Physiology 2130 Lecture Notes - Lecture 4: Body Fluid, Endocrine System, Extracellular Fluid
Document Summary
By the end of this section, you should be able to . List the levels of organization in the human body. Essentially, the problem faced by the body and all of its cells is how to surround themselves with barriers that allow desired substances to pass in and waste to pass out while maintaining their own internal environment. Physiology is the study of function in living organisms. It explores the mechanisms by which the organisms control their internal environments regardless of. Physiology also attempts to explain the physical and chemical factors responsible for both normal what happens in the external environment. function and disease (also called pathology ). Essentially consists of the interstitial fluid and blood plasma (will examine more in detail in module 2) The internal environment is the fluid in which cells of our body are bathed. External environment is the region outside the body.
