Earthworms have mouths; they can even open them wide enough to fit leaves and other good things. But they don't have teeth! Here is what happens to their lunch.
Pharynx: they push their pharynx or throat out of their mouths to grab leaves and to pull them back into their mouths. Then they get them wet with their .
Saliva. .
Esophagus: Once they have their food good and wet, they push it down their .
Esophagus, then onto their crop. .
Crop: their crop is a storage compartment for their food and other things they.
Swallow. From the crop, their lunch goppes to their gizzard. .
Gizzard: the gizzard is where the work happens. They use any stones that they have swallowed and the strong muscles of their gizzard to grind up the leaves. These muscles work almost like teeth. .
Intestine: Once they have the leaves all ground up they move to the intestine where the digestive juices break them down even more. .
Bloodstream: Now that the leaf is all digested, some of it will pass into the.
bloodstream. .
Anus: Whatever is leftover comes out their anus as castings or worm poop.
