The five hearts and esophagus (which are on top of the central nervous cord)
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).
Temporary storage occurs in the crop of an earthworm
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.
In earthworms you have two pair of Ganglia, one pair under the pharynx and another above, the ganglia above the pharynx serves as the brain, the ventral nerve cord connects all organs in the earthworms.Please see related link below!
Earthworms do not have jaws. They suck their nutrition through their mouth by the help on the pharynx and this food is churned in the gizzard after passing trough the esophagus and or being stored in the crop.
it has nothing to do with sharks.
Yes, the esophagus of an earthworm lies beneath the pharynx. The esophagus is the part of the digestive system that connects the pharynx to the crop, where the initial stages of digestion take place in an earthworm.
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.
In a cross section anterior to the gizzard of an earthworm, you would find the crop, esophagus, pharynx, and the mouth. The crop stores food temporarily before it moves to the gizzard for further mechanical digestion.
Yes, in an earthworm, the esophagus lies beneath the pharynx. The pharynx is responsible for the intake of food, and the esophagus then transports it to the crop for storage. This arrangement allows for efficient processing and movement of food through the digestive system.

lol, are you doing sections 1 and 2 for mollusks and segmented worms?
lol, are you doing sections 1 and 2 for mollusks and segmented worms?
it swallows the food
The segment number of the pharynx on an earthworm is around 4-7. Hope that helps.
with the help of pharynx
