The small intestine, specifically the jejunum is where most of the absorption occur.
Buccal Cavity
The alimentary canal performs all the functions of preparing eaten food for absorption into your body, Without it, their would be no digestive system or digestion. Life would not be possible.
Digestive
The part of the digestive canal involved in the formation of feces is the large intestine, also known as the colon. In the large intestine, water and electrolytes are absorbed from the undigested food material, leading to the formation and compaction of feces. The remaining waste is then stored in the rectum until it is expelled from the body through the anus.
Digestive organs and the system in general can be divided into two parts: the accessory organs and the alimentary canal. The alimentary canal is the GI tract and the accessory organs are things like the teeth, tongue, salivary glands, and gallbladder.
A tube shaped compartment for the transfer, digestion, and absorption of food. Solid waste is expelled from it too. It extends from mouth to anus. It includes all digestive system and pathway of food you eat. Hope this helps!
Peristalsis is the involuntary muscle action of the alimentary canal. It involves wave-like contractions that push food along the digestive tract, allowing for the process of digestion and absorption to occur.
The digestive tube structure in both earthworms and grasshoppers consists of several folds. These folds affect the efficiency of food absorption by increasing the surface area.
The muscular contractions move the food, mix it with digestive juices, and bring the digesting food in contact with the mucosa where absorption takes place.
it is the Digestive Tract - food in one end, waste out of the other
The digestive system of a cockroach consists of a long alimentary canal that runs from the mouth to the anus. It includes structures such as the crop for storing food, the gizzard for grinding food, and the midgut for digestion and absorption of nutrients. Waste materials are eliminated through the anus.
The involuntary motion that moves food through the alimentary canal is called peristalsis and is a wavelike contraction and relaxation of the intestinal wall smooth muscles. It pushes food along the intestine.
