ANATOMY AND PHYSIOLOGY OF DIGESTION
DIGESTIVE SYSTEM
2 main groups:
1) Alimentary canal (lumen, stomach and intestinal system)
Gastrointestinal tract
Continuous digestive tube through whole body
Function:
A) Digestion
breaks food into smaller fragments
B) Absorption
moves the digested fragments from the alimentary canal into the blood
Consuming cooked egg is better than uncooked, helps the digestive system by cooking
To get nutrients out of lumen to cardiovascular system, we move it into blood
Anatomical structures
Mouth (lips, cheeks, palate, tongue, teeth, salivary glands) – start digestion
Pharynx
Esophagus – cardiac orifice is the opening from esophagus to stomach

Stomach (cardiac orifice, fundus, body, pyloric canal, pylorus, pyloric sphincter, omentum)
Small intestine (duodenum (shortest), jejunum, ileum) – very long tube (the major
absorptive system)
Large intestine (cecum, ascending colon, transverse colon, descending colon, sigmoid colon,
rectum, anal canal)
considered to be “outside” the body (still in external environment)food that has not been
absorbed
2) Accessory digestive organs (outside the Alimentary canal that secret chemicals)
teeth, tongue, gallbladder, liver, pancreas
