Lesson 1B. Physiology Continuation and the Levels of Structural Organization Flashcards
the science of studying the functional activities and their mechanisms in the biological body
Physiology
meaning of Greek -physis
nature
meaning of Greek logos
study
History of Physiology
He emphasized the relationship between structure and function
Aristotle
History of Physiology
- He was the first to perform experiments to understand the
function of the body - “Father of Physiology”
Galen
History of Physiology
- First “Physiologist” of the world, in the modern sense
- First described the circulatory system and its interaction with the body
William Harvey
HIstory of Physiology
- French Physiologist who propounded the concept of milieu interieur or internal environment and established physiology as the scientific basis of medicine.
- “Father of Modern Physiology”
Claude Bernard
Answers the question “How”
* How do we breathe?
* How does blood flow?
Process
Answers the question “Why”
* Why do we breathe?
* Why does blood flow?
Function
Resulting from a pathophysiological response to external or internal factors.
Disease
Ex: Cardiovascular disease
A disruption of the disease to normal or regular functions in the body or a part of the body.
Disorder
Ex. Arrythmia (abnormal heart beat)
- Refers to a disease or a disorder that has more than one identifying feature or symptom.
- A collection or set of signs and symptoms that characterize or suggest a particular disease.
Syndrome
Ex. Down Syndrome
An abnormal state of health that interferes with the usual activities or feeling of well-being.
Condition
Ex: chronic fatigue syndrome is a neurological condition
- Subjective
- Feelings and concerns that you feel
- Perceived only by the person who is experiencing
- them.
Symptoms
Ex: Shortness of breath
- Objective
- Something that others can observe or measure
- Can be detected by various tools (stethoscope, x-rays, lab tests)
Signs
Ex: Wheezing
Enumerate the Levels of Structural Organization
- Chemical
- Cellular
- Tissue
- Organ
- System
- Organismal
Body system that takes in nutrients, breaks them down, and eliminates unabsorbed matter (feces)
Digestive System
Body system that takes in oxygen and eliminates carbon dioxide
Respiratory System
Body system that distributes oxygen and nutrients to the body cells via blood and delivers wastes and CO2 to disposal organs
Cardiovascular System
Body system that eliminates nitrogenous wastes and excess ions
Urinary System
Nutrients and wastes pass between blood and cells via the ___.
Interstitial Fluid
Body system that protects the body as a whole from the external environment
Integumentary System
Necessary life function that keeps internal environment distinct from the external environment
Maintain boundaries
