Slide 4: function: what does something do, structure is adapted for function, bird foot: two different adaptations, same bones, same joints: one adapted to swimming, other to grabbing prey.

Intra: inside: most of body fluid, extra: outside, two subcategories, blood plasma: fluid portion of blood. Inter: in between: stital: standing, dissolved components: nutrients, electrolytes. Slide 10: physiological variable: what you are controlling, set point/normal range: number for which regulation always returns the variable, set by controller (control center, integrator, takes in info and compares it to set point, ex. Hypothalamus: controls temperature set point, compares info: sensor/ receptor: monitors variable. Integrating control center: receives info and compare: needs afferent pathway to sense stimulus, effector: carries out response, efferent pathway: control center instructs response.
