What is Physiology? Physiology is the study of life processes How living systems work at many levels: Molecular level Organ and systems levels Whole organism level How living systems respond to physical activity How living systems respond to environmental conditions How the genome translates into function at different levels
Why is Physiology Important? Physiology expands our Understanding of… What life is How life processes work and are regulated Diseases and how to treat them How living organisms cope with or adapt to different environments
What Do Physiologists Study? Plants Vertebrates, such as: Humans and other mammals Birds Reptiles Amphibians Fish Invertebrates, such as: Insects Worms Mollusks
What Do Physiologists Study? Physiologists follow the ABC rules for use of living organisms: Appropriate Beneficial Caring
What Kinds of Questions Do Physiologists Ask? Example: How do mutations in genes affect cellular, organ and bodily function in health and disease? Tools, Techniques and Models: Use molecular biology techniques to study DNA, RNA, and cell proteins in cells in culture Measure organ function in rat and mouse strains with single gene mutations or gene knock-outs
What Kinds of Questions Do Physiologists Ask? Example: Can exercise decrease the loss of calcium from the bones that occurs when a person is exposed to microgravity (space)? Tools, Techniques and Models: Use a specialized X-ray machine to measure bone density before and after space flight in those who did and did not exercise on a treadmill while in microgravity.
What Kinds of Questions Do Physiologists Ask? Tools, Techniques and Models: Use heart cells isolated from normal rats and rats with diabetes Use electrophysiological, biochemical, pharmacological, and molecular biology techniques to study why diabetic heart cells work differently than normal heart cells Example: Why do some persons with diabetes have depressed heart pump function?
