The earthworm has as its digestive system:
# a very primitive mouth. # a crop, a chamber where food can be ground up using the services of grains of sand and the like. It needs this as it doesn't have a mouth to do the job. # A stomach to digest food. # A REALLY long intestine. A straight hollow tube that is in-folded at the top - to give it a greater surface area to do its work on. (In cross-section think of it as a Capital letter 'O" with its top cut off and a lower-case 'u' inserted into the hole to block it) That as far as I got in the dissection. I assume that there is also an anus.
