Organs having different functions in digestion, food absorption and waste elimination

Rectum, where the undigested food is absorbed

Organs responsible for the digestion and subsequently the elimination of food

Several parts: mouth, pharynx, oesophagus, stomach, small bowel, large bowel

Glands: salivary, liver, pancreas

The laryngopharynx

The lingual frenulum

The teeth

The nasopharynx

The tongue

Carries out multiple roles

Acts as a sensory organ

Is located in the oropharynx

Contains taste papillae (filiform, calyciform, fungiform and foliate)

Is also a digestive organ

Is delimited superiorly by the hard palate

Is a segment of the digestive tract

Contains a cavity

It is part of both the digestive and the respiratory systems

Communicates in its upper part with the oral cavity

All the above

Communicates with the stomach through the cardia

Is located between the pharynx and the stomach

Conducts the bolus towards the pharynx

Is a segment of the pharynx

Has an upper opening, the pylorus, through which it communicates with the oesophagus

Is a dilated part of the digestive tract

Secretes approximately 3-4 L of gastric secretions/day

Is located in the abdominal cavity

Has an inferior opening, cardia, through which it communicates with the duodenum

C. In the duodenal mucosa, it contains Brünner’s glands

A. Is the segment of the digestive tract between the stomach and the colon

D. In the duodenum, it contains the opening of the cystic canal

B. Extends between the stomach and the caecum

E. Has three segments: duodenum, jejunum-ileum and caecum

Contains the openings of the choledoch and of the main pancreatic ducts

Is the first segment of the small bowel

Extends from the pyloric sphincter to the left colic flexure

Is located between the stomach and the ileum

Is a C-shaped structure which envelops the tail of the pancreas

Have a small surface area

Contain an arteriole and a venule

Their base contain intestinal crypts

Present a surface pavimentous epithelium whose cells contain secretory cells

Are specialised structures of the small bowel mucosa

Is located in the abdominal and pelvic cavities

Is subdivided into caecum, vermiform appendix and colon

Ends with the anal canal

Is a continuation of the duodenum

Has three segments

Produces no digestive enzymes

Is a continuation of the caecum

Is continuous with the rectum

Has several segments

Is a part of the small bowel

Is the terminal part of the large bowel

Its walls contain smooth muscle fibres

Is a continuation of the descending colon

Ends with the anal canal

Is a subdivision of the colon

Salivary glands

Liver

Endocrine pancreas

Pyloric glands

Brünner’s glands

Are involved in oral digestion

Secrete saliva

Consist of the submandibular, sublingual and parathyroid glands

Secrete their products into the oral cavity

Are innervated by the somatic nervous system

Is projected in the right hypochondrium and the epigastrium

Lies to the right of the stomach

Is delimited inferiorly by the diaphragm

Is the largest accessory digestive gland

Is located on the right side of the body, above the diaphragm
