For example, if it starts to get hot, the thermostat responds by cooling down the room, much like the body would take measures to cool itself down if it started to hot. Feedback is important in order to keep the body system relatively stable and adaptive. Negative feedback is when the response hinders the stimulus. (ex. low blood pressure go through response to raise blood pressure) Positive feedback is when the response continues the reaction. 5. p.11 in anatomy lab manual 6. membrane any sheet or partition; a layer consisting of an epithelium and the underlying connective tissue Function covers and protects other structures in the body Mucus Membrane Any membrane reachable through a natural opening of the body Continuous sheet of simple squamous epithelial cells with their underlying loose connective tissue Kept moist; Mucus is ciliated to move objects, secretes and absorbs, has columnar epithelium Funct ...
