Pathophysiology
the very basic level which includes atoms, the smallest units of matter that participate in chemical reactions, and molecules, two or more atoms joined together
Chemical level
molecules combine to form cells, the basic structural and functional units of an organism that are composed of chemicals
Cellular level
groups of cells and the materials surrounding them that work together to perform a particular function
Tissue level
different types of tissues are joined together that have specific functions and usually have recognizable shapes
Organ level
consists of related organs with a common function
System level
any living individual; all the parts of the human body functioning together constitute the total organism
Organismal level
Level Of Structural organization (7 steps)
Atom - Molecule - Cell - Tissue - Organ - Organ System - Organism
sum of all chemical processes that occur in the body
Metabolism
types of chemical processes that occur in the body (2pts)
Catabolism and Anabolism
body’s ability to detect and respond to changes
Responsiveness
motion of the whole body, individual organs, single cells, and even tiny structures inside cells
Movement
increase in body size that results from an increase in the size of existing cells, an increase in the number of cells, or both
Growth
development of a cell from an unspecialized to a specialized state
Differentiation
refers either to the formation of new cells for tissue growth, repair or replacement, or the production of a new individual
Reproduction
is the maintenance of relatively stable conditions in the body’s internal environment
Homeostasis
Occurs because of the ceaseless interplay of the body’s regulatory systems, and is a dynamic condition
Homeostasis
An important aspect of _______________ is maintaining the volume and composition of body fluids
Homeostasis
The body can regulate its internal environment through what ?
Many feedback systems
It is a cycle of events in which the status of a body condition is monitored, evaluated, changed, remonitored, re-evaluated, and so on
Feedback System
what do you call a monitored variable?
controlled condition
any disruption that changes a controlled condition
Stimulus
monitors changes in a controlled condition and sends input to a control center
Receptor
sets the narrow range or set point within which a controlled condition should be maintained
Control Center
receives output from the control center and produces a response or effect that changes the controlled condition
Effector
Reverses a change in a controlled condition
Negative Feedback System
Strengthens or reinforces change in a controlled condition
Positive Feedback System
Failure of the human body to maintain the physiological processes
Homeostatic Imbalances
an abnormality of structure of function results to what?
Disorder
is a more specific term for an illness characterized by a recognizable set of signs and symptoms
Disease
subjective changes in a body part of function
Symptoms
objective changes observable by clinicians
Signs
standard position of reference when describing any region or part of the human body
Anatomical position
body is lying facedown/on belly
Prone
body is lying faceup/on back
Supine
the body is lain supine, or flat on the back on a 15–30 degree incline with the feet elevated above the head.
