Document Summary
Read up on chapters 2, 4, and 5 in the biol 273 course textbook for review (not covered in. Study of structure and function of a living organism and its component parts. Function more physiology (focus of this course: understanding physiology requires a large vocabulary of new items, learning physiology is similar to learning a new language. Small number of concepts unit physiology: structure/function relationships: structure is very closely tied with the function (ie. heart, biological energy: atp is the energy currency of the body not the only high energy molecule. Information flow: more related to signal transduction rather than central dogma: homeostasis: balance relatively stable internal environment (equilibrium) Levels of organization: chemical atoms and molecules, cellular e. g. neuron, lymphocyte, tissue collection of cells (e. g. connective) there are four main tissue types, organ structural unit made of tissues (e. g. heart, organ system integrated group of organs, organism individual form of life, community, ecosystem, biosphere.
