Here's an example of what's due today

Glucose data CER analysis

Wed, Apr 7, 2027 · Week 12 · Human Anatomy & Physiology (Human Body Systems)

Today's goal: Students will analyze blood-glucose data and write a CER explaining how feedback maintains homeostasis.

What a finished product looks like

This is a model of the work you should turn in today. Use it to check your own: match the structure and the level of detail, do not copy it. Your data and wording should be your own.

Worked CER on a parallel case (body-temperature regulation)

Completes: A Claim-Evidence-Reasoning paragraph analyzing a body-temperature graph: a claim about how homeostasis is restored, two specific data-point evidence entries, and reasoning that names negative feedback.

Claim: After a hard run, the body restored normal core temperature through negative feedback.\n\nEvidence: At 0 minutes (just before running) core temperature was about 37.0 degrees Celsius. At 20 minutes it peaked at about 38.6 degrees Celsius, and by 60 minutes it had returned to about 37.1 degrees Celsius.\n\nReasoning: The rise at 20 minutes was detected by the hypothalamus, which triggered sweating and widening of skin blood vessels to release heat. Because the response (cooling the body) opposed the change that triggered it (the rise in temperature), this is negative feedback, and that is why the value came back down near the starting set point of about 37.0 degrees Celsius by 60 minutes.

Blood-glucose curve rising from 90 mg/dL at 0 minutes to a 140 mg/dL peak at 30 minutes, then returning to about 95 mg/dL by 120 minutes.

Also due today: Submit your CER to the Schoology assignment for HBS Endocrine Day 4.

WebXam problem for today's skill

One exam-style question that uses exactly what you practiced today. Try it before you reveal the answer, then read why each choice is right or wrong.

WebXam-style domain: Human Body Form, Function, and PathophysiologySelf-check skill: Reading a blood-glucose graph to identify negative feedback and where it fails

On a blood-glucose graph, a healthy person's level peaks after a meal and returns to baseline within two hours. A person with untreated Type 1 diabetes stays high and does not return. What does the failure to return indicate?
