Textbook Citation: 
​Sherwood, Lauralee, et al. “Chapter 1: Homeostasis and Integration: The  Foundations of Physiology.”  Animal Physiology: From Genes to Organisms ​, 2nd ed.,  Brooks/Cole, 2005, pp. 1–23. 
 
Chapter 1: Homeostasis and Integration: The Foundations of Physiology (Continued) 
● 1.5: Homeostasis: Basic Mechanisms and Enhancements  ○ Key people to note:  ■ Claude Bernard: documented ability of mammals to maintain a relatively  constant internal environment  ■ Walter B. Cannon: coined the term, “homeostasis”  ○ Homeostasis ​: maintenance of constant internal state, this is a dynamic steady  steady state  ○ Majority of cells in multicellular organism are not in direct contact with the  external environment  ○ Internal environment ​ consists of ​extracellular fluid  ■ Plasma 
■ Interstitial fluid 
○ Homeostasis is essential for proper cell function  
○ Homeostatically regulated factors: 
■ Concentration of energy rich molecules 
■ Concentration of O
2  and CO ■ Concentration of waste products 
■ pH 
■ Concentration of water, salt, and other electrolytes 
■ Volume and pressure 
■ Temperature 
■ Social parameters 
○ Animals vary in homeostatic abilities   ■ Regulators ​: use internal mechanisms to defend relatively constant state  ■ Conformers ​: internal state varies with the environment  
background image ■ Avoiders ​: minimize internal variations by avoiding environmental  disturbances  ○ Negative feedback ​ is the main regulatory mechanism for homeostasis  ■ Occurs when change in a controlled variable triggers a response that  opposes   a change  ■ A negative feedback system is comprised of  ● Sensor ​: measures variable being regulated  ● Integrator ​: compares sensed info with a set point  ● Effector ​: makes the corrective response  ○ Ex. room temperature control, mammalian  thermoregulation  ● 1.6: Regulated Change  ○ Some internal processes are not always homeostatic  ■ Dormancy 
■ Locomotion 
■ Growth/development 
■ Neural signalling  
■ On demand regulation (ex. digestion) 
■ Reset systems (change the set point) 
■ Positive feedback systems 
○ Positive feedback ​ system  ■ Output is continually enhanced so the controlled variable continues in the  direction of the initial change  ● Creates  ​rapid change  ● Ex. oxytocin release and uterine contractions during birth  ○ Disruption in regulation leads to illness or death  ■ Pathophysiology ​: altered physiology of organisms associated with disease  ● Ex. congestive heart failure is a positive feedback cycle leading to  death  ● 1.7: Organization of Regulatory and Organ Systems  ○ Homeostasis is hierarchically distributed  ■ Regulated at the cellular level 
■ Intrinsic control
​: regulated by ​tissue​ or ​organ​ for its own benefit 
background image ■ Extrinsic control ​: regulation mechanisms initiated ​outside​ an organ to alter  activity  ● Coordinated regulation of  ​several organs​ toward common goal  ○ Organ Systems  ■ Whole Body Systems:  ● Endocrine → takes longer, lasts longer 
● Nervous → more instantaneous 
■ Support/Movement Systems  ● Skeletal 
● Muscle 
■ Maintenance Systems  ● Circulatory 
● Immune 
● Respiratory  
● Excretory 
● Digestive 
● Integumentary 
■ Reproductive System
