/^\
/ \ etc.
Odontophore apparatus what is ment by this
the base of the radula
Why did the molluscan mdigut even evolve
the molluscan midguy evolved to process fine particles produced by the odontophore aparatus
Give the structure names of the molluscan midgut
Crop
Stomach
Hepatopancrease
intestine
give a generalized idea of where food goes starting from the foregut
forgut to the revovleing "style" which grinds the food down where it will either then go out to the intesitnes or ir will go to the hepatapancrease and then out to the intestines

How many stages are there to torsion
two
What are some advantages to torsion of the body
quicker retreat
better balance
How is breathing accomplished in molluscs
