- When faced with a sudden drop in environmental temperature, an endothermic animal will _______. a. experience a drop in its body temperature b. wait to see if it goes lower c. increase muscle activity to generate heat d. add fur or fat to increase insulation(a) Write down an equation expressing the thermal balance between the human bodyand its environment.(b) Under what conditions is the temperature of the deep tissues of the human bodygoing to change? Discuss the physiological mechanisms which the body employs to adjustsuch an imbalance. How can the air conditioning engineer, through an appropriate manipulationof the environment, assist the body in feeling comfortable?When faced with a sudden drop in environmental temperature, an endothermic animal will ________.a. experience a drop in its body temperatureb. wait to see if it goes lowerc. increase muscle activity to generate heatd. add fur or fat to increase insulation
- 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?Which of the following would increase the rate of heatexchange between an animal and its environment?(A) feathers or fur(B) vasoconstriction(C) wind blowing across the body surface(D) countercurrent heat exchangerThe rate of heat loss in a mammal is regulated bya. the degree of blood flow at the surface of the skin.b. the amount of perspiration.c. behavioral adaptations.d. air currents near the animal’s body.e. all of the above.
- Heat exchange with the environment depends on the surface area-to-volume ratio of the body. Assuming that the body shape of an animal is at least somewhat spherical, a considerable decrease in body size would _______ the surface area-to-volume ratio, and the ability to exchange heat with the environment would _______. A. increase; increase B. increase; stay about the same C. increase; decrease D. decrease; increase E. decrease; stay about the sameHe reasons that a liter (about a quart) of water weighs 1000 g, whichis equivalent to 580,000 cal, or 580 kcal, of heat when lost as sweat.Therefore, instead of reducing his diet by 580 kcal/day, he believesthat losing a liter of sweat every day in the sauna will cause him tolose about a pound of fat a week. Will this approach work? Explain.Given that humans thermoregulate, explain why your skin is coolerthan your body core.
- 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 some diseases, an infection causes a high fever, resulting in a crisisstate. Once body temperature begins to return to normal, the person ison the way to recovery. If you were looking for symptoms in a personwho had just passed through the crisis state, would you look for dry,pale skin or flushed, wet skin? Explain.Which of the following statements is True?a. Ectotherms generate most of their body heatmetabolically.b. Ectotherms include birds and mammals.c. Ectotherms experience variable body temperatures.d. Ectotherms are known as “warm-blooded” animals.
