Question

Now explain your diagnosis. Start your argument by something like this:
“ My Group believes that Elisa has/does not have___. I think that she does/does not have the__ condition because.”

(Then, explain how molecules move through the body when someone has the condition you investigated, and compare that to Elisas test results.)

Answer 1

Answer:

Today, you will finally diagnose Elisa! You’ll share your expertise with your group, explaining the

condition you investigated and how it could affect Elisa’s body systems. Then, you’ll receive Elisa’s

test results and compare them to the Sim tests you did earlier. Together, your group will consider

the possible claims about why Elisa is tired and decide on a diagnosis that is supported by all the

available evidence. You’ll craft a written argument supporting this diagnosis. This will help Elisa get

the treatment she needs.

Unit Question

• How do the trillions of cells in the human body get what they need to function, and what do

the cells do with the things they absorb?

Chapter 2 Question

• What is happening in Elisa’s body that could be preventing molecules from getting to her cells?

Key Concepts

• Cells can only use molecules that are small enough to enter a cell.

• The respiratory system brings in oxygen molecules from the air. These oxygen molecules are

already small enough to fit into cells.

• The digestive system brings in food and breaks it down into smaller molecules, such as

glucose and amino acids, that can fit into cells.

• The circulatory system transports glucose, oxygen, and amino acid molecules to every cell in

the body.

• In a functioning human body, body systems work together to deliver glucose, oxygen, and

amino acid molecules to the cells in the body.

• A problem with a body system can result in fewer oxygen, glucose, and/or amino acid

molecules getting to the body’s cells.
