Ch. 1:Intro To Physiology Flashcards
How are functions initiated in controlled
Physical events -contraction of the heart and skeletal muscle
chemical events-Energy for contraction
What is the difference between anatomy and physiology
Anatomy is what is this in physiology is how does it work
What are some organ systems of the body
Integumentary System Nervous system endocrine system skeletal system Muscular System Circulatory system Immune system Respiratory system
What are the levels of organization in order from smallest to largest
Chemical cellular tissue organ system organism
What happens in the organism level
Proper function of the organism is dependent upon the function of individual systems
What happens in the system level
Collection of organs that work together to perform various tasks
What happens in the organ level
Two or more types of tissues working together to perform various tasks
What is a tissue
Functional grouping (aggregation) of cells
What are four primary types of tissues
Muscle
nervous
Epithelial tissue
Connective tissue
What is a cell
Basic unit of structure and function
Smallest unit capable of carrying out processes associated with life
Trillions of cells, variety of different types/sizes/shapes and abilities
What is an Atom
Smallest building blocks
Oxygen, carbon, nitrogen, and hydrogen
Atoms combined to form _________
Molecules
Some examples are carbohydrates, fat, proteins, nucleic acids
What are molecules
The raw ingredients that are used to form a cell and allow it to function
What is the difference between parasympathetic and sympathetic nervous system?
When does heart rate increase or decrease?
Parasympathetic is at rest in sympathetic is during activity
Heart rate increases during sympathetic nervous system and decreases during parasympathetic nervous system
What is an example of functions that each system controls
CVS delivery of blood to cells throughout the body
What is example of how functions are initiated and controlled
Specialized cells in the heart initiate contraction of the heart
What is it example of integration of the different organs within a system to carry out a specific function
Contraction of the heart influences blood vessels and blood vessels influence contraction of the heart
What is integrative physiology
Function for each system controls
How functions are initiated and controlled
Integration of different organs within the system to carry out a specific function
Integration of one or more physiological systems
Cardiovascular and respiratory systems work together to deliver __________and eliminate __________?
oxygen; carbon dioxide
The heart is ______ dependent on the nervous system but it is influenced and integrated in the physiological system
Not
The nervous system in musculoskeletal system work together to produce _______?
Movement
Skeletal muscle contraction is dependent on _________?
Nervous system
What is integration of physiological systems
Optimal function of the organism is dependent on the integration of ALL physiological systems
What is the importance of integrative physiology
- If you know how the normal bodily functions are initiated in control and how physiological systems interact with each other you will have insight into the origin of the disease/problem
- with such knowledge you will be in better position to develop/prescribed affective treatments in interventions (example drugs and rehabilitation) as well as understand the implications that such approaches have in restoring normal function
What is a disease
A disorder of structure or function of the human body produces specific signs or symptoms
As a PT what level of organization of the human body do you feel you must master to be successful
Restore structure and then function apply some modality in order to restore improve the chemical and cellular levels of the body
What is human physiology?
A biological function of the human body
Determines how functions are initiated and controlled
Inseparable from anatomy
