A small cavity in a coral, shell, or fossil
A small depression, sac, or vesicle, as the socket of a tooth, the air cells of the lungs, the ultimate saccules of glands, etc.
a small hollow or cavity; an air sac in the lungs; milk-secreting portion of a mammary gland
a small cavity, e.g., in the lungs.
Tiny sac-like space; pulmonary alveoli are tiny sac-like spaces in the lung where gas exchange between oxygen and carbon dioxide takes place.
A socket in which the root of a tooth is set.
(al ve´ o lus) (plural: alveoli) [L. alveus: cavity] • A small, baglike cavity, especially the blind sacs of the lung.
Termination of the airways in the lungs; primary site of gas exchange with the blood.
a tiny sac for holding air in the lungs; formed by the terminal dilation of tiny air passageways
a bony socket in the alveolar ridge that holds a tooth
a lung air sac where gas exchange with the blood occurs
a tiny airsac in the lung
(plural alveoli): Thin-walled air sac in the lung which permits gas exchange.
small cavity or socket (usually in lung where oxygen and carbon dioxide are exchanged)
(awl-VEE-o-lus); alveoli plural form A microscopic air sac within the lungs.
A glandular acinus or the ending portion of the alveolar gland where milk is secreted and stored, 0.12 mm in diameter. From 10 to 100 alveoli, (tubulosaccular secretory units), make up a lobulus; a group of milk producing cells.
air sac where gas exchange takes place.
Socket in jawbone that receives root(s) of tooth or contains base of ever-growing tooth.
Latin a basin, hence any small hollow. Plural - alveoli, adjective - alveolar.
The tiny sacs in the lung where oxygen and carbon dioxide are exchanged by red blood cells. Alveoli are the terminations of the bronchial tubes; each sac is about .25 mm in size and there are approximately 1.5 million in each lung.
The part of the jawbone that supports the teeth.
One of the network of tiny spaces in the lung; the site where oxygen is presented to the blood and waste gases are removed for exhalation.
1. Microscopic sac in the lung 2. Spherical sac
(al-VEE-uh-liss) Alveoli (plural of alveolus, pronounced al-VEE-uh-lie) are tiny thin-walled air sacs that are found in large numbers in the lungs, through which oxygen enters and carbon dioxide leaves the blood. Also called acinus or air sac. diagram
Small air sac of the lungs.
Sac-like structure of the lung where oxygen exchange occurs. Alveoli is pleural.
A small sac-like structure in the body, especially common in the lung. A lung alveolus has extremely thin walls that aid in the exchange of gases including O2 and CO2.
The smallest unit of the lung that is responsible for exchanging oxygen for carbon dioxide and other gases.
Blind pockets at the end of the respiratory tree, lined by a simple squamous epithelium and surrounded by a capillary network; sites of gas exchange with the blood; a bony socket that holds the root of a tooth.
Thin-walled, air-filled "outpocketing" from terminal air passageways in lungs; cell cluster at end of duct in secretory gland.
