100

This is the first location that digestion takes place. It involves mechanical and chemical digestion. 

What is the mouth?

100

This is the main waste gas produced during the chemical reaction of cellular respiration.

What is carbon dioxide

100

This organ is responsible for pumping blood, which carries food molecules and oxygen to all cells.

What is the heart?

100

What happens to fiber that is not broken down?

It is too big to be absorbed and is excreted as solid waste.

200

This long tube in the digestive system is where most food molecules are broken down into smaller ones and absorbed into the blood.

What is the small intestine?

200

Exercising would generally cause glucose in your blood to ________________

What is decrease?

200

Damage to the villi in M'Kenna's small intestine reduces the total area available for absorbing food molecules, which leads to this symptom. 

What is diarrhea?

200

This gas combines with glucose to release energy in the cells. 

What is oxygen? 

300

The process that uses chemical reactions to break down large food molecules (like starches and proteins) into smaller ones (like simple sugars and amino acids).

What is digestion?

300

A chemical reaction that uses glucose and oxygen to create energy for processes needed for cells to carry out of all their functions. 

What is cellular respiration? 

300

This happens when a person consumes more calories (energy) than their body needs at that time. 

What is gain weight/fat?

300

These tiny units are where the chemical reactions of cellular respiration and the rearrangement of matter for growth and repair primarily take place.

What are cells?

400

These tiny, finger-like structures lining the small intestine increase the surface area for absorbing food molecules.

What are villi?

400
The lungs have these sacs that allow oxygen to be inhaled and absorbed into the body and carbon dioxide to be exhaled.

What are alveoli? 

400

M'Kenna's inability to concentrate and lack of energy are symptoms that point to problems in her body getting enough of this.

What is energy (or simple sugars/glucose)?

400

This gas is released as a product of cellular respiration that occurs when we "burn" food in our cells for energy. 

What is carbon dioxide? 

500

This body system works with the digestive system to transport absorbed food molecules to cells all over the body.

What is the circulatory system?

500

When food is "burned" in the body, its atoms are rearranged but their total number and type remain the same, illustrating this fundamental law.

What is the Law of Conservation of Mass

500

This system, which includes the lungs, brings the oxygen required for cellular respiration into the body.

What is the respiratory system?

500

The respiratory system takes in oxygen that the muscular system needs. 

What are the ways systems work together (interact with one another)?
