Document Summary
Time in the lives of animals: physiology changes in five frames. Regulatory process that maintain homeostasis must change from time to time. 2 categories for time frame in which physiology can change: responses of physiology to changes in the external environment, internally programmed changes of physiology. 5 time frames: acute changes, chronic changes, evolutionary changes, developmental changes, changes controlled by periodic biological clocks. Changes in physiology that are responses to changes in the external environment. Internally programmed to occur whether or not the external environment changes subjected to change in external environment acute & chronic response. Physiology responds to changes in the external environment in 3 time frames. Acute responses exhibited in 1st minutes/ hours after environment change. Chronic responses exposed after prolonged exposure to new environmental conditions. Acute and chronic responses differ because of the time it takes for the biochemical and a(cid:374)ato(cid:373)i(cid:272)al restru(cid:272)turi(cid:374)g of a(cid:374)i(cid:373)al"s (cid:271)od(cid:455)
