Question
Chapter 1, Problem 25RA
Summary Introduction
To analyze:
Range of temperature values.
Introduction:
The range of values are the maximum and minimum values between which a given parameter remains in equilibrium. While performing an experiment the range for different physiological conditions is set. The feedback mechanism helps in maintaining normal physiological conditions.

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.
