Anatomy Exam 4
1.What part does the digestive system play in getting the body’s cells what they need for cellular
respiration?
The digestive system breaks down food into simpler molecules like glucose ,
which are absorbed into the bloodstream and
transported to cells , where they are used in cellular respiration to produce Alp for energy.
2. What is the interface of the gut with the external environment anatomically speaking? {No,
not the mouth}
Anus
3. What are the four stages of food processing? Why does crossing the plasma membrane matter
to gut function?
key to digestion nutrients crossing -
1. Ingestion plasma membranes

. In the “train of thought,” what does the
nucleic acids body’s cells get from food? {go further than

“fuel.”}
. What process does this breaking?
Enzymes break the bonds in these
molecules by adding water a process
,
called enzymatic hydrolysis.
catabolic =
breakdown

. What do three of the four macromolecules
get broken down to?
carponydrates simple sugars
Proteins amino acids
