General Information
Term	Malpighian tubule segment	ID (Ontology)	FBbt:00005789 (Fly Anatomy)
Definition	Segment of the Malpighian tubule. Each tubule can be divided into distinct segments based on differences in appearance, cell structure and function. The initial segment is involved in calcium homeostasis and excretion, the transitional and main segment are secretory and the lower tubule and ureter are reabsorptive. Type I cells are found in all segments, but Type II cells are only found in the upper tubule (initial, transitional and main segments).[ FlyBase:FBrf0030988 FlyBase:FBrf0083335 FlyBase:FBrf0128452 FlyBase:FBrf0184042 FlyBase:FBrf0202697 FlyBase:FBrf0218070 FlyBase:FBrf0222532 FlyBase:FBrf0245230 ]
