The lungs are small and occupy only the dorsal portion of the thoracic cavity. The newly hatched insect closely resembles the parent, and the wing-rudiments appear externally on the second and third thoracic segments; but before the final moult the nymph remains quiescent, taking no food.
The thoracic cavity contains three internal chambers: a single pericardial cavity and a pair of pleural cavities (Figure 1-11a). These cavities are lined by shiny, slippery serous membranes. The heart is surrounded by the pericardial cavity.The relationship between the heart and the cavity resembles that of a fist pushing into a balloon (Figure 1-11b). The wrist corresponds to the base (attached portion) of the heart, and the balloon corresponds to the serous membrane that lines the pericardial cavity.The serous membrane is called the pericardium. cut that passes along the midline and divides the body into left and right halves is a midsagittal section, or median section; a cut parallel to the midsagittal line is a parasagittal section. Body Cavities. Many vital organs are suspended in internal chambers called body cavities.
