The orderly movement of epithelial cells during development of an open tracheal system. An example of this is found in Drosophila melanogaster. The process whose specific outcome is the progression of an organismal system over time, from its formation to the mature structure. A system is a regularly interacting or interdependent group of organs or tissues that work together to carry out a given biological process. The process by which the anatomical structures of a spiracle are generated and organized. Spiracles are the openings in the insect open tracheal system; externally they connect to the epidermis and internally they connect to the tracheal trunk. The process whose specific outcome is the progression of an open tracheal system over time, from its formation to the mature structure. An open tracheal system is a respiratory system, a branched network of epithelial tubes that supplies oxygen to target tissues via spiracles. An example of this is found in Drosophila melanogaster. Process by which a cell becomes capable of differentiating autonomously into an epithelial cell within an open tracheal system regardless of its environment; upon determination, the cell fate cannot be reversed. Tracheal cells are set aside as 10 clusters of approximately 80 cells on each side of the embryo (termed tracheal placodes). An example of this is found in Drosophila melanogaster. The progression of the respiratory system over time from its formation to its mature structure. The respiratory system carries out respiratory gaseous exchange. The projection of branches of an open tracheal system towards their target tissues. An example of this is found in Drosophila melanogaster. Formation of the tracheal sacs, the first tube-like structures to form in the open tracheal system. Once cells are determined to their tracheal cell fate, the tracheal sacs arise by invagination of each ectodermal cluster of tracheal placode cells, between 5 and 7 hours after egg laying. An example of this is found in Drosophila melanogaster. Allocation of a set number of cells to each primary branch in an open tracheal system, prior to the onset of cell migration. This establishes different domains of cells within the tracheal placode. Ensuring that tracheal cells form and maintain tubular structures with the correct size and shape for their position in the network. This is essential for efficient flow of gases through the tracheal network. The process by which the anatomical structures of branches in the open tracheal system are generated and organized. Morphogenesis pertains to the creation of form. The clearance of liquid from the epithelial tubes of an open tracheal system, shortly before the emergence of the larva, to generate an air-filled tubule system. Allocation of epithelial cells within each migrating branch in an open tracheal system to distinct tracheal cell fates. During the migration phase each branch forms a well-defined number of cell types (including fusion cells, terminal cells and branch cells) at precise positions. Growth of epithelial tubes that originate from pits in an open tracheal system and grow towards each other to meet and form a continuous open tube called the dorsal trunk. The dorsal trunk extends from the anterior spiracle to the posterior spiracle of the larva and forms the main airway of the insect tracheal system.
