apparatus

Anatomy
An integrated group of structurally and functionally linked parts (including muscles, nerves, blood and lymphatic vessels, glands, stroma and so on) which act in concert to perform a particular function, as in digestion, which is performed by the alimentary apparatus (now preferentially known as the GI tract).

The use and translation of the anatomic term apparatus has proven problematic, as each information consumer views the scope (structure and function) of an apparatus in a distinct manner, and there are number of translations thereof (i.e., organs, system and tract).
 
The traditional and formally sanctioned uses of the term apparatus notwithstanding, ultimately the term system (as applied to the digestive, respiratory and urogenital apparatuses) is increasingly preferred.

Technology
A structurally and functionally integrated device used to perform a particular task.
