Two openings: Most efficient
If food flows only one direction it allows for organ specialization(Different parts can start to do different jobs)

Advantages of having a COELOM (body space):
In animals without a skeleton- Fluid in coelom space can act as a HYDROSTATIC skeleton
In animals without blood vessels- Fluid in coelom space can circulate nutrients and oxygen to cells
Provides space for internal organs

WHY is a COELOMATE the best?
Digestive organ muscles and body wall muscles come from MESODERM in different places so organism can digest food and move at same time.
