Document Summary
Physiology= the study of the normal functioning of a living organism and its component parts. Defines the functions of our organs, tissues and biochemical reactions and most importantly their interrelationships. Mechanistic - modern understanding, see body as machine, where our mechanisms of action can be explained in terms of physical and chemical processes. The cells in a multicellular organism play a critical role in the homeostasis of the organism as a whole. Parts of the human body are continuous with the external environment. External environments: continuous with the outside world: Homeostasis= the ability of the body to maintain a relatively constant internal environment. Normal blood glucose: 4-6 mol/l before a meal. Dynamic, self-regulatory process involving all organs, tissues and cells of the body. To maintain, body needs to be able to detect and respond to changes in its internal environment to keep it an acceptable range. Have feedback loops- can be positive or negative.
