Document Summary
Homeostasis-is the physiological concept that refers to the maintenance of a relatively stable in environment in the face of external variability. Feedforward regulation- feedforward regulation is generally a response to sensory information predicts a particular physiological change. Ex- transtion between post pregnant and pre pregnan. End product is what untimely slows down the rate. Ex- open a door, prepare to open a door. Ex- eat a meal-> massive chemical changes, all the nutrients that were eaten makes you glu increase. Endocrine response-> the smell/ and see even before the food has entered your mo which helps to keep blood glucose levels relatively stable once you actually start digesting/absorbing the food. Ex- arm movement- prepare to open the door. Regulatory molecules(mostly proteins)- regulatory proteins modify biological processes turnin on or off, speeding them up or down, etc. Critical for the maintenance of homeostasis at the cell higher levels.
