appendix

I

rectum

J

sigmoid colon

K

descending colon

L

pancreas

M

stomach

N

parotid gland

O

anus

P

cecum

this structure hangs off the cecum and contains helpful bacteria

appendix

this muscular tube squeezes food from the throat to the stomach

 

esophagus           

this portion of the small intestine receives bile and pancreatic juices for chemical digestion

duodenum           

chemical digestion finishes here and most of absorption takes place in these structures

 

 jejunum & ileum           

this organ solidifies feces by absorbing water

 

 large intestine           

this organ produces bile and stores lots of nutrients such as glycogen           

liver

fecal matter is stored here until defecation

rectum           

these glands moisten food and release enzymes to start chemical digestion

 

              

 salivary glands

this structure mixes food with acid and other secretions to create chyme

stomach           

this structure produces insulin and glucagon, as well as digestive enzymes and bicarbonate

C

circular muscle

D

longitudinal muscle

E

F

lymphoid nodule

G

villus

H

brush border cell

I

blood capillary

J

lacteal

this blood vessel absorbs nutrients, vitamins and minerals

 

capillary           

this circular band of smooth muscle pushes food forward

 

circular muscle layer           

this structure absorbs fats bound to chylomicrons

lacteal

this longitudinal smooth muscle contracts in front of food to open the tube

 

longitudinal muscle layer           

this lymphatic tissue monitors the intestines for pathogens

 

 lymphoid nodule           

this innermost layer is next to the lumen and is made of epithelium

 

mucosa layer           

this outermost layer is the visceral peritoneum

 

serosa layer           

this layer is underneath the mucosa and contains blood vessels and nerves

 

submucosa layer           

these projections are covered with brush border cells

villus

A

hepatic portal vein

B

superior mesenteric vein

C

inferior mesenteric vein

D

splenic vein

E

gastric veins

F

inferior vena cava

the most common type of IBD that affects the large intestine and/or rectum, usually continuous inflammation of one region

 

                       

 ulcerative colitis

can affect any part of the GI tract, but commonly affects the ilieum and first portion of the large intestine, often spread out in patches

 

    

 Crohn's disease           

autoimmune condition caused by a gluten allergy, typically resolves when gluten is removed from the diet

 

celiac's disease
