Simulated thermoregulation in endotherms and ectotherms Chris Prestridge Shippensburg University 17 October 2012 Objectives: * To determine the effects of fat and/or fur on the thermal conductance of endotherms with a decreasing environmental temperature * To determine the effects of glycerol‚ antifreeze‚ and various concentrations of saline on freezing point depression Null hypotheses: * Fat and fur have no direct relationship with thermal conductance. * Glycerol‚ antifreeze

Thermoregulation is the “maintenance of a steady body temperature even under a variety of external conditions” Harvard. Based on the process of thermoregulation‚ animals are divided into two groups‚ ectoderms and endotherms. Ectoderms are animals that are poor thermoregulators‚ having their body temperature determined by the ambient temperature. Animals that fall into this category are reptiles‚ amphibians‚ and fish. On the other hand‚ endotherms are animals that can thermoregulate and keep their

within its internal environment. Endotherms are “warm blooded” animals that produce and maintain their own internal body heat. Most mammals and a few birds‚ are endotherms; this is beneficial because the enzymes in the body that carry out metabolic processes have an optimum temperature at which they function‚ having the body constantly be‚ or be close to‚ this optimum internal temperature means life processes never have to cease. The opposite of endotherms are ectotherms‚ animals such as reptiles and

Australian ectotherms and endotherms A- TYPES OF TEMPERATURE REGULATION 1- The cat‚ human and platypus could be described as true endotherms‚ as they all maintain a relatively constant internal body temperature that is independent of the external temperature. As the environmental temperature rises from 5C to 40C‚ the humans body temperature remains constant‚ the cat’s and the platypus’ increases by around 3▫C. 2- The lizard and echidna are ectotherms as their body temperature fluctuates according

Dinosaurs Were Endotherms Jiawei Tan‚ 30120159 Abstract: Whether dinosaurs were warm-blooded or cold-blooded is one of the most heated controversies since 19th century. This article is to suggest that dinosaurs were endotherms‚ which means they were warm-blooded. In this paper‚ I will list some evidences that indicate dinosaurs were more similar to mammals and birds rather than cold-blooded animals‚ such as reptiles. Evidences will be shown with comparison among dinosaurs‚ warm-blooded animals

Homeostasis - Thermoregulation Homeostasis is the ability of a cell or organism to maintain a stable internal environment despite fluctuating external environmental conditions. An animal will maintain this state of equilibrium through adjustment mechanisms that keep the conditions of its cells and body within a narrow range (SOC 2 n.d.). Homeostasis is crucial to the survival of an organism‚ by maintaining a stable environment‚ it enables cells to be functioning optimally‚ giving an organism the

Thermoregulation is the system in which organisms maintain a constant internal body temperature in a constantly changing external temperature. It is important for our bodies to maintain conditions within tolerable limits to ensure the human body functions healthily.

THERMOREGULATION IN THE NEONATE By: Shubhada Ponkshe [pic] INTRODUCTION: Thermoregulation is a critical physiologic function that is closely related to the transition and survival of the infant. An understanding of transitional events and the physiologic adaptations that neonates must make is essential to helping the nurse provide an appropriate environment and help infants maintain thermal stability. Optimizing the thermal environment has proven significant for improving the

Thermoregulation: Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries even when the surrounding environment is very different. For humans it is the process the body goes through to make sure it doesn’t overheat or get too cold. The process of ATP production in cells via cellular respiration produces the heat energy that is needed to allow the body to maintain a constant warm core temperature. Hypotherms (Warm blooded animals) are able to keep
