The mouse is endothermic and regulates its body temperature through homeostasis. The lizard is ectothermic and its body temperature is dependent on the environment. Many endotherms have a larger amount of mitochondria per cell than ectotherms. This enables them to generate heat by increasing the rate at which they metabolize fats and sugars ...
Thus, an endothermic reaction generally leads to an increase in the temperature of the system and a decrease in that of the surroundings. [1] The term was coined by 19th-century French chemist Marcellin Berthelot. [3] The term endothermic comes from the Greek ἔνδον (endon) meaning 'within' and θερμ- (therm) meaning 'hot' or 'warm'. [4]
main definition: Thermal decomposition is the breakdown of a compound into two or more different substances using heat, and it is an endothermic reaction Examples [ edit ]
Simplified control circuit of human thermoregulation. [8]The core temperature of a human is regulated and stabilized primarily by the hypothalamus, a region of the brain linking the endocrine system to the nervous system, [9] and more specifically by the anterior hypothalamic nucleus and the adjacent preoptic area regions of the hypothalamus.
Older set of terminology shown in Parts of the Human Body: Posterior and Anterior View from the 1933 edition of Sir Henry Morris' Human Anatomy. Many of these terms are medical latin terms that have fallen into disuse. Front: Frons - forehead; Facies - face; Pectus - breast; Latus - flank; Coxa - hip; Genu - knee; Pes - foot; Back: Vertex ...
Case (c) depicts the potential diagram for an endothermic reaction, in which, according to the postulate, the transition state should more closely resemble that of the intermediate or the product. Another significance of Hammond’s postulate is that it permits us to discuss the structure of the transition state in terms of the reactants ...
The internal human body includes organs, teeth, bones, muscle, tendons, ligaments, blood vessels and blood, lymphatic vessels and lymph. The study of the human body includes anatomy, physiology, histology and embryology. The body varies anatomically in known ways. Physiology focuses on the systems and organs of the human body and their functions.
Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.
