Flashcards in Ch. 1:Intro To Physiology Deck (27):
1

How are functions initiated in controlled

Physical events -contraction of the heart and skeletal muscle
chemical events-Energy for contraction

2

What is the difference between anatomy and physiology

Anatomy is what is this in physiology is how does it work

3

What are some organ systems of the body

Integumentary System
Nervous system
endocrine system
skeletal system
Muscular System
Circulatory system
Immune system
Respiratory system

4

What are the levels of organization in order from smallest to largest

Chemical
cellular
tissue
organ
system
organism

5

What happens in the organism level

Proper function of the organism is dependent upon the function of individual systems

6

What happens in the system level

Collection of organs that work together to perform various tasks

7

What happens in the organ level

Two or more types of tissues working together to perform various tasks

8

What is a tissue

Functional grouping (aggregation) of cells

9

What are four primary types of tissues

Muscle
nervous
Epithelial tissue
Connective tissue

10

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

11

What is an Atom

Smallest building blocks
Oxygen, carbon, nitrogen, and hydrogen

12

Atoms combined to form _________

Molecules
Some examples are carbohydrates, fat, proteins, nucleic acids

13

What are molecules

The raw ingredients that are used to form a cell and allow it to function

14

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

15

What is an example of functions that each system controls

CVS delivery of blood to cells throughout the body

16

What is example of how functions are initiated and controlled

Specialized cells in the heart initiate contraction of the heart

17

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

18

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

19

Cardiovascular and respiratory systems work together to deliver __________and eliminate __________?

oxygen; carbon dioxide

20

The heart is ______ dependent on the nervous system but it is influenced and integrated in the physiological system

Not

21

The nervous system in musculoskeletal system work together to produce _______?

Movement

22

Skeletal muscle contraction is dependent on _________?

Nervous system

23

What is integration of physiological systems

Optimal function of the organism is dependent on the integration of ALL physiological systems

24

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

25

What is a disease

A disorder of structure or function of the human body produces specific signs or symptoms

26

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

27

What is human physiology?

A biological function of the human body
Determines how functions are initiated and controlled
Inseparable from anatomy
