1

The process of taking food into the digestive tract, typically occurs at the mouth

Ingestion

2

Process that moves food through the alimentary canal.

Propulsion

3

Pattern of smooth muscle activity that pushes material through the lumen of an alimentary organ and into another

Peristalsis

4

Break larges pieces of food into pieces or makes large molecules spread or break up, thus increasing the amount of surface area of that food/molecule that is exposed to

Mechanical breakdown

5

Chewing, mixing food with saliva by tongue and teeth, churning of food in the stomach, and emulsification

Mechanical breakdown

6

Process that uses enzymes to catalyze catabolic chemical reaction

Digesion

7

Process that involves the movement of organic monomers from the lumen of the GI tract and into the blood or lymph

Absorption

8

Muscular process that elminates undigested/indigested material from the body in the form of feces, typically occurs at the anal opening

Defecation

9

Organs suspended by mesinteries within the abdominopelvic cavity

Intrapertioneal orangs

10

Abdominopelvic organs that lack mesentery and which are embedded in the posterior abdominal wall

Retroperitoneal organs

11

Moist epithelial membrane that faces the lumen and interacts with its contents. extends from the mouth to the anus

Mucosa

12

layer of areolar CT deep to the muscosa, contains a rich supply of blood and lymphatic vessels. lymphoid follicles and nerves that support the muscoa

Submucosa

13

layer of composed of at least 2 layers of smooth muscles that is deep to the submucosa. produces movements associated with segmentation

muscularis externa

14

Layer that faces the abdominopelvic cavity, compoused of areloar CT covered with simple squamous epithelium

Serosa

15

fibrous Ct layer that covers the external surface of digestive organs that are not in the abdominopelvic cavity, I.E. the esophogas

adventitia

16

Set of systemic arteries that deliver oxygen rich blood to the abdominopelvic digestive organs

Splanchnic circulation

17

All three of these unpaired arteries that branch from the anterior surface of the abdominal aorta

Celicia trunk, superior mesenteric arety, and the inferior mesentaric artery

18

Set of veins that make up the hepatic portal circulation

consists of veins that collect the blood draining away from the abdominopelvic digestive organs

19

Once the liver has removed cetrain nutrients for use and or storage, the blood is directed into hepatic veins

these veins then direct oxygen poor, nutrient poor blood into the inferior vena cava so it can be returned to the heart

20

Once the liver has removed cetrain nutrients for use and or storage, the blood is directed into hepatic veins

these veins then direct oxygen poor, nutrient poor blood into the inferior vena cava so it can be returned to the heart

21

Site of ingestion, lined with oral mucosa containing non-keritinated stratified squamous epithelium to withstand friction, continuous posteriorly with the oropharynx

Mouth AKA oral cavity

22

Forms the roof of the mouth

palate

23

Anterior part of the palate, composed of bone and forms a firm surface against which the tongue forces food during chewing

hard palate

24

Posterior part of the palate which is composed of skeletal muscle, contacts to black the nasopharynx

soft palate

25

structure composed of multi-directional bundles of skeletal muscle that occupies the floor of the oral cavity, it reposititions the good between the food and teeth during chewing and hels mix the food with saliva to create a food/salvia mass

Tongue

26

Mass of food and salvia

bolus

27

Located on the surface of the tounge, taste buds

papillae

28

paired sets of exocrine glands connected to the oral cavity by ducts - secrete saliva

salivary glands

29

An acidic fluid rich in electrolyes and chemicals associated with innate immunity, Its main function is to begin the chemical breakdown of starchy foods by the enzyme salivary amylase

saliva

30

An acidic fluid rich in electrolyes and chemicals associated with innate immunity, Its main function is to begin the chemical breakdown of starchy foods by the enzyme salivary amylase

saliva
