<h2>Anterior-posterior orientation</h2>
Explanation:
Flatworms have an anterior-posterior orientation and as a result more coordinated and deliberate movement is established
- Flatworms also called Platyhelminthes are a phylum of relatively simple soft-bodied invertebrate animals
- They are the largest phylum of acoelomates and are found in marine,freshwater and even in some damp terrestrial environments

- Flatworms anterior end helps in moving towards their food while the posterior end ensures that these organisms walk away from irritants
The given blank can be filled with the production of endorphins.
The endorphins are the hormones, which are responsible for the activation of the opiate receptors in the body. They are the natural pain killers. The activation of the opiate receptors causes the analgesic effects on the body.
These endorphins are secreted in the brain and the nervous system. The effect of the endorphins is similar to that of the morphine.
