Assimilation vs. Absorption
A fight to the death? I think
not!

Location location location! (Of
absorption)
a 300m squared surface area
the lumen of the small
intestine breaks polypeptides
(once proteins) into amino
acids, and fat globules
(insoluble in water) into fatty
acids and glycerides.
The epithelium of the small
intestine (brush border) also
breaks poly peptides into
amino acids, and tiruns
disaccharides of
carbohydrates into
monosaccharides.
Location of assimilation-nation
The food that is digested is
absorbed into the blood and
lymphatic systems (returns
proteins and cells to the
blood).
The digested food in the
blood stream reaches the
liver. Here, the excess
glucose is stored as glycogen
to be used in times of need.
The cells take the glucose
they need from the blood
directly for respiration. The
amino acids are used to
form new proteins.
How are these silly systems
structured? (Absorption)
What about assimilation??
Occurs in the liver
Liver cells contain
Ribosomes
Lysosomes
Mitochondria
What is the point to this MADNESS?
The whole point of absorption and assimilation is to get cells all
around the body the nutrients that have been ingested.
Absorption of nutrients and compounds into the small intestine
allows certain molecules to be transferred directly to the blood, or
to be sent to the liver for further breakdown.
Once this has occurred, cells such as the heart or skin still
haven't received the nutrients or proteins that they need. This is
where assimilation comes in. Nutrients and compounds travel
through the bloodstream from the small intestine and the liver.
They are then given to each cell in the body along with oxygen,
allowing all cells to continue to function with the compounds they
need.
