Nutrient Absorption Gallery Walk
STATION 1: Food Station- Look at each meal and answer the following questions.
1. What does food provide the body with? Circle all that apply.
energy
glucose
oxygen
water
carbon dioxide
nutrients
calories
2. List each food item found in the meal. Then, tell what biomolecules it contains, where in the digestive tract it is
broken down, and what enzymes are involved. List them all! Ex: steak, stomach- pepsin for protein
1. Meal 1: You go to Applebee’s and order this double bacon cheeseburger and fries.
Bun, mouth and small intestine – salivary amylase and amylase for carbohydrate
Bacon & Beef patty, stomach and small intestine – pepsin and peptidase for protein
Cheese and bacon, small intestine – bile and lipase for lipids
French fries, – salivary amylase and amylase for carbohydrate; bile and lipase for lipids
a. What biomolecules are found in this food?
Carbohydrates
Protein
Lipids
b. Which accessory organ(s) would be used most to break down this high-fat meal?
Liver would produce the bile to break down this high-fat meal.
2. Meal 2: You go to Salata and order this fruit, nut, cheese, and cracker plate for a snack.
Fruit, mouth and small intestine – salivary amylase and amylase for carbohydrate
Nuts, stomach and small intestine – pepsin and peptidase for protein; small intestine - bile and lipase for
lipids
Cheese, small intestine – bile and lipase for lipids
Crackers, mouth and small intestine - salivary amylase and amylase for carbohydrate
a. What biomolecules are found in your snack?
Carbohydrates
Protein
Lipids
b. Which accessory organ(s) would be used to regulate the sugar in your snack?
Pancreas would produce insulin to regulate blood sugar levels.
3. Meal 3: You go to Snap Kitchen and pick up this balanced meal (Salmon, broccoli, and rice).
Salmon, stomach and small intestine – pepsin and peptidase for protein; small intestine - bile and lipase
for lipids
Broccoli, mouth and small intestine – salivary amylase and amylase for carbohydrate
Rice, mouth and small intestine – salivary amylase and amylase for carbohydrate
a. What biomolecules are found in your snack?
Carbohydrates
Protein
Lipids
b. Which accessory organ(s) would be used to begin the breakdown of the rice?
Salivary glands in your mouth would produce salivary amylase to breakdown the starch in the rice.
STATION 2: Sheep Pluck Questions – Look at the sheep pluck in the tray and answer the questions below.
1. What organs do you see when you view the external anatomy of this specimen?
Heart, lungs, trachea, and part of diaphragm
2. Find the trachea. Explain why does it not collapse during respiration?
The trachea has cartilage rings to keep the airway open.
3. What is the epiglottis and why is it so important to have a working epiglottis?
A flap of tissue called the epiglottis covers the entrance to the trachea (glottis) when you swallow. It prevents
food or water from going into your lungs and you choking to death!
4. Which respiratory structure is surrounded by capillaries? Alveoli. This is where gas exchange occurs.
5. How many lobes does the left lung have?___2 (bc the heart takes up room on this side)__ How many lobes
does the right lung have?___3___
6. The respiratory system provides oxygen to the __circulatory__ system.
7. Carbon dioxide from cells is delivered from the circulatory system back to the ___respiratory____ system so it
can exit the body.
8. What muscle aids in respiration that lies at the bottom of the chest cavity? Explain its role in breathing.
Diaphragm. Inhaling (Breathing in) Ribs rise, diaphragm contracts, fills chest cavity.
Exhaling (Breathing out) Passive event. Ribs lower, diaphragm relaxes, empties chest cavity.
STATION 3: Sheep Heart Questions – Look at the sheep heart in the tray and answer the questions below.
1. The right ventricle pumps oxygen (rich or
poor) blood into the (lung or body).
2. The left ventricle pumps oxygen (rich or
poor) blood into the (lung or body).
3. What part of the heart is responsible for making sure the blood is pumped in one direction?
Valves keep blood flowing in one direction.
4. What is the importance of the septum (the center part of the heart muscle)?
The septum prevents oxygen-rich blood from mixing with oxygen-poor blood. This is unique to the 4
chambered heart.
5. The pumping of the heart is the force that directly _______.
A. moves blood through the arteries
C. sends nerve messages to the brain
B. causes the lungs to expand
D. allows movement of the muscles
6. Which two body systems interact to send oxygen throughout the body?
A. Integumentary and muscular systems
C. Respiratory and circulatory systems
B. Skeletal and reproductive systems
D. Digestive and nervous systems
7. What two body systems are most useful in getting nutrients from the food you eat to your brain?
A. muscular and endocrine systems
C. nervous and circulatory systems
B. nervous and digestive systems
D. circulatory and digestive systems
STATION 4: Heart Rate Questions – Follow the directions below.
1. Examine your partner’s radial pulse. To do this, follow these steps:
a. Have your partner sit in the chair quietly, remaining as relaxed as possible.
b. Locate the pulse by placing your index and middle fingers over the radial artery on the anterior surface of
the wrist. (Do not use your thumb for sensing the pulse because your thumb itself has an artery.)
c. Note the characteristics of the pulse. Describe it as regular or irregular, strong or weak, hard or soft?
d. To determine the pulse rate, count the number of pulses that occur in 1 minute. This can be
accomplished by counting pulses in 30 seconds and multiplying that number by 2.
2. Repeat the procedure and determine the pulse rate in each of the following conditions:
a. immediately after standing
b. 2 minutes after standing quietly
c. immediately after 60 - 90 seconds of jumping jacks (omit if the person has health problems).
d. 2 minutes after exercise has ended.
3. Complete the table in the results section.

STATION 5:
In this station you will diagram the pathway of oxygenated (O2 rich) and deoxygenated (O2 poor) blood in various
situations. Pick a side (right or left) of the heart. The side you pick will determine which card you pick up, oxygenated
(red card) or deoxygenated (blue card). Each member of the group will complete one of the following scenarios by:
1. Walking the actual pathway, and
2. Diagraming the pathway you take on the
provided template. Color-code your pathway
using red and blue markers or colored pencils.
** I completed scenario number ____1______.
Scenario 1: You studied for the upcoming
Nutrient Absorption test, but when you start
taking the test you realize you didn’t study
enough. Your brain goes into overdrive trying
to remember all the facts your teacher taught
you. Diagram the appropriate pathway of
blood.
Scenario 2: You are right-footed and a soccer
ball was kicked towards your direction. You
don’t want to seem athletically-challenged so
you decide to kick the ball back. Diagram the
pathway blood will take to provide nutrients
your leg cells will need in order to create the
necessary energy to kick the ball away.
Scenario 3: You sprained your right ankle trying
to be cool and kick a soccer ball back to soccer
players. When trying to climb the stairs the
next day to get to biology class you have to rely
on your left-leg. Diagram the pathway blood
will take to provide nutrients your left leg cells
will need in order to create the necessary
energy to climb the stairs.
