Uvula
passageway for food from the mouth to the esophagus
Oropharynx and Laryngopharynx
passageway for food to the stomach
Esophagus
prevents reflux of stomach acid
Gastroesophageal (inferior esophageal)
mixes food with HCl and digestive enzymes to form chyme
stomach
controls the entry of cyme into the duodenum
Pyloric Sphincter
secures the stomach to the abdominal wall and to other organs
Greater Omentum
completes chemical digestion; absorption of food molecules
Small intestines
slow movement of chyme through the small intestine to increase time for absorption
circular folds
absorb food molecules and allow them to enter a blood capillary or lacteal
Villi
controls entry of waste into the large intestine
ileocecal
three bands of smooth muscle that pucker the large intestine creating haustra
Teniae coli
contract slowly to allow time for water absorption and to move waste to the next haustrum
Haustra
fights infection
Vermiform appendix
secures the small intestines
Mesentery
produces bile, detoxifies blood, stores glycogen and fat-soluble vitamins
Liver
attaches the liver to the diaphragm and abdominal wall
Falciform ligament
