The most common similarity among the various Mollusca's digestive system would be the use of cilia. Cilium are short eyelashlike filament that are numerous on tissue cells of most animals especially the Mollusca animals. They are used for movement are are inside all the digestive tracts providing movement for various reasons. The digestive system is the part of the body which does this job. It stretches from the mouth to the anus and consists of a series of organs and glands which secrete digestive enzymes. These function in a coordinated manner to break down food – a process known as digestion - and convert the food we eat into a form that can be absorbed/10(7). Digestion, Absorption and Use of Food The alimentary canal is a tube, running through the body The alimentary canal is lined with epithelium cells There are also cells in the lining which produce mucus Mucus is a slimy liquid which lubricates the lining of the canal and protects it from wear and tear. It may. Activity | In this activity, students plan and build a walk-through model of the digestive system.. To get started, ask students to name the parts of the digestive system and to imagine how they could create a larger-than-life model to represent each section.. For example, students might divide their classroom into a twisting maze of different compartments, including the mouth, esophagus and.

Organs investigated include the mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus. The role of the digestive tract is to break down and absorb food to ensure: building, protection, and the smooth functioning of the body. This breaking down of food is carried out by the different organs of the digestive tract and its adjacent glands.
See the school curricula Download the lesson. Digestive System The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed body cells. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract).One of these systems is the digestive system.
The digestive system is made up of the digestive tract. This is represented by a hollow tube running from the mouth to the anus. Through this system, the body is able to break down and synthesize food consumed. Digestive system has a gastrointestinal tract and some associated glands.
In human gastrointestinal tract starts in mouth, leading to oral cavity. There are teeth on both the jaws, and a tongue inside oral cavity. Oral cavity leads to a common chamber for the passage of both air and food, called pharynx.
Food pipe or oesophagus open in pharynx and swallowed food can travel to stomach.
