Suppose at the end of a hard runon a hot day you find that there are no drinksleft in the cooler. If, out of desperation, youdunk your head into the cooler, how might theice-cold water affect the rate at which your bodytemperature returns to normal?
In discussions of feedback in biological systems, negativefeedback is typically emphasized, and positive feedback is oftentreated as an anomaly. In fact, positive feedback is common inreproductive physiology. List two or three examples of positivefeedback. Explain how positive feedback functions to advantagein each case. If possible, discuss whether homeostasis is alwaysideal.
You made early morning run as part of your daily routineexercise during the quarantine period. After your physical activityyou always feel that your heart pounds faster, your breathingintensifies, you sweat rigorously and you feel thirsty too. Relatethese sensations with the specific feedback mechanism.
What effect would swimming in cool water have on body temperatureregulation? What would happen if a negative-feedback mechanismdid not return the value of a variable, such as body temperature, to itsnormal range?
All else being equal, a warm chameleon sitting on a sunny tree branch will experience a decrease in body temperature due to conduction if: O It changes color, and its new hue is a lighter color, reducing the amount of energy the chameleon absorbs from the sun. A cold breeze moves over the chameleon, transferring heat from the warmer chameleon to the cooler, moving ain. It opens its mnouth, allowing water to evaporate from its tongue and cheeks. The branch is cooler than the chameleon, and heat moves directly from the warmer animal to the cooler branch.

Try this experiment to determine the value of serous fluid:First, rub the palms of your hands quickly against one another.The sound you hear and the heat you feel are consequencesof the friction being produced. Now put lotion (our versionof serous fluid) on the palms of your hands and repeat theexperiment. Do you still hear the noise and feel heat from yourhands? What do you think would happen to your body organsif there were no serous fluid?
The feedback loop shown below is an example of negative feedback that uses the narrowing and widening of blood vessels in the skin to regulate body temperature.

Each of the following is one of the five basic characteristics of inflamed tissue except O heat. swelling. redness. bruising. O pain.
When body temperature decreases below the normal range, thermoreceptors in the skin and hypothalamus detect the decrease in body temperature. The heat-promoting center of the hypothalamus is activated, which sends signals to blood vessels and skeletal muscles. In response, blood vessels in the skin constrict and skeletal muscles shiver. Determine the part of this negative feedback loop that serves as the control center. O thermoreceptors O hypothalamus blood vessels and skeletal muscles O body temperature
Give an example of a positive-feedback mechanism thatmay be harmful to the body and an example of one that isnot harmful.
