Document Summary
Chapter 1 what is physiology: form dictates function: if you change the shape you change the function. It is not constant but deviates within a range of workability (dynamic constancy: antagonistic effectors maintain conditions within a range called dynamic constancy (sweating or shivering are examples, negative feedback ***watch video*** Involves returning conditions to a set point; input and output are opposites: sensor: determines how far away you are from a set point; detects he change and sends the information to the integrating center or brain. Give an example: the goal of an atom is to have 8 electrons in the valence orbital or just a full valence orbital. In that order hydrogen, carbon, nitrogen, and oxygen make us up! This order indicates increasing electronegativity h is not as electronegative as o. If the two atoms in that bond are next to each other on that list then that bond is a nonpolar bond: examples: h-c; c-n.
