2

the chemical breakdown of ingested materials into simple molecules that can be absorbed by the cells of the digestive tract

digestion

3

the active or passive uptake of gases, fluids, nutrients, or solutes

absorption

4

elimination from the body

excretion

5

a mucous membrane; the epithelium and the lamina propria

mucosa

6

layer of smooth muscle beneath the lamina propria; responsible for moving the mucosal surface

muscularis mucosae

7

region between the muscularis mucosae and the muscularis externa

submucosa

8

concentric layer of smooth muscle responsible for peristalsis

muscularis externa

9

parasympathetic motor neurons and sympathetic post ganglionic fibers located between the circular an ongitudinal layers of the musularis externa

myentric plexus

10

a double layer of serous membrane that supports and stabilizes the position of an organ in the abdominopelvic cavity and provides a route for the associated blood vessels, nerves, and lymphatics

mesentery

11

superficial layer of connective tissue surrounding an internal organ; fibers are continuous with those of surrounding tissues, providing support and stabilization

adventitia

12

a wave of smooth muscle contractions that propels materials along the axis of a tube such as the digestive tract, ureters, or the ductus deferens

peristalsis

13

pertaining to the cheeks

buccal

lip, majora and minora are componenets of the female external genitalia

labium/labia

15

the bony roof of the oral cavity, formed by the maxillary and palatine bones

fleshy posterior extension of the hard palate, separating the nasopharynx from the oral cavity

soft palate

17

an epithelial fold that attaches the inferior surface of the tongue to the floor of the mouth

lingual frenulum

18

an enzyme present in some exocrine secretions that has antibiotic properties

lysozyme

19

chewing

mastication

20

crystalline material similar in mineral composition to bone, but harder and without osteocytes, that covers the exposed surfaces of the teeth

enamel

21

bonelike material that forms the body of a tooth; unlike bone, it lacks osteocytes and osteons

dentin

22

internal chamber in a tooth, containing blood vessels, lymphatics, nerves, and the cells that maintain the dentin

pulp cavity

23

a premolar tooth

bicuspid

24

bicuspids; teeth with flattened surfaces located anterior to the molar teeth

premolars

25

the throat; a muscular passageway shared by the digestive and respiratory tracts

pharynx

26

a muscular tube that connects the pharynx to the stomach

esophagus

27

swallowing

deglutition

28

a compact mass; usually refers to compacted ingested material on its way to the stomach

bolus

29

a semifluid mixture of ingested food and digestive secretions that is in the stomach and proximal small intestine as digestion proceeds

chyme

30

the area of the stomach surrounding its connection with the esophagus

cardia
