Alveolus
|
|
Alveolus" One of the tiny air sacs located at the very ends of the bronchioles within the lungs where the exchange of oxygen and carbon dioxide takes place. The alveolus looks like a cell in a honeycomb. The word comes from the Latin diminutive of ""alveus"" meaning a cavity or hollow = a little cavity or hollow. The plural of alveolus is alveoli and the adjective is alveolar."
RELATED TERMS--------------------------------------
Lungs
The main respiratory organs in the chest where blood is oxygenated.
Oxygen
A chemical element essential for sustaining life.

Cell
Fundamental structural unit of all life. The cell consists primarily of an outer plasma membrane, which separates it from the environment; the genetic material (DNA), which encodes heritable information for the maintainance of life; and the cytoplasm, a heterogeneous assemblage of ions, molecules, and fluid.
Cavity
A hollow place or hole within the body.
Alveoli
The sacs in the lungs at the ends of the smallest airways where oxygen is exchanged for carbon dioxide in the blood.
SIMILAR TERMS--------------------------------------
Alveolar
"Pertaining to the alveoli, the tiny air sacs in the lungs. The exchange of oxygen and carbon dioxide takes place in the alveoli which look like cells in a honeycomb. The word comes from the Latin diminutive of ""alveus"" meaning a cavity or hollow = a little cavity or hollow."
Alveolar bone
The jaw bone that anchors the roots of teeth.
Alveolar hydatid disease
"Abbreviated AHD. A parasitic disease caused by the larval stage of a microscopic tapeworm Echinococcus multilocularis. AHD is found worldwide, mostly in northern latitudes. in central Europe, Russia, China, Central Asia, Japan, and North America. In North America E. multilocularis is found primarily in the north central region from eastern Montana to central Ohio, as well as in Alaska and Canada. Human cases have been reported in Alaska, the province of Manitoba, and Minnesota. Prevalence among wild foxes and coyotes is high, and may reach over 50% in some areas; however, even in these areas, transmission to humans has been low. Wild foxes, coyotes, and cats get infected when they eat Echinococcus multilocularis larvae in infected rodents, field mice, or voles. Cats are less susceptible than dogs, but because they probably catch and eat rodents more often, may also become infected. Once the animal becomes infected, the tapeworm matures in its intestine, lays eggs, and the infected animal passes eggs in the stool. These tapeworm eggs, which are directly infectious to other animals, are too tiny to see, and will stick to anything with which they come in contact. Coyotes, foxes, dogs, and cats are not harmed by the tapeworm and do not have symptoms of AHD.
Alveolar proteinosis

Alveoli

Alveolitis
Inflammation of the alveoli, the air sacs in the lungs.

Amastia
A rare condition wherein the normal growth of the breast or nipple does not occur. Unilateral amastia (just on one side) is often associated with absence of the pectoral muscles. Bilateral amastia (with absence of both breasts) is associated in 40% of cases with multiple congenital anomalies (birth defects) involving other parts of the body as well.
Amathophobia
An abnormal and persistent fear of dust. Sufferers experience anxiety even though they realize dust poses no threat.
Amaurosis fugax
"A symptom described as a shade coming down over the eye. A partial or complete loss of sight that is temporary.
