|
|
Subdivisions of the thoracic cavity that contain the lungs
|
Pleural cavities
|
|
The central tissue mass that divides the thoracic cavity into two pleural cavities; includes the aorta and other great vessels, the esophagus, trachea, thymus, the peridcardial cavity and heart, and a host of nerves, small vessels, and lymphatic vessels
|
Mediastinum
|
|
The space between the parietal pericardium and the epicardium that covers the outter surface of the heart

|
Groups of organs that function together in a coordinated manner
|
Organ system
|
|
The study of the functions of the human body
|
Human physiology
|
|
Results from the activities of the nervous system or endocrine system, two organ systems that control or adject the activities of many other systerms simultaneously
|
Extrinsic regulation
|
|
A sensor that is sensitive to a particular environmental change or stimulus
|
Receptor
|
|
Recieves and processes the information supplied by the receptor and sends out commands
|
Control center
|
|
This exists when opposing preocesses or forces are in balance

Transverse plance
|
|
An imaging technique that used X ray sto reconstruct the body's three-dimensional structure

CT Scan
|
|
A malfunction of organs or organ systems resluting from a failure of homeostatic regulation
|
Disease
|
|
A technique used to monitor blood flow through specific organs, usch as the brain, heart, lungs, or kindeys. X rays are taken before and after a radiopaque dye is administered and a computer "subtracts" details common to both images. The result is a high-contrast image shoing the distribution of the dye
|

spiral-CT
|
|
An imaging techinque that uses brief bursts of high-frequency sound waves reflected by internal structures
