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

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.
Yes
Yes.
they are found on the abdomin, and parts of the thorax
Spiracles are used by grasshoppers for respiration. Air is taken in throught the spiracles and filtered by hairs in tubes called tracheae. The trachea branch out through the body eventually ending in Tracheoles where the oxygen is distributed to cells and carbon dioxide is taken out and back throught the trachea and exits the body through the spiracles
By a tracheal system as in insects, with branched air tubes . A pair of spiracles allows air to enter each segment
Lordosis typically affects the lumbar spine, causing an excessive inward curve. It is less common for lordosis to affect the thoracic vertebrae, as the thoracic spine naturally has a slight outward curve called kyphosis. Any abnormal curve in the thoracic spine can lead to pain and other symptoms.
The air openings on abdominal segments of terrestrial arthropods would be spiracles, which connect to the trachea and tracheoles to directly oxygenate tissues and remove waste gasses. The spiracles are regulated by muscles to open or close to reduce water loss.
Woodlice, which are crustaceans, typically have a segmented body that consists of 14 segments. This includes 6 head segments, 7 thoracic segments, and 1 abdominal segment. Each segment contributes to their overall structure and mobility, allowing them to navigate their terrestrial environments effectively.
Function of spiracles for sharks
No there is no cement. Sutures and wires are used for thoracic repair.
