Study Notes
Insect Digestive System
- Foregut consists of the proventriculus, which may be armed with spines or teeth.
- Midgut consists of the main region for enzymatic digestion and nutrient absorption.
Excretory System
- Malpighian tubules are the main excretory organs of the insect body.
- The number of Malpighian tubules varies, and they enter the alimentary canal at the junction of the midgut and hindgut.
- The excretory system maintains a constant internal environment by regulating water and ion balance.
- The choice of nitrogenous excretory product depends on the need to conserve water.
- The selection of a given product as a nitrogen excretory molecule results from a tradeoff between the toxicity of the compound and the energy required for its synthesis.
