Document Summary
Stress any factor that interferes with the normal limits of operation of an organism. Homeostasis the maintenance of normal limits of body functioning. Humans can adapt biologically and culturally but in adapting to stresses culturally, we can introduce other stresses as a result. Human adaptation operates on physiologic, developmental, genetic, and cultural levels. Plasticity the ability of organisms to respond physiologically or developmentally to environmental stresses. Climate and human adaptation expansion of humans possible due to adaptations to range of temperatures around the world. Humans can maintain a constant body temperature only under certain limits. Vasodilation is important in heat loss: opening of blood vessels move internal heat to outside skin, heat can then be transferred to the environment through radiation, convection, and evaporation. Differences in morphological variations (e. g. size and shape of body and head) affects person"s ability to handle temperature stress including nose size + shape.
