Alimentary Canal of Earthworm
The alimentary canal is a straight tube that runs between the first segment to the last segment of the body of an earthworm.
The buccal cavity is situated in 1-3 segments.
It is followed by the muscular pharynx.
The pharynx is followed by an esophagus in 5-7 segments.
It is followed by a muscular gizzard in 8-9 segments.
The 9-14 segments contain the stomach.
The intestines are the major organs that begin from the 15th segment and continue until the last segment.
During digestion, the ingested soil is passed through the digestive tract and is digested into small absorbable substances which are absorbed through the membranes of the intestine.
