THE
DIGESTIVE
SYSTEM
, These notes will help you demonstrate your ability to microscopically and macroscopic identify,
recognize, illustrate and label correctly the different tissue types of the digestive system. Please
remember that this is just a summary of the textbook. I will link the textbook and you can have a
look at it to get a more detailed explanation of everything
FUNCTIONS OF THE DIGESTIVE SYSTEM
•Ingestion—taking in food
•Digestion—breaking food down both physically and chemically
•Absorption—movement of nutrients into the bloodstream
•Defecation—rids the body of indigestible waste
ORGANS OF THE DIGESTIVE SYSTEM
•Two main groups of organs
•Alimentary canal (gastrointestinal tract)—continuous coiled hollow tube. These organs ingest,
digest, absorb, and defecate. The organs of the alimentary canal are:
Mouth
Pharynx
Oesophagus/Esophagus
Stomach
Small intestine
