Connection of relationship between two things.
interaction
organs
endoscopy
selectively permeable
Structures inside the body such as the heart, lungs, etc., that serve a particular function.
interaction
organs
endoscopy
selectively permeable
Match the following body systems to its correct function.
Pumps blood to all parts of the body providing nutrients and oxygen to every cell, and removes waste products, such as carbon dioxide.
circulatory system
Helps all parts of the body communicate with each other by sending messages.
nervous system
Oxygen is taken into the body and carbon dioxide is removed as waste.
respiratory system
Match the following body systems to its correct function.
Breaks down large food molecules such as carbohydrates, fats, and proteins into smaller nutrients for the body to absorb.
digestive system
Provides the framework and support for the body.
skeletal system
Allows the body to move.
muscular system
A procedure where they extend a camera on a long cable through a patient's mouth to take images.
interaction
organs
endoscopy
selectively permeable
The cell membrane is selectively permeable. What does that mean?
The cell membrane lets certain molecules pass through but blocks others.
The cell membrane moves around the cell.
The cell membrane can change into a different organelle.
The cell membrane has holes that lets everything pass through it.
The first step of digestion. Food is broken down physically into smaller pieces and also chemically by amylase in this organ.
A muscular tube that connects the mouth to the stomach.
A large, muscular sac that continues mechanical and chemical digestion. The majority of digestion occurs here.
In this organ, digestion continues and absorption of small food molecules into the bloodstream occurs.
The final step of digestion occurs in this organ. Water is absorbed from food and the remaining material is eliminated from the body.
Match the large food molecules to the small molecules they get broken down into.
fats
fatty acids
proteins
amino acids
carbohydrates
sugars
The movement of molecules from a higher amount to a lower amount until both sides are equal.
dialysis tubing
diffusion
indicator
absorption
A material that changes color when it comes in contact with a specific molecule.
dialysis tubing
diffusion
indicator
absorption
When food molecules go through the openings/gates in the wall of the small intestine and into the body.
dialysis tubing
diffusion
indicator
absorption
Diffusion is the movement of molecules from a (a) concentration to a (b) concentration until both sides are (c) .
Why did we use dialysis tubing in our lab?
it is cheap
it is selectively permeable
it is clear
just what we had around the classroom
We used the dialysis tubing as a model. Which digestive organ was the dialysis tubing supposed to represent?
small intestine
large intestine
stomach
esopaghus
An example of a large carbohydrate is (a) which then gets broken down into a simple sugar called (b) .
Fill out the table provided.
orange
black
blue
brown
starch
glucose
A food molecule that is not broken down, leaving the body the same way it entered it.
fiber
molecules
atoms
enzyme
Made up of more than one atom. Can be large (starch, protein, fat, etc.) or small (glucose, amino acid, fatty acid, etc.).
fiber
molecules
atoms
enzyme
The smallest unit of matter. Needs to combine to make molecules.
Carbon (C)
Oxygen (O)
Hydrogen (H)
fiber
molecules
atoms
enzyme
Molecule that helps with body functions, such as digestion.
fiber
molecules
atoms
enzyme
Match the following to the correct category.
Produces a new substance from an old one.
Can release energy.
carbohydrate -> sugar
fat -> fatty acid
protein -> amino acid
Only changes how something looks.
melting an ice cube
dissolving sugar into water
shredding paper
breaking an egg
saliva breaking down starch into glucose
chewing food
The process of breaking down food molecules by chemical means in the stomach and physical means in the mouth.
product
cellular respiration
digestion
reactant
What is the name of the enzyme in saliva that breaks down starch into glucose?
glucose
sucrose
enzyme
amylase
Finger-like structures located in the small intestine that help with the absorption of molecules.
cells
villi
tissue
fuel
Microscopic structures that make up different parts of our bodies.
cells
villi
tissue
fuel
Any material/matter that can react with other substances so that it releases energy.
cells
villi
tissue
fuel
A group of cells that work together to perform a function.
cells
villi
tissue
fuel
(a) is a process that occurs in (b) that provides them with (c) .
Correctly label the reactants and products in cellular respiration.
reactants
products
Place the following substances of cellular respiration in the appropriate category.
glucose
oxygen
energy
carbon dioxide
water
As villi get taller they have (a) cells surrounding them, allowing for (b) food molecules to be absorbed into the blood stream.
Match the following substances to what happens to them in the digestion system.
starch
protein
fat
sugar
amino acid
fatty acid
water
fiber
What part of M'Kenna's digestive system was significantly different from a healthy person?
mouth
large intestine
small intestine
stomach
Why can villi only absorb small food molecules?
They are located in the small intestine and that is why it is called the small intestine.
The villi are repulsed by large molecules.
The gates of the villi are too small for large molecules.
Our body would hurt itself if it tried to absorb large molecules.
M'Kenna's small intestine is not absorbing enough nutrients. As a result, what food molecule is her body burning instead of storing?
fiber
proteins
fats
carbohydrates
Why is there a shortage of food molecules entering M'Kenna's bloodstream?
M'Kenna's villi are too tall causing less food molecules to get absorbed.
M'Kenna's villi are too tall causing more food molecules to get absorbed.
M'Kenna's villi are too smooth causing less food molecules to get absorbed.
M'Kenna's villi are too smooth causing more food molecules to get absorbed.
What food molecule is causing problems for M'Kenna and she should avoid eating?
proteins
carbohydrates
fats
fiber
What disease does M'Kenna have?
Celiac Disease
Irritable Bowel Syndrome
Crohn's Disease
Colitis
Last night Jane began to feel like she had a stuffy nose. Today she thinks she has a cold. She went to the doctor and her temperature was 102 degrees and her white blood cell count was high, indicating she has an infection.
