Digestive System Part 2

Front 1

3 Parts of the Small Intestine

Back 1

Duodenum
Jejunum
Ileum

Front 2

Duodenum

Back 2

about 30cm this is where the chyme is buffered and where the pancreatic enzymes and bile are added to the chyme

Front 3

Jejunum

Back 3

2 1/2meters or 9ft. long. This is where the absorbtion of everything but water takes place

Front 4

Ileum

Back 4

3meters This is the finishing of the absorption that didnt happen in the Jejunum

Front 5

Surface Area of small intestine

Back 5

3300cm2, because it has folds and villi it has over 2million cm2 or (2200ft2)

Front 6

Villi contain...

Back 6

lacteals

Front 7

lacteals

Back 7

specialized lymphatic capillaries, molecules that are too big are moved out of chyme and moved to the lacteals-fats and lipids

Front 8

Pancreas

Back 8

only organ that has endocrine and exocrine functions, secretes hormones into the interstitial spaces, insulin, somatasion, glucagon which regulates blood sugar

Front 9

pancreas enzymes

Back 9

protease-breakdown proteins
Lipase-breakdown lipids
carbohydrase- breakdown carbs

Front 10

Liver

Back 10

over 200 vital functions, breakdown of categories
1.metabolic regulation-excracting absorbed nutrients and/or toxins from blood processing to be readily used or excreted
2.hematologic regulation-synthesizes blood proteins, especially albumins
3.bile production-synthesizes and creates bile
Funtional unit is the lobule, which is able to replace itself

Front 11

Lobules

Back 11

made up of sinusoids and hepaticites

Front 12

Bile

Back 12

mixture of water, ions and bile salts the water and ions are used to buffer the chyme, bile salts are synthesized from chloesterol for normal digestion of fats

Front 13

Gallbladder

Back 13

1.Bile storage
2.Bile modification

Front 14

Emulsify

Back 14

you can cover a droplet of non-polar molecules with bile salts (which are part polar and part non-polar) when surrounding the droplets they then can dissolve into water

Front 15

Large Intestine

Back 15

colon function-dehydrate the chyme-most water absorption occurs here, it recieves the chyme through the ileocecal valve which controls the chyme to the cecum

Front 16

Cecum

Back 16

veriform appendix

Front 17

The large intestine colons

Back 17

Ascending Colon-right side, spends a lot of time here because of gravity, most water absorption occurs here
Transverse Colon-across
Descending Colon-downwars
Sigmoid Colon-leads to rectum

Front 18

Colorectal Cancer

Back 18

extremely high death rate unless caught early

Front 19

Feces

Back 19

75% water 5%bacteria 20% indigestible materials and inorganic type stuff
