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. The process by which the anatomical structures of a tube are generated and organized. Morphogenesis pertains to the creation of form. Epithelial and endothelial tubes transport gases, liquids and cells from one site to another and form the basic structure of many organs and tissues, with tube shape and organization varying from the single-celled excretory organ in Caenorhabditis elegans to the branching trees of the mammalian kidney and insect tracheal system. Fusing of specific tracheal branches in an open tracheal system to branches from neighboring hemisegments to form a continuous tracheal network. Branch fusion is mediated by individual cells at the tip of each branch, which contact a similar cell and undergo a coordinated series of morphogenetic events that create a bicellular fusion joint. The process by which the anatomical structures of branches in a tube are generated and organized. Morphogenesis pertains to the creation of form. A tube is a long hollow cylinder. The process by which the anatomical structures of a tube are generated and organized from an epithelium. Morphogenesis pertains to the creation of form. Epithelial tubes transport gases, liquids and cells from one site to another and form the basic structure of many organs and tissues, with tube shape and organization varying from the single-celled excretory organ in Caenorhabditis elegans to the branching trees of the mammalian kidney and insect tracheal system. 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 joining of specific branches of a tubular system to form a continuous network.
