25
systems
related organs that have a common function
26
metabolism
sum of all chemical processes in the body
27
catabolism
the breakdown of complex chemical substances into similar components; decomposition
28
anabolism
the building up of complex chemical substances from smaller, simpler components; synthesis
29
responsiveness
detect and respond to environmental changes
30
stimulus
disruption that changes a controlled condition
31
receptor
monitors changes in a controlled environment, sends input (nerve impulses, chemical signals) to a control center
32
control center
sets a range of values, evaluates input received from receptors, generates output commands
33
effector
receives output from control center, produces a response or effect, changes the controlled condition
34
negative feedback loop
a response reverses the original stimulus
35
anatomy
science of body structures and the relationships among them
36
dissection
the careful cutting apart of body structures to study their relationships
37
physiology
the science of body functions - how the body parts work
38
epithelial tissue
covers body surfaces, lines hollow organs and cavities, and forms glands
39
connective tissue
connects, supports ,and protects body organs while distributing blood vessels to other tissues
40
muscular tissue
contracts to make body parts move and in the process generates heat
41
nervous tissue
carries information from one part of the body to another through nerve impulses
42
inspection
the examiner observes the body for any changes that deviate from normal
43
growth
an increase in body size that results from an increase in the size of existing cells, an increase in the number of cells, or both
44
differentiation
the development of a cell from an unspecialized to a specialized state
45
stem cells
precursor cells which can divide and give rise to cells that undergo differentiation
46
reproduction
the formation of new cells for tissue growth, repair, or replacement; the production of a new individual
47
feedback loop
a cycle of events in which the status of a body condition is monitored, evaluated, changed, re-monitored, reevaluated, and so on
48
stimulus
any disruption that changes a controlled condition
49
controlled condition
monitored variables such as temperature, blood pressure, or blood glucose level
50
afferent pathway
the pathway that the receptor uses to send information to the control center
51
efferent pathway
the pathway for output from the control center
52
positive feedback loop
strengthens or reinforces a change in one of the body's controlled conditions
53
disorder
any abnormality of structure or function
54
disease
a more specific term for an illness characterized by a recognizable set of signs and symptoms; alters body structures and functions in characteristic ways
55
local disease
affects one part or a limited region of the body
56
systemic disease
affects either the entire body or several parts of it
57
symptoms
subjective changes in body functions that are not apparent to an observer ex.) headache, nausea, anxiety
58
signs
objective changes that a health care professional can observe or measure can be either anatomical or physiological
59
epidemiology
the science that deals with why, when, and where diseases occur and how they are transmitted among individuals in a community
60
pharmacology
the science that deals with the effects and uses of drugs in the treatment of disease
61
diagnosis
the science and skill of distinguishing one disorder or disease from another
62
aging
a normal process characterized by a progressive decline in the body's ability to restore homeostasis
63
medical imaging
techniques and procedures used to create images of the human body
