Chapter 48.8, Problem 1SB
Summary Introduction
To review:
The mechanism by which thermoreceptors and negative feedback mechanism regulate temperature in the endotherms.
Introduction:
Endotherms are warm blooded animals (birds and mammals), which obtain energy from the internal

Compare the costs and benefits of being an endotherm, and describe strategies endotherms use to adjust their body temperature.
Why are concurrent temperature exchange systems not a part of homeostatic temperature control in endotherms?
Explain how the hypothalamus directly detects the temperature (is a sensor in a feedback loop)?

- Draw a negative feedback loop for maintaining homeostasis for thermoregulation where your body temperature is above the set point. In your drawing, include the stimulus, sensor, integrator, effector, and the arrows between the components to indicate how they all relate (be sure to indicate what each of these components are in your body, for example, what is your integrator). Further, answer the following two questions. First, what might be different between the response of an endothermic and an ectothermic animal in maintaining homeostasis? Second, describe what a negative feedback loop is and how it pertains to homeostasis.arrow_forwardFrom the list of strategies for dealing with harsh cold environments, choose those that an ectotherm would employ.
