What is physiology? - ✔️✔️- the study of the normal functioning of a living organism and its component
parts, including chemical and physical processes
- "knowledge of nature"
What are emergent properties? - ✔️✔️properties of a complex system that cannot be explained by a
knowledge of a systems individual components
What do emergent properties result from? - ✔️✔️from complex, nonlinear interactions of the systems
different components
What are some examples of emergent properties? - ✔️✔️- emotion or intelligence in humans cannot be
predicted from knowing the individual properties of nerve cells
- the human genome project (pg 2 in textbokk)
What are the levels of organization? - ✔️✔️Chemistry, Molecular biology, Cell Biology, Physiology, Ecology
What are cells? - ✔️✔️smallest unit of structure capable of carrying out life processes
What are tissues? - ✔️✔️Collection of cells carrying out related functions
what are organs? - ✔️✔️formation of tissues into a structural and functional unit
What are organ systems? - ✔️✔️integrated groups of organs
What is the function or "why" approach? - ✔️✔️is considered a teleological approach
What is the mechanism or "how" approach? - ✔️✔️- considered a mechanism approach
, - ex. oxygen binds to hemoglobin molecules in the red blood cells
does Physiology focus on mechanism or teleological approach? - ✔️✔️mechanism
what is homeostasis? - ✔️✔️the ability to maintain and relatively stable internal environment in spite of
exposure to external variability
what are variables in body that maintain homeostasis? - ✔️✔️blood pressure, bodytemp, ion/molecule
concentration, gas partial pressures, etc.
T or F - homeostasis and regulation of the internal environment are key principles in physiology? -
✔️✔️True
What are some examples of external change? - ✔️✔️- toxic chemicals
- physical trauma
- foreign invaders (bacteria or viruses)
what are some examples of internal change? - ✔️✔️- abnormal cell growth
- autoimmune disorders
- genetic disorders
what is important for the internal environment of the body? - ✔️✔️- constancy (most cells are not
tolerant to changes in their surroundings)
- Extracellular fluid (ECF)
- Dynamic steady state (materials constantly moving back and forth)
what is extracellular fluid (ECF)? - ✔️✔️surrounding cells and is a buffer between cells and external
environment
