 Mouth gag having three dimensional alveolus retractor adjustability - Patent 4024859
1 is a front elevational view of the mouth gag embodying the invention showing the alveolus retractors in a substantially normal fully extended symmetrical position and the tongue retractor positioned midway between the upper jaw engaging members of the alveolus retractors and the base support.
Alveolus retractors 30, except for being mirror images of each other, are structurally indentical so that a description of either side applies to the other and corresponding parts are given the same reference numerals.
Alveolus retractor 30 is seen to comprise a tubular post 35, an arcuate bar 31 extending from the upper end of post 35, and an upper jaw engaging member 32, which is mounted for limited sliding movement on bar 31 between projecting screw heads 31a serving as stops therefor.

 Howstuffworks "Is it harmful to breathe 100-percent oxygen?"
Surrounding each alveolus are small, thin-walled blood vessels lined with a single layer of epithelial cells called pulmonary capillaries (pulmonary because they are found in the lung).
Between the capillaries and the alveolus is a thin wall (about 0.5 microns thick) through which various gases (oxygen, carbon dioxide, nitrogen) can exchange between the air space of the alveolus and the blood in the capillary.
Because the oxygen concentration is high in the air and low in the blood entering the pulmonary capillary, oxygen flows or diffuses from the air into the blood.

 Dental implant and method of inserting - Patent 4220712
Between the spheric head pin and the alveolus an elastic covering is provided and is capable of being deformed in order to allow springing and slight oscillations of the spheric head pin with respect to the alveolus.
On the basis of the foregoing experience, according to the present invention, an apparatus was designed that includes an artificial spheric alveolus for a pin supporting the tooth or prosthesis, with the object of protecting the jaw bone and the gum where the dental implants is in communication with the oral cavity.
Thus, the alveolus 3 will be provided in the central and lower part of the lower portion 2 with a spheric projection that will act as an intermediate support in order to reduce the unit load acting on the bore.

Oxygen is inhaled and absorbed into the bloodstream through the thin walls of each alveolus, by way of the pulmonary veins.
The enormous surface area of the alveoli and the short diffusion distance between alveolar air and capillary blood quickly allows the blood to achieve an equilibrium with gases of the alveolar air.
This function is further increased by the fact that each alveolus is surrounded by a capillary network so extensive that it forms an almost continuous sheet of blood around each alveolus.

In each alveolus 10 microscopic fields were analyzed with the use of a grid developed by Merz and Schenk (1970).
Knowing the area covered by the grid, it was possible to estimate the volumetric density of bone and connective tissue and of the implanted materials in the alveolus by counting the points on these structures (1000 per alveolus analyzed, corresponding to 10 microscopic fields times 100 grid points).

Despite the same pressure gradient at the alveolus, the theoretical considerations of connected bubbles and the necessary normal variation in alveolar size, the alveoli will all inflate with full inspiration.
Micrographs show that pulmonary surfactant is primarily a monolayer in the alveolus, separating the minimal water phase from the air and lying almost adjacent to the surface of cells.
The lining cells of the alveolus are, in the main, either thin structures, type I cells, or bulky type II cells with lots of intracellular tools (mitochondria, granules and lamellar bodies) for making, storing and secreting things.

Each alveolus has many cleaning cells called macrophages that eat up any particles that made it down to the alveoli.
In trying to eat this particle the macrophage essentially cuts itself open, and the digestive molecules that were contained inside the macrophage have now spilled on the alveolus.
These molecules injure the alveolus and cause it to form a scar.

CHARLOTTE — Alveolus has received regulatory clearance in the United States and European Union for what it calls the world's first removable non-vascular self-expanding metallic stent.
Because it can be removed, physicians can use the Alveolus stent to apply temporary and minimally invasive treatments for patients with benign lumenal strictures, which the company says eliminates any concerns and complications associated with permanent implants.
Alveolus, in collaboration with its medical advisory board, says it was able to develop this new stent technology platform to meet the needs of physicians and their patients.

After oxygenation blood moves into the pulmonary veins which return to the left side of the heart to be pumped to the systemic tissues.
In a 'perfect lung' the PO of pulmonary venous blood would be equal to the PO in the alveolus.
Oxygen diffuses from the alveolus to the capillary until the PO in the capillary is equal to that in the alveolus.
