Well, first of all, there are your mouth and teeth, which help to chew the food and grind it up into small pieces. It then goes into your esophagus, down your throat, and passes into the stomach, where it is compressed into smaller pieces. Later, it is transferred into the small intestine, then the large intestine, and out. So, to answer your question, the main organs are the mouth/teeth, the esophagus, the stomach, and the large and small intestine.
The gastrointestinal tract is a long, continuous tube of varying diameter extending from the lips to the anus. It functions are to alter the food mechanically and chemically to a form which can be absorbed, to perform the processes of absorption, to form and secrete bile and digestive enzymes and, to eliminate the unabsorbed residue.
The detailed structure of each of the parts of the digestive tube is related to their specific functions, but the overall architectural plan, particularly from the esophagus to the recto-anal junction, is for the most part, the same.
The wall of the tube, particularly from the esophagus to the recto-anal junction, usually consists of four layers: the mucosa (or mucous membrane), the submucosa, the muscularis externa, and either a serosa or an adventita, depending on location.
Muscular tissues, epithelial tissues, and connective tissues.
I know that epithelial, connective, nervous, and muscle tissue make up the stomach. But other than that, I don't really know anything else.
Hope it helps!
Epithelium tissue and muscle tissue.
No, the digestive system is an organ system made up of organs, which in turn are made up of tissues.

Bones are tissues that make up skeletal system.
The human body is made of organs. Certain organs work together to form systems. We each have a respiratory and a Circulatory system, Digestive system and Excretory System.
Cell make up tissues,tissues make up organs and organs make up organ systems, and organ systems make a whole organism
Cells make up Tissues, Tissues make up organs, and organs make up body systems. (which i think you called an organ system)
Cells make up Tissues, Tissues make up organs, and organs make up body systems. (which i think you called an organ system)
the tissues in the skeletal system are *bones *cartilage *ligaments
Cell builds up the tissues and tissues make up organs and organs together make up a system so the only difference is that system lies in a bigger category.
i) glands; ii) organs; and iii) tissues -
yes
In a multicellular organism muscle cells make up smooth muscle tissue, then along with other tissues they make up the stomach or an organ. Therefore, the stomach is part of an organ system, the digestive system.
