FBbt:00000019 metathoracic segment The third (most posterior) segment of the thorax.
FBbt:00005027 tracheal metamere 2 The tracheal system of T3.
FBbt:00000052 embryo  
FBbt:00000254 embryonic/larval transverse connective Embryonic/larval trachea that connects the dorsal and lateral trunks.
FBbt:00000211 embryonic/larval trachea Larval trachea from their maturation in late embryonic stages, to their degeneration/transformation during metamorphosis.
FBbt:00005043 trachea Cuticle-lined epithelial tube that forms part of the tracheal system. The thinnest trachea consist of a single tracheocyte folded back on itself to form a tube.
FBbt:00005574 tracheal branch primordium Developing tracheal branch of the embryo.
FBbt:00000015 thorax The main middle section of the insect body comprising three thoracic rings: the pro-, the meso- and the metathoraces which are more or less well fused and cask-like sometimes having on the upper lateral part one of two pairs of wings, while on the ventrolateral part each thoracic ring bears a pair of legs.
FBbt:00000185 embryonic/larval tracheal system  
FBbt:00000003 segment One of the repeated divisions of the whole organism.
FBbt:00001727 larva  
FBbt:00005024 tracheal system  
FBbt:00000406 embryonic/larval spiracle Any spiracle (FBbt:00005054) that is part of some embryonic/larval tracheal system (FBbt:00000185).
FBbt:00007005 epithelium Portion of tissue, that consists of one or more layers of cells with distinct apical-basal polarity, connected to each other by cell junctions.
FBbt:00005025 tracheal metamere Segmental subdivision of the tracheal system.
FBbt:00000016 thoracic segment Any segment (FBbt:00000003) that is part of some thorax (FBbt:00000015).
FBbt:00005054 spiracle Opening of the tracheal system on the surface of the body.
FBbt:00005589 spiracular branch primordium Region of a tracheal primordium that develops into an embryonic/larval spiracular branch. During stages 11 and 12, the invaginating tracheal pit forms an L shape. The arm of the L heading inwards from the surface forms the spiracular branch primordium. In all except the first and tenth tracheal metameres, the spiracular branch collapses, forming a solid cord.
FBbt:00000001 organism An individual member of the species Drosophila melanogaster.
FBbt:00007472 primary trachea Trachea that is two or more cells (tracheocytes) in circumference. During embryogenesis, primary trachea are formed from the tracheal primordium between stages 11 and 15.

FBbt:00007006 developing material anatomical entity  
FBbt:00005495 primordium Primordia are populations of contiguous cells that are morphologically distinct and already correspond in extent to a later organ/tissue.
FBbt:00007009 organism subdivision Anatomical structure that is a primary subdivision of whole organism. The mereological sum of these is the whole organism.
FBbt:00007001 anatomical structure Material anatomical entity that has inherent 3D shape, whose parts are all connected and that is generated by coordinated expression of the organism's own genome.
FBbt:00007330 organ system subdivision

FBbt:00004856 organ system A division of the whole organism into specialized systems.
FBbt:00007474 epithelial tube A tubular epithelium.
