M'Kenna Unit Assessment

Which organs are part of the digestive system that work together to process food?

• Nose, mouth, and lungs

• Mouth, esophagus, stomach, small intestine, and large intestine

• Blood and heart

• Cells and food molecules

How do the respiratory and circulatory systems work together?

• They break down food molecules and absorb them into the body's circulatory system.

• They bring food molecules and oxygen to cells and remove carbon dioxide.

• They store excess food as fat molecules in the body.

• They create carbon dioxide and water and release energy that cells can use.

According to the diagram, what happens to food molecules that are not needed right now?

• They are exhaled through the lungs

• They are stored as fat

• They are used immediately for energy

• They are needed for growth

What is the purpose of the food molecules that are needed for growth?

• To provide immediate energy

• To be stored as fat stores

• To be used to make structures like bone, hair, and muscles

• To be exhaled as carbon dioxide

How are fat stores used for M'Kenna according to the diagram?

• They are converted into carbon dioxide and exhaled

• They are used to make structures for growth

• They are broken down and used for energy in pathway 1

• They are stored indefinitely and not used
