Term Name:	branch fusion, open tracheal system
Synonyms:	tracheal branch fusion
Definition:	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.
