Question
Chapter 1, Problem 20RA
Summary Introduction
To review:
The compensatory physiological responses after injecting insulin and to describe the importance of quantitative measurements in physiology.
Introduction:
Glucagon and insulin are primarily responsible for the maintenance of blood glucose levels. Synthetic insulin is widely used by patients having diabetes mellitus. The quantitative measurements of various body parameters are quite useful in observing the physiological effects of different medicines and treatments.

a) Develop a Forrester Diagram, based on the schematic below, for blood temperature
homeostasis. Consider four state variables. Keep in mind that the final goal of the
model is to show how normal body temperature is re-established after a
perturbation.
Of note, if you draw your solution by hand make sure your scan is readable (not just
a bunch of cell phone pictures) and converted to pdf
Using an e-pencil is usually better, or ppt.
Thermoregulation
center in brain is
activated.
Temperature rises
above normal.
Sweat glands secrete
sweat that evaporates,
cooling the body.
Blood vessels
in skin dilate and
heat escapes.
Homeostasis:
Internal body temperature
of approximately 36-38°C
Blood vessels
in skin constrict,
minimizing heat loss.
Skeletal muscles rapidly
contract, causing shivering
which generates heat.
Temperature falls
below normal.
Thermoregulation
center in brain is
activated.
b) Write-up the equations (FDEs) for your Forrester Diagram.

Illustrate the general principle of physiology that describe that physiological processes require the transfer and balance of matter and energy?
In Type 1 Diabetes, the body is unable to maintain homeostasis of blood glucose because the pancreas does not make insulin. Draw a graph to predict how blood glucose levels (mg/dl) would change with time in the 2 hours after consuming sugar in a person with Type 1 Diabetes versus a healthy person.

- Briefly explain these three facts:arrow_forwardAt Kate's next appointment, Paula showed Kate how to use a glucose meter. She instructed Kate to measure her blood glucose level twice a day before and after breakfast and dinner. Paula explains to Kate that her pre-meal blood glucose level should be 110 mg/dLmg/dL or less, and if it increases by more than 50 mg/dLmg/dL, she needs to lower the amount of carbohydrates she consumes. Kate and Paula proceed to plan several meals. Because a meal should contain about 45 to 60 gg of carbohydrates, they combined fruits and vegetables that have high and low levels of carbohydrates in the same meal to stay within the recommended range. Kate and Paula also discuss the fact that complex carbohydrates in the body take longer to break down into glucose and, therefore, raise the blood sugar level more gradually. Kate increased her exercise to walking 30 minutes twice a day. She began to change her diet by eating 6 small meals a day consisting of more fruits and vegetables without starch such as green…arrow_forwardFor each case identify the physiological problem and explain what data you used to come to your conclusion. a) A child’s parent makes an appointment with the doctor because the child is experiencing pain in the pelvis.
