Digestion Basics

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

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

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

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

Stores bile mechanically breaks down fat particles for easier digestion

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

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

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

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)

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

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

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

Egestion is solid waste unable to be digested (so poop) Excretion is metabolic waste usually salts, water, urea (so pee)
