that they breathe through. The spiracles open into an internal pouch and connects to the trachea.

Honey bees have ten spiracles (breathing pores). Three are on the thorax, and seven on the abdomen. The spiracles are the openings to the trachea, which expand and collapse like lungs in response to abdominal wall movement. Two large sacs in the abdomen and smaller ones in the head and thorax lead to very small breathing tubes with blind ends which are filled with liquid which absorbs oxygen and which diffuses into the tissues.
That is correct. The thoracic spine consists of 12 vertebrae that run from the base of the neck to the bottom of the rib cage. Each thoracic vertebra is connected to a pair of ribs that protect the organs in the chest cavity.
cervical, thoracic, lumbar and sacral.
The thoracic section of the vertebrae include 12 bones, one for each set of ribs.
By a tracheal system as in insects, with branched air tubes . A pair of spiracles allows air to enter each segment
Larvae breathe through spiracles located on the eighth abdominal segment.
twelve, 1 vertebrae for each set of ribs.
Just like other insects they breath through spiracles in their abdomen. Since they are relatively large insects diffusion alone is not sufficient hence they visibly contract their body in order to 'exhale'. Every segment on the abdomen has two spiracles; the ones in the second segment are also used to produce the hissing sound. Since insects have no blood circulation, miniscule tubes connected to the spiracles provide cells directly with oxygen.
