Answer 2

digestion and absorption

Question 3

length small instetsine

Answer 3

4,5 m

Question 4

how is the small intestine seperated and fct

Answer 4

duodenum receives chyme, pancrratic digestive enzyme and bile from liver, jejunum-ileum

Question 5

function of villi and microvilli (brush border)

Answer 5

produce enzymes for digestion and absorbtion

Question 6

function large intestine

Answer 6

water reabsobtion, waste material accumulation

Question 7

size large intestine

Answer 7

1,5 to 1,8 m

Question 8

Answer 8

cecum, colon (ascending, transverse, descending), rectum (includes anal canal)

Question 9

liver

Answer 9

secretes bile pigments and salts, detoxifies

Question 10

bile salts

Answer 10

prepare fat for enzymatic digetsion

Question 11

where is bile stores

Answer 11

gallbladder

Question 12

Pancreas type of gland and what it secretes

Answer 12

secretes pancreatic juice (trypsin, chemotrypsin, pancreatic amylase, lipase)

large exocrine and endocrine gland

Question 13

whtàat type of enzymes are digestive enzymes and where do they operate

Answer 13

extracellular enzymes operation in lumen of digestive tract

Question 14

carbohydrate digestion and enzymes

Answer 14

• polysaccharides hydrolyzed to dissacharides by salivary amylase and pancreatic amylase
• dissacharides hydrolyzed to monosaccharides by sucrase, lactase, maltase in brush border

Question 15

protein digestion

Answer 15

proteases hydrolyze proteins to aa

Question 16

proteases (for protein digetsion) example

Answer 16

pepsin, trypsin/chymotrypsin, peptidase

Question 17

lipid digestion

Answer 17

• bile salts emulsify fats in lumen small intetsine

- lecithin emulsify fats by creating micelle combining with chylomicrons entering lymphatic system

Question 18

Nucleic acid digestion

Answer 18

• pancreatic nucleases produces nucleotides

- nucleotidase in brush border breaks down into nitrogenous base, sugar, phosphate

Question 19

name all digetsive enzymes and location

Answer 19

Amylase (salivary glands)
pepsin (stomach)
Lipase (pancreas)
Trypsin (pancreas)
Chymotripsin (pancreas)
Peptidase (small intestine)
Nucleases (SI)
Lactase, maltase, sucrase (SI)
