PPT-Thermoregulation Maintenance of body temperature

Ecotherms Endotherms Metabolic Response to External Temperatures Responses to Cold and Heat Hypothalamus Torpor Hibernation Estivation Thermoregulation From Australia to the Arctic Tundra there is a vast range of temperatures that humans and other living things can survive in. It is lowest in the early morning between 4 and 6 am and highest in the early evening between 6 and 8 pm Normal temperature is about 37730C or 986730F However it can be as low as 361730C 97730F in the early morning to a high of 372730C 99730F in the Thermoregulation. Homeostasis. – Is the stable, constant temperature for the human body to most effectively function. This is around 37 degrees Celsius.. Hypothermia. – is the lowering of the core body temperature to such an extent that the body does not function normally. This is defined at 35 degrees . 1 Thermoregulation Poikilothermy -temp directly controlled by environmentHomeothermy -Body temp. remains relatively constantEndothermic = internal heat source = Controlling Temperature. What is thermoregulation?. Learning Objectives. Understand what is meant by thermoregulation.. Understand how the body detects rises and falls in body temperature.. Understand what the body does to bring temperature back to normal levels.. Maintaining a stable body temperature. . Why do organisms need to maintain a stable body temperature??. Optimum Temperatures. Organisms must keep their body temperature between a specific range in order to survive.. Olivia Jones. What is Thermoregulation?. The ability of an organism to keep its body temperature with in a certain range when temperature surrounding is extremely different.. How temperature determines how well snakes . Home and the work place. Conduction. The transfer . of heat through a solid.. Particles . that make up a substance are vibrating all the time . As heat is applied vibrations become more vigorous, therefore increasing Kinetic (movement) Energy.. What is Thermoregulation?. Thermoregulation. refers to the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different.. Physiological Thermoregulation. Cristen. Moore. Westminster nursing school. Circulating Nursing. Being an . . advocate. for patient. . in OR. Pre Procedure. Look at DPC. Fill out whiteboards. Help set up room. Pull medications. Ectotherms. Rely mainly on external energy sources.. Endotherms. - Rely heavily on metabolic energy. Homeotherms. . maintain a relatively constant internal environment.. Poikilotherms. (= . heterotherms. Justin Libaw, MD. 1. Gabriel Sarah, MD. 2. University of California, San Francisco. Updated 12/2019. Disclosures. No relevant financial relationships. Learning Objectives. Define normothermia and describe normal thermoregulation. Instruments used to measure body temperature:. 1. Liquid-filled. i. ) Range 95/110°F. ii) Range 35/42°C. Medical thermometer has a notch to prevent mercury from return back quickly. 2. Electronic (Electronic clinical thermometers). Professor Peter Shepherd. Maurice Wilkins Centre and University of Auckland. Temperature Affects Function of Organisms . The function of cell components changes with temperature. PROTEINS. - protein shape changes with temperature and this affects its function. In particular enzymes work best at certain temperatures (Analogy - why does yeast make bread rise more quickly at warm temperatures than cold temps ? Why do egg whites solidify when heated to much ?). Background. A set core temperature is normally maintained by the body. Thermoregulation is challenged by environmental extremes. Sweating is limited when wearing protective clothing. Research indicates females are less tolerant to hot environments than males.
