What is head thorax and abdomen?
Most people recognize the three tagmata—head, thorax, and abdomen—as characteristic of insects. The way they appear is rooted in a division of responsibilities. The head is for orientation, ingestion, and cognitive process; the thorax for locomotion; and the abdomen for digestion and reproduction.
What is the abdomen function?
The primary functions of the abdomen consist of digestion, breathing, posture and balance, as well as movement. The major organs located in the abdomen are associated with digestion, for which the functions are described above. The abdomen is also required for breathing via the accessory muscles of respiration.
