diaphram

Answer 1

thin layer of muscle separates thoracic cavity from abdominal cavity

Question 2

heart

Answer 2

in the theoretic cavity has the artia at the top( two dark colored chambers, bottom chambers are the ventricles,

Question 3

liver

Answer 3

large dark, colored organ under the diaphram, produces bile that is stored in the gall blader to help digest fat, stores glycogen and transforms waste into less harmful substancces

Question 4

esophagus

Answer 4

runs through diaphram and moves food fro the moth to the stomach

Question 5

stomach

Answer 5

right side, under the liver functions food storage, physical breakdown of food, digestion of protien
the outer margin of the curved stomach is clled the greater curvature, th inner margin is called the less curvature

Question 6

spleen

Answer 6

same color as liver, attatch attatched t the greater curvature of the stomach looks like a banana functions: destruction of blood cells and blood storage you can liv wothout one but you’ll get sick more often

Question 7

cardiac sphincter

Answer 7

the opeinign of the stomach and esophagus

Question 8

pancreas

Answer 8

produces digestive enzymes that are sent to the intestine via small ducts it also secretes insulin

Question 9

small intestine

Answer 9

slender coiled tube that recieves paartialy digested food from the stomach it leads to the cecum

Question 10

cecum

Answer 10

pouch that connects the small and large intestines food is partially stored in the cecum while helpful bacteria digest the cellulose found in plant cells also called the appendix in humans

Question 11

Question 12

rectum

Answer 12

temporarily stores feces

Question 13

Pancreatic amylase

Answer 13

Source the Pancreas

Optimal pH 7.5-7.8

Substrate is starch (amylose)

End product is the disaccharide maltose

Action: hydrolysis of 1-4 glycosidic bonds

Question 14

Pepsin is a protease produced in the stomach

Answer 14

Source is the stomach

Optimal pH is 2

Substrate is a polypeptide chains of amino acids

End product is small polypeptides

Action is the hydrolysis of peptide bonds within the polypeptide chain (endopeptidase).

Question 15

Pancreatic lipases:

Answer 15

Source is the pancreas

The optimal pH is 7.2

The substrate is a triglyceride lipid

The product is glycerol and fatty acid chains

The action of pancreatic amylases also requires the presence of bile salts that emulsify the lipid. This emulsification has two effects:

Increases the surface area of the lipid for the digestion of fat

Exposes the glycerol ‘head’ structure to the enzyme

Action: hydrolysis of ester bonds between the glycerol molecules and the fatty acid chains.
