GOMOYOTERMNY ANIMALS (grech, homoios similar, the same + thermos warm, hot; synonym: gomotermny animals, hematothermal animals) — animals with rather constant body temperature. By. the highest vertebrate animals — birds and mammals belong (including and the person). Relative constancy of body temperature (i.e. a gomoyotermiya) causes independence of course various fiziol, processes in an organism of. from conditions of the surrounding «Wednesday (see. Homeostasis ). Gomoyotermiya are the cornerstone a high level of standard metabolism (heat production) and thin Neyrogumoralnaya regulation fiziol, mechanisms thermal controls (see). Thermal control is carried out by change of size of heat production (chemical thermal control) or thermolyses (physical. thermal control). Chemical thermal control includes change of intensity of oxidizing processes in fabrics of a live organism, degree of an associativity of breath to phosphorylation (see. biological oxidation , Metabolism and energy ) and other processes. To physical. to factors of thermal control belong regulation of a thermolysis (sweating, etc.) and the isolating covers (hair, feather and wool covers, a layer of subcutaneous fat etc.). Change of a functional condition of an organism at. it is accompanied by adaptive change of body temperature. Range of such changes at the person is ranging from 35,0 — 36,0 ° (deep sleep) to 38,5 — 39,0 ° (intensive muscular or cerebration). Constancy of body temperature with insignificant fluctuations around some average size specific to each species of animals, is an objective sign of health. The considerable deviation of temperature in this or that party demonstrates existence patol, processes in an organism.

In spite of the fact that body temperature at. in general it is rather constant, temperature of separate body parts (e.g., hands, foot, a lobe of an ear, a tip of a nose, etc.) more depends on ambient temperature. In particular, in the conditions of low temperature chances of freezing injury of these body parts (see. Freezing injuries ). Besides, distinction in temperature of these or those body parts is the cornerstone thermometry of a body (see) can also serve one of diagnostic characters of some diseases.
