The insect abdomen primarily performs which functions?

• A. Functions in digestion and reproduction
• B. Supports wings and legs
• C. Involved in vision and balance
• D. Stores digestive enzymes

Answer: (A)

The abdomen’s main job is hosting the digestive system and the reproductive organs. Digestion mostly happens along the gut housed there, with absorption and waste management taking place in the posterior sections, and the ovaries or testes are located in the abdomen as well, making reproduction another primary function. The wings and legs are attached to the thorax, not the abdomen, so supporting them isn’t an abdominal role. Vision and balance are governed by head structures (and some thoracic organs used for balance), not the abdomen. Digestive enzymes are produced along the digestive tract, not stored as a primary function of the abdomen. So digestion and reproduction are the best-fit description.
