Digestion Basics

Question 1

Role of digestive system

Answer 1

Digestive system breaks the food down we eat into smaller molecules (monomers) that are readily useable at the cellular level.

Question 2

Order of GI tract

Answer 2

Mouth pharynx esophagus stomach small intestine large intestine rectum and anus

GI includes anything that food particles actively pass through

Mnemonic idea
Mushy= mouth
Poor= pharynx
Einstein= esophageal
Skipped= stomach
Sadly= small
If= Intestine
Lame= large
Iguanas= intestine
Returned= rectum
Arrongantly=anus

Question 3

Role of salivary glands

Answer 3

Food is mixed with saliva from salivary glands saliva contains an enzyme called salivary amylase that chemical digests starch turning some of it to maltose. Saliva also lubricates the food so it passes easier through the esophagus. Also helps create the bolus

Question 4

Pancreas role

Answer 4

Releases many enzymes to breakdown and digest the 4 macromolecules and also has a role in neutralizing HCL (hydrocloric acid).

Question 5

Gall bladdee role

Answer 5

Stores bile mechanically breaks down fat particles for easier digestion

Question 6

Liver role

Answer 6

Liver makes bile synthesizes HDL cholesterol amino acid and vitamins breakdown and covert nutrient store glycogen and fat and detoxify drugs alcohol and other poisons

Question 7

Ingestion process

Answer 7

The process of obtaining and eating and drinking food this included meds and poisons

Question 8

Digestion process

Answer 8

Includes two types of digestion to help turn the food into usable form has monomers

Question 9

Absorption process

Answer 9

The process of absorbing the monomers and passing them on to the bloodstream for distribution( circulatory takes these nutrients from the digestive system and deliver to cells of body)

Question 10

Elimination

Answer 10

Material that cannot be absorbed or digested must be eliminated from the body aka elimination and egestion

Question 11

Mechanical digestion

Answer 11

Grinding and mashing of the food to allow Surface area for chemical digestion

Question 12

Chemical digestion

Answer 12

Breaking down macromolecules by enzymes and hydrolysis into their monomers and subunits so they can be absorbed into the blood

Question 13

Difference between egestion and excretion

Answer 13

Egestion is solid waste unable to be digested (so poop)

Excretion is metabolic waste usually salts, water, urea (so pee)
