| | * Alveoli - (Disease): Definition |
 | | Atelectasis is the medical term for collapse of areas of the alveoli in the lungs. | | | As a result, the chest and diaphragm are stretched and distended as if taking a deep breath, even when the person is exhaling... | | | When the alveoli don't work efficiently, your lungs have to work harder to satisfy your body's need for oxygen. |

| | Product having alveoli, semi-finished product therefor and method of making the products - Patent 5171621 |
| | Finally, although the invention has been described with reference to particular means, materials and embodiments, it is to be understood that the invention is not limited to the particular disclosed and extends to all equivalents within the scope of the claims. | | | According to a particular aspect of the present invention, the step of creating each of the rough alveoli comprises creating respective contours of each of the rough alveoli to be substantially identical. | | | According to a still further aspect of the present invention, the step of creating each of the rough alveoli comprises creating respective contours to be circular and creating respective bottoms to have the shape of a substantially spherical segment centered on the axis. |

| | The lower respiratory passages are comprised of the trachea, bronchial system, and the alveoli. | | | Due to these collapse tendencies, the lungs attempt to pull away from the chest wall and diaphragm. | | | The stretched elastic fibers attempt to contract to a relaxed situation and in doing so generate a force to collapse the lungs. |

| | The luminal diameter of a branch is related to the number of alveoli at the end of that branch (axial and lateral pathways). | | | Surfactant reduces the surface tension in the lung, equalizing pressures, stabilizing and maintaining all the alveoli in an open position despite the variation in alveolar size. | | | Bronchopneumonia can be so extensive and confluent as to overlap with lobar pneumonia. |

| | Both of these would represent serious problems: if alveoli collapsed they'd contain no air and no oxygen to diffuse into the blood and, if 're-expansion' was more difficult, inhalation would be very, very difficult if not impossible. | | | During expiration, the respiration muscles relax and lung volume descreases. | | | The expansion of the lungs causes the pressure in the lungs (and alveoli) to become slightly negative relative to atmospheric pressure. |

| | Understanding the implications of the Law of LaPlace is important because alveoli in the lungs and the lungs as a whole behave as these balloons do. | | | The other is that the surface tension of the alveoli can be altered by the processes that occur within them. | | | One is the fact that the alveoli (lungs) do not deflate completely during exhalation. |

| | Blood and macrophages collect in alveoli, with hemosiderin accumulation in the macrophages from breakdown of blood. | | | The conducting passageways of the respiratory system (nasal cavity, trachea, bronchi and bronchioles) are lined by pseudostratified columnar epithelial tissue, which is ciliated and which includes mucus-secreting goblet cells. | | | The edges of alveolar walls which form the entry-ways into respiratory sacs and alveoli contain small bundles of smooth muscle which allow some control of air distribution among various regions of the lung. |

| | Tennis racket having alveoli filled honeycomb reinforcement - Patent 4505480 |
| | Starting from this observation, applicant has derived a simple means for influencing, in any desired manner, the equilibrium or the transverse inertia moment of the racket. | | | The various construction systems briefly described above have a common point in that, during their manufacture, it is possible to determine with a relatively large accuracy the final position of each of the alveoli of the honeycomb in the finished frame. | | | In a co-pending Belgian patent application filed herewith, applicant describes a tubular means reinforced with a honeycomb, having particularly interesting mechanical properties in a large number of applications, namely the manufacture of racket frames. |

| | By lowering the surface tension and compression surfactant becomes an important advantage to the physiological function or mechanics of the lung. | | | Surfactant is important physiologically as well as to the course since lung mechanics depends a lot on the substance and a deficiency of it can result in the stiffening of the lung and causes Respiratory Distress Syndrome. | | | Anitha Mittapalli BME 403 SURFACTANT A Surfactant(wetting agent or detergent) is a substance which lowers the surface tension of water, especially of the alveolar lining fluid within the lung and is physiologically advantageous to the lung in various respects. |

| | ARDS - Index - PulmonologyChannel |
| | ARDS requires treatment with mechanical ventilation or some other form of assisted breathing. | | | A variety of underlying conditions, from blood-borne infections to major trauma, can cause the characteristic inflammation and accumulation of fluid (edema) in the alveoli (see causes). | | | If the original injury is in the alveolar capillaries that lie just beneath the alveoli, chemical mediators (usually cytokines) that the immune system releases in response, rush to the site of the injury, damaging and causing inflammation to the cells that line the capillaries (i.e., the capillary endothelium). |

| | Respiratory Research Abstract Leukocyte trafficking in alveoli and airway passages |
| | Although the mechanisms are often particular to each disease process, site-specific differences in leukocyte trafficking and the regulation of inflammation also occur. | | | Many pulmonary diseases preferentially affect the large airways or the alveoli. | | | The presence of different cell types in large airways from those in alveoli might contribute to site-specific differences in the molecular regulation of the inflammatory process. |

| | Alveoli History - Alveoli Information |
| | Carbon dioxide circulates through the body in the blood, until it reaches the alveolar capillaries. | | | It is interesting to note that, when comparing the alveoli of various species, the alveoli change in terms of both size and quantity. | | | Carbon dioxide crosses out of the capillaries into the alveoli at the same time that oxygen is crossing out of the alveoli and into the capillaries. |

| | In this way, oxygen seeps through into the bloodstream and carbon dioxide, in the bloodstream, seeps through into the alveoli, and is then removed from the body when we breathe out. | | | The walls are so thin and close to each other that the air easily seeps through. | | | Capillaries, which are small blood vessels with thin walls, are wrapped around these alveoli. |
