Document Summary

Physiology is the study of living things and how they function. Physiology helps us understand how the body works, from the smallest part (cell) all the way to the whole body. The maintain of a relatively stable internal environment. We have a set point that dictates the level of certain variables. The goal is to maintain these variables within a tight range based on the set point. Stimulus -> sensor -(signal to integrating centre)-> integrating center (cns), the receiving point - (signal to effector to initiate change)-> effector - output-> stimulus temp. In a negative feedback system, the feedback reduces the difference between the desired set point and the actual value; ie. it works to reduce. Phospholipid has one polar head (hydrophilic) and non-polar head (hydrophobic) In bilayers, the non-polar tails are facing each other and the polar heads facing intercellular and extracellular fluid intercellular and extracellular fluid.
