Alimentary Canal - Digestive - Pathophysiology Cs

Front 1

main part of digestive system

Back 1

alimentary canal

Front 2

GI Tract =

Back 2

alimentary canal

Front 3

gastrointestinal tract =

Back 3

GI tract

Front 4

tube that extends from lips to anus; is coild, varies in diameter, and parts are identified individually; is never branches; is a single continuous tube; approximateloy 9 meters (30 feet long); made up of 4 layers or tunica (coat or covering)

Back 4

alimentary canal

Front 5

coat or covering

Back 5

tunica

Front 6

4 alimentary canal layers

Back 6

tunica serosa, tunica muscularis (inner and outer), tunica submucosa, tunica mucosa

Front 7

tunica serosa =

Back 7

tunica adventitia

Front 8

covers all vital organs

Back 8

visceral peritoneum

Front 9

n the abdominal cavity, the serosa on each side of the lumen (tube) fuses together to form a suspensory structure

Back 9

mesentery

Front 10

inner and outer layer gives the alimentary canal ability to be motile (having ability of spontaneous movement).

Back 10

tunica muscularis

Front 11

ability to perform complex movements that squeeze and propel solid or liquid nutrients in the lumen

Back 11

peristalsis

Front 12

between the inner circular and outer longitudinal layers of smooth muscle; critical component of digestive tract's nervous system

Back 12

myentric plexus

Front 13

lies between the mucosal and inner muscularis layers; is highly vascular (containing many blood vessels); composed of elastic and collagen fibers, and its function is to serve the mucosal layer; also contains the submucous plexus, a critical component of the digestive tract’s nervous system that provides nervous control to the mucosa

Back 13

tunica submucosa

Front 14

innermost layer of alimentary canal; lines the digestive tract; most widely varies of the 4 tunic layers; allow the lumen (tube) the ability to perform digestive tasks along its length; within are epithelium cells vital to the functions of absorption and more

Back 14

tunica mucosa

Front 15

located beneath the epithelium, but still within the tunica mucosa; is loose connective tissue; blood vessels and lymphatics course through the lamina propria to supply the epithelium. Beneath the lamina propria is the lamina muscularis mucosae, a thin layer of smooth muscle that allows the mucosa to move and fold.

Back 15

lamina propria

Front 16

3 tunica mucosa functions

Back 16

distention, absorption, secretion

Front 17

state of being enlarged or allowing for an increased capacity; occurs most in stomach

Back 17

distention

Front 18

process of of absorbing or assimilating nutrients, such as in the small intestine, or the absorption of water in the colon.
secretion *alimpathdig - where glandular parts secrete digestive enzymes into the cavity to break down food, such as in the stomach.

Back 18

absorption

Front 19

single layer of skin cells that lines body cavity within the peritoneal cavity

Back 19

mesothelium

Front 20

double layer of peritoneum that attaches various organs to the body wall

Back 20

mesentery

Front 21

2 omentum sections

Back 21

lesser omentum and greater omentum

Front 22

extends from the lesser curvature of the stomach to the underside of the liver

Back 22

lesser omentum

Front 23

extends from the greater curvature of the stomach to the transverse colon

Back 23

greater omentum

Front 24

some abdominal organs positioned outside the coelomic cavity that are not not covered by peritoneum: pancreas, kidneys, most of duodenum, and abdominal aorta

Back 24

retroperitoneal

Front 25

organs that release enzymes to break down food

Back 25

secretory organs

Front 26

double folds of peritoneum supporting the viscera

Back 26

omentum
