What is being demonstrated in
the tubes below?
Absorption of
nutrients into the
blood stream
The figure
best
illustrates?
Why starch needs
to be digested.
The process we performed in class
with balloons is best described
as?
Passive
transport
or diffusion
The process illustrated in the
Figure is best described as?
Active
transport
The total surface area
of the rectangular
prism in the figure is?
138
2
cm
What do you think
amylase will do
when you mix it
with a starch
solution?
Amylase will break
starch into simple
sugars (glucose).
Based on the lab we did in class what
would the results be in the table below.

What is
mechanical
digestion in the
mouth.
chewing and
crushing your food
This is what
softens and
moistens food in
mouth?
This is saliva and
another example
of mechanical
digestion
Salivary glands
secrete this
enzyme into the
mouth?
Amylase
What is the
function of HCl
(Hydrochloric
Acid) in the
stomach?
Lowers the pH of the
stomach contents to
activate the pepsin /
make it do its job.
What nutrient
starts its digestion
in the stomach?
Protein
How does your
body use
protein?
To repair
tissue and
build muscle
Gastric juice is made
of_______________
and_______. It is
found in the
_____________.
Gastric juice is made
of__HCl and
pepsin_and found in
the
___Stomach____.
Circular, Longitudinal,
and Diagonal muscles
work together to
achieve mechanical
digestion in this organ
the stomach
Why are active and
passive transport
both needed in the
absorption of digested
nutrients into the
body?
absorption sometimes
requires cellular
energy
and/or
not all nutrients can be
absorbed by diffusion
What helps increase
the amount of
nutrients absorbed
in the small
intestine?
What are villi
and
microvilli?
This alkaline/basic
solution helps
neutralize the acidic
stomach juice, when
it enters the
duodenum
What is
pancreatic
juice?
Fat is broken
down in this
organ.
What is the
small
intestine?
This organ has the
largest internal
surface area of the
digestive system to
absorb nutrients
What is the
small
intestine?
What occurs in the
colon (large
intestine) that our
body needs in order
to work properly.
•Transport
undigested waste
•absorb water
•absorb minerals
Why does our body
need water to
function properly?
It transports
nutrients and
waste in our
body
What is the
difference between
large intestine and
colon?
Nothing, they are
synonymous
(same thing)
Dead cells,
undigested food,
and bacteria are
stored here
What is the
Rectum?
How does food
move through the
digestive tract?
Peristalsis
