and the pharynx is the tubing that leads down the throat and to the digestive track (esophagus). I may have missed something, but I don't think the worm has anything that really resembles this. I believe the pharynx is a pressure duct and systematically makes sure the food is coted in saliva and other aids as it starts its trek downwards (or upwards if you live in Australia??)

In Bio2 we had to dissect three baby fetal pigs. I chose an IT profession after that.
