ANSC 3301 Lecture 7: 23 January-2
Document Summary
How living systems respond to physical activity. How living systems respond to environmental conditions. Function and integration of biological systems at all major levels of organization. Understanding basic mechanisms that underlie the function and integration of biological systems. Physiology: study of life processes and how living organisms work. How living systems work at many levels. Five papers that described experiments that wanted to determine the laws that govern the movement of ions in a nerve cell during an action potential. Achieving homeostasis requires various component physiological systems to function coordinately. Claude bernard- french physiologist who developed the concept of the internal milieu (describes extracellular fluid that surrounds cells) Recognized many animals regulate their internal environment even if the external environment changes. Constancy of the internal environment is the condition for free life . Walter cannon- coined the term homeostasis in 1926. Realized the importance of the ans in maintaining a relatively constant internal environment.
