it has nothing to do with sharks.
The five hearts and esophagus (which are on top of the central nervous cord)
First, after the mouth is the pharynx. Then the crop,(holds food) then the gizzard(crushes food) then the intestine, then lastly the anus. Hope this helped!
The food enters the pharynx, then through the esophagus, then acts as a passageway between the pharynx and the crop. Then it goes through the gizzard.
lol, are you doing sections 1 and 2 for mollusks and segmented worms?
Well, it's the stomach because the food we eat is temporarly stored. And that's what happens when an earthworm eats food, it's temporarly stored in the crop. So in other words the "stomach" is similair to the crop.
A pharynx in a worm is basically an organ that a worm uses to eat. It is thread-like I believe, and a worm pushes it out of their mouth, gets the food, and eats it. So I guess, it could be comparable to a tongue in a human.
the crop
The esophagus of an earthworm is part of the earthworm's digestive tract, between the pharynx and the crop, and it basically just moves the earthworm's food from the pharynx to the crop. It also helps to keep the food from backing up (making the worm barf/throw up).
The digestive system is partitioned into many regions, each with a certain function. The digestive system consists of the pharynx, the esophagus, the crop, the intestine and the gizzard. Food such as soil enters the earthworm's mouth where it is swallowed by the pharynx. Then the soil passes through the esophagus, which has calciferous glands that release calcium carbonate to rid the earthworm's body of excess calcium. After it passes through the esophagus, the food moves into the crop where it is stored and then eventually moves into the gizzard. The gizzard uses stones that the earthworm eats to grind the food completely. The food moves into the intestines as gland cells in the intestine release fluids to aid in the digestive process. The intestinal wall contains blood vessels where the digested food is absorbed and transported to the rest of the body.
Temporary storage occurs in the crop of an earthworm
to store the food
It stores food
