Document Summary
Physiological processes are shaped by evolution: genotype-phenotype-environment, evolution-development, phenotypic plasticity and the nature of adaptation. Physiological processes are usually regulated: homeostasis- maintenance of internal constancy. Reductionism is when you look at the pieces to understand the whole: e. g. regulation of the thermogenin gene to understand control of nonshivering thermogenesis. Emergence is the realization that the whole is more than the sum of the pieces: e. g. the effects of the gut microbiome on cardiovascular health. Most traditional physiologists study processes to better understand the human condition (like health and disease) Mass specific comparisons are different gram of elephant has less oxygen intake than gram of mouse but elephant takes in more oxygen than the mouse. Consider what a physiologist might ask about the long neck of the giraffe: Interdependence of evolution and development: neck length causes different cardiovascular demands, mouse and giraffe have the same number of neck vertebrae, there is just a difference in the size of them.
