Physio - Ch. 1 Flashcards
Properties that cannot be determined by looking at the individual parts of the whole
Emergent properties
What is the difference between “Function” and “Mechanism”?
“Function” refers to the ‘why’
-Why do the cells need this?
“Mechanism” refers to the “how”
-How do cells acquire this from the blood?
Which approach will we take when referring to “Function”?
Or, which approach answers “why”?
Teleological Approach
“Explanation of something in the ‘why’ sense
Which approach answers “how”?
Mechanistic Approach
Which theme of physiology describes how the shape of molecules defines their function, and any changes to the shape alters their function?
“Structure and Function are closely related”
Which term describes the “division of space” and how cells/tissues are able to isolate and specialize?
Compartmentation
Which theme of physiology describes how and where organisms retrieve energy?
Living organisms need energy
Which theme of physiology describes information flow/cell communication?
Information flow coordinates body function
Which theme of physiology describes homeostasis and negative feedback?
Homeostasis maintains internal stability
This term is defined as “maintaining a stable internal environment”
Homeostasis
This serves as a transitory point in the body between the external environment and ICF. This is also often how homeostasis is examined
Extracellular Fluid
This law is described as:
“If the amount of substance inside the body is to be maintained, any gain must be offset by an equal loss”
Law of mass balance
AKA the body’s “load”
This equation corresponds with which law?
Mass Balance = Existing body load + Intake - Excretion
Law of mass balance
What is the equation used to determine mass flow?
(amount X/volume) / (volume/min)
Or:
[X] x Volume Flow
What term is described as:
“Rate of substance leaving the blood”?
Clearance
