Document Summary
Animal physiology: study of animal function helps in understanding: the fundamental biology of all animals, human health and disease, the health and disease of nonhuman animals of importance in human affairs (p. 11-14) Dynamic state of body constituents: atoms of animal bodies (material building blocks) are in dynamic exchange with the atoms in the environments: organized systems requiring energy to maintain this organization. The internal environment can either vary or be kept constant when external environment changes. Conformity: internal = external; disadvantage: cells are subjected to change with external conditions, advantages: avoids energy costs to keep internal different from external environment. 1 to 3: response to external environment, 4 to 5 is internal (p. 161-166) Energy metabolism: the sum of the processes by which animals acquire energy, channel energy into useful functions, and dissipate energy from their bodies; (energy, physiological work is the capacity to increase order).
