Flashcards in Ch 25 Lec 1 - Digestive System Deck (42):
0

process whereby food is changed into a form that can be absorbed

digestion

1

production of ATP by body process

metabolism

2

digestive tract is aka the blank and includes the mouth, pharynx, esophagus, stomach, intestines, rectum, anus

alimentary canal

3

food enters via mouth

ingestio

4

squashing, tearing, crushin, mixing, churning of food

mechanical processing

5

chemical and enzymatic breakdown

digestion

6

four layers of digestive tract

mucosa, submucosa, muscularis, serosa

7

inner most layer of digestive system with three layers

mucosa

8

three layers of mucosa

mucosal epithelium, lamina propria, muscularis mucosa

9

layer of mucosa that has blood vessels, sensory nerves, lymph vessels, and MALT

lamina propria

10

may have folds to increase surface area and may have glands layer of digestive system

mucosa

11

layer of digestive system including loose connective tissue, glands, blood vessels, lymph vessels, and nerves

submucosa

12

layer of digestive system with layers of visceral smooth muscle

muscularis

13

two layers of muscularis

inner (circular), outer (longitudinal)

14

serosa is aka blank

visceral peritoneum

15

serosa does not exist superior to diaphragm and there is blank instead

adventitia

16

serosa has blank and blank tissue

connective, epithelium

17

this propels bolus down the digestive tract

peristalsis

18

in peristalsis, blank muscles contract first which prevents bolus from moving back

circular muscles

19

no net movement in any particular direction and goal is to fragment bolus in this motor functino

segmentation

20

there is mostly blank muscle contractions in segmentation

circular

21

a series of membranes in the abdominal cavity

peritoneum

22

membrane of abdominal cavity that adheres directly to the internal organs

visceral

23

membrane of abdominal cavity that adheres to the abdominal wall

parietal

24

peritoneal membranes are blank with one another and there is a blank in between

continuous, cavity

25

sheets of peritoneum connected to organs and are an access route for vessels and nerves and stabilize position

mesenteries

26

connects the stomach to the liver

lesser omentum

27

this starts at the stomach descends inferior and then forms a pouch filled with adipose tissue that connects to the colon

greater omentum

28

part of peritoneum that attaches to the majority of the small intestine

mesentery proper

29

part of peritoneum that attaches to large intestine

mesocolon

30

mesentery proper and mesocolon both allow for nerves, blood vessels and lymphatics to connect to blank

intestines

31

lips are aka

labia

32

this is a part of the mouth that is everything enclosed by lips and cheeks

oral cavity

33

oral cavity is made of blank epithelium

stratified squamous

34

area of mouth between lips cheeks and teeth

vestibule

35

palatine bone on roof of mouth

hard palate

36

connective tissue extension of the palate

soft palate

37

this prevents food from going down prematurely

uvula

38

body of the tongue is made of blank muscle

skeletal

39

papillae of tongue house blank

taste buds

40

tongue part that is anchored to the hyoid

root

41

tongue part that is connected to floor of mouth

frenulum
