unit c - digestive system

Question 1

pancreatic lipase

Answer 1

produced in the pancreas
found in the galbladder
active in the duodeum
-helps the body break down the fats in food, so the intestines can absorb them

Question 2

pancreatic amylase

Answer 2

produced and stored in the pancreas
active in the stomach
-helps break down carbohydrates and startches

Question 3

trypsin

Answer 3

produced in the pancreas
stored and active in the small intestine
-helps digest proteins

Question 4

hydrochloric acid

Answer 4

produced, stored and active in the stomach, by small glands
-part of your stomach acid, breaks down the food in stomach
digestive enzymes split up proteins

Question 5

amylase

Answer 5

produced in the salivary glands
moved by the pancreas to be stored in the small intestine
-breaks bonds in startches, polysaccharides and compact carbohydrates to transform them into absorbable sugars

Question 6

disaccharidase

Answer 6

prodcued and stored in the walls of the small intestine
active in the large and small intestine
-breaks down complex sugars into simple sugars

Question 7

bile

Answer 7

EMULSIFIER
produced in the liver
stored in the gallbladder
active in the stomach
-breaks down large pieces of fats so they have more surface area to continue being broken down (for lipase to function)`

Question 8

pepsin

Answer 8

produced in the stomach cells, in pepsinogen form
transformed into pepsin in the stomach acid
active in the stomach
-breaks down proteins into smaller polypeptides

Question 9

pepsinogen

Answer 9

the form of pepsin in our stomach cells, that is transformed just when our body needs it
-pepsinogen would eventually start eating ourselves alive

Question 10

mucus

Answer 10

SECRETION
produced in the gasteral track, mouth and nose
stored in nose and throat
active in mouth, lungs, stomach
acts as a protectant and moisturizing layer to keep organs from drying out

Question 11

erepsins

Answer 11

produced in the small intestine and pancreas
stored in protein fractions
active within the final section of the small intestine
breaks bonds between proteins releasing individual amino acids

Question 12

appendix

Answer 12

is a thin tube attached to the large intestine

-helps with childrens immune system

Question 13

pharynx

Answer 13

part of the the throat behind the mouth and nasal cavity

-tubes going down to the stomach and lungs

Question 14

epiglottis

Answer 14

Question 15

esophagus

Answer 15

muscular tube connecting the throat with the stomach

Question 16

hormones

Answer 16

chemicals released by cells in one part of the body, that affect other cells

Question 17

gastric juices

Answer 17

HCL, pepsin and lipase mixture found in the stomach lining, it is meant to kill microorganisms swallowed and protect the body

Question 18

stomach

Answer 18

muscular organ used to store food from the esophagus

-holds acid and enzymes to break down food

Question 19

lower esophogal sphincter

Answer 19

where food enters the stomach, it is a muscular valve

Question 20

duodenum

Answer 20

the first part of the small intestine, begins the intake of nutrients

Question 21

esophagus

Answer 21

long tube, that is contracting (undulating) as it swallows the food

Question 22

lacteal

Answer 22

part of the lymphatic system, found in the villi that transports the products of fat digestion to the circulatory system

Question 23

prosecretin

Answer 23

precursor to secretin, which is present in digestion

Question 24

secretin

Answer 24

hormone released from the duoduem that stimulates pancreatic and bile secretions

Question 25

HCO3

Answer 25

product of the bodys metabolism, regulates the bodys pH or acid balance

Question 26

Enteropeptidase (enterokinase)

Answer 26

enzymes produced by the duodenum, that converts trypinsogen to trypsin

Question 27

trypinsogen

Answer 27

produced in the pancreas, precursor to trypsin

Question 28

trypsin

Answer 28

protein digesting enzyme

Question 29

erepsins

Answer 29

an enzyme that completes protein digestion by converting short-chain peptides to amino acids

Question 30

pancreas

Answer 30

digests food, and manages your use for sugar for energy after digestion

Question 31

liver

Answer 31

creates bile and detoxifies many substances in the body

Question 32

Answer 32

aids in fat digestion

Question 33
