Document Summary
Module 1 online notes (sec 1. 1 to 1. 11) Physiology is the study of function in living organisms. It explores the mechanisms by which organisms control their internal environment despite what is occurring in the external environment. Physiology also attempts to explain the physical and chemical factors responsible for normal function and disease (pathology) Homeostasis the maintenance of relatively stable conditions within the internal environment regardless of what is happening in the external environment. The internal environment is the fluid in which the cells of the body are bathed and consists of the interstitial fluid and blood plasma. The external environment is the region outside the body including the space and contents of the digestive, respiratory and urogenital tracts. The body maintains homeostasis using negative and positive feedback control mechanism. Found throughout the body and perform different functions, from maintaining body temperature to maintaining body fluid volumes.
