... (FRC) is the volume of air present in the lungs at the end of passive expiration. At FRC, the opposing elastic recoil forces of the lungs and chest wall are in equilibrium and there is no exertion by the diaphragm or other respiratory muscles. FRC is the sum of Expiratory Reserve Volume (ERV) and Residual Volume (RV) and measures approximately 2400 mL in an 80 kg, average-sized male. It cannot be estimated through spirometry, since it includes the residual volume. In order to measure RV precisely, one would need to perform a test such as nitrogen washout, helium dilution or body plethysmography. A lowered or elevated FRC is often an indication of some form of ...
In December 1960, Hubbard was invited to play on Ornette Coleman's Free Jazz after Coleman had heard him performing with Don Cherry.[3]. Then in May 1961, Hubbard played on Olé Coltrane, John Coltrane's final recording session for Atlantic Records. Together with Eric Dolphy and Art Davis, Hubbard was the only sideman who appeared on both Olé and Africa/Brass, Coltrane's first album with Impulse!. Later, in August 1961, Hubbard recorded Ready for Freddie (Blue Note), which was also his first collaboration with saxophonist Wayne Shorter. Hubbard joined Shorter later in 1961 when he replaced Lee Morgan in Art Blakey's Jazz Messengers. He played on several Blakey recordings, including Caravan, Ugetsu, Mosaic, and Free for All. In all, during the 1960s, he recorded eight studio albums as a bandleader for Blue Note, and more than two dozen as a sideman.[4] Hubbard remained with Blakey until 1966, leaving to form the first of several small groups of his own, which featured, among others, his Blue ...

The closing capacity (CC) is the volume in the lungs at which its smallest airways, the respiratory bronchioles, collapse. The alveoli lack supporting cartilage and so depend on other factors to keep them open. The closing capacity is greater than the residual volume (RV), the amount of gas that normally remains in the lungs during respiration, and specifically, after forced expiration. This is because closing capacity is equal to closing volume plus residual volume. This means that there is normally enough air within the lungs to keep these airways open throughout both inhalation and exhalation. As the lungs age, there is a gradual increase ...
Jesse and Angela "Angie" Hubbard are fictional characters and a supercouple from the ABC and The Online Network daytime drama All My Children. Jesse is portrayed by Darnell Williams and Angie is portrayed by Debbi Morgan. Jesse first appeared in Pine Valley, Pennsylvania in 1981 as the nephew of Dr. Frank Grant, who assumed custody after the death of his sister (Jesse's mother). Angie first appeared in 1982, as the daughter of a well-to-do Pine Valley couple. Shortly after Angie's first appearance on the show, they were paired with one another. Jesse and Angie were best friends to fellow supercouple Greg Nelson and Jenny Gardner. They are daytime television's first African American supercouple, and arguably the two most popular African American characters in soap opera history. Angie also appeared on Loving and The City. Along with her son Frankie Hubbard and former heiress Skye Chandler, she is one of only three individuals who have been regular characters on three ABC soap operas. Actress ...
The founder of the Roycroft Movement, Elbert Hubbard, also lived there during the turn of the twentieth century. Hubbard and his wife died on board the RMS Lusitania in 1915. One of the town's most famous landmarks, the Roycroft Inn, was converted from the Hubbards' original print shop and opened as an inn in 1905 to accommodate the influx of famous visitors attracted by Hubbard's ideas as well as the books, Mission-style furniture and metalware produced by the 500 Roycroft artisans on the South Grove Street Roycroft campus.[6] The Roycroft Campus was granted National Landmark Status in 1986. The Roycroft Inn was re-opened in June 1995 through the support of the Margaret L. Wendt Foundation.[7] The inn was completely restored and is open to the public for dining and accommodations. The Elbert Hubbard Museum on Oakwood Avenue features an extensive collection of Roycroft books and Arts & Crafts pieces. East Aurora is also the birthplace of and home to the corporate headquarters for ...

Scaling also has an effect on the performance of organisms in fluid. This is extremely important for marine mammals and other marine organisms that rely on atmospheric oxygen to survive and carry out respiration. This can affect how fast an organism can propel itself efficiently and more importantly how long it can dive, or how long and how deep an organism can stay underwater. Heart mass and lung volume are important in determining how scaling can affect metabolic function and efficiency. Aquatic mammals, like other mammals, have the same size heart proportional to their bodies. Mammals have a heart that is about 0.6% of the total body mass across the board from a small mouse to a large Blue Whale. It can be expressed as: Heart Weight = 0.006Mb1.0, where Mb is the body mass of the individual.[39] Lung volume is also ...
A person who is born and lives at sea level will develop a slightly smaller lung capacity than a person who spends their life at a high altitude. This is because the partial pressure of oxygen is lower at higher altitude which, as a result means that oxygen less readily diffuses into the bloodstream. In response to higher altitude, the body's diffusing capacity increases in order to process more air. Also, due to the lower environmental air pressure at higher altitudes, the air pressure within the breathing system must be lower in order to inhale; in order to meet this requirement, the thoracic diaphragm has a tendency to lower to a greater extent during inhalation, which in turn causes an increase in lung volume. When someone living at or near sea level travels to locations at high altitudes (e.g., the Andes; Denver, Colorado; Tibet; the Himalayas) that person can develop a ...

... is the literature written in Austria, which is mostly, but not exclusively, written in the German language. Some scholars speak about Austrian literature in a strict sense from the year 1806 on when Francis II disbanded the Holy Roman Empire and established the Austrian Empire. A more liberal definition incorporates all the literary works written on the territory of today's and historical Austria, especially when it comes to authors who wrote in German. Thus, the seven volume history of Austrian literature by the editors Herbert Zeman and Fritz Peter Knapp is titled History of the Literature in Austria. The Austrian literature must be considered in close connection with German literature in general, and the borderline between proper German literature and the Austrian one is porous, due to rich and complex cultural exchanges. There are and have been many tries to work out a complete definition of Austrian literature. Something most people can agree on is ...

  • Alveolar (distributive) dead space is the volume of air that reaches alveoli but never participates in respiration (e.g. due to underperfusion from hypoxic vasoconstriction). (teachmephysiology.com)
  • Because of the enormous number of alveoli (approximately 300 million in each human lung), the surface area of the lung is very large (75 m 2 ). (opentextbc.ca)
  • Any alveoli which is not being ventilated and yet has a blood supply becomes a shunt like in disease processes where there is lung consolidation or edema. (japractice.co.uk)
  • Together, the lungs contain approximately 2,400 kilometres (1,500 mi) of airways and 300 to 500 million alveoli. (meddic.jp)
  • causes inflammation and narrowing of the airways, while emphysema results in damage to the alveoli (tiny air sacs) in the lungs, making them much less effective at transferring oxygen from the lungs to the bloodstream. (enetmd.com)
  • They allow an assessment of the mechanical condition of the lungs, its musculature, airway resistance and the effectiveness of gas exchange at the alveolar membrane while being, for the most part, cheap, non-invasive and simple to measure. (teachmephysiology.com)
  • The thoracic gas volume (TGV or V TG ) is the absolute volume of gas in the thorax at any point in time and any level of alveolar pressure. (ersjournals.com)
  • The lower airway system consists of the larynx, the trachea, the stem bronchi, and all the airways ramifying intensively within the lungs, such as the intrapulmonary bronchi, the bronchioles, and the alveolar ducts. (academic.ru)
  • This figure demonstrates the model by Wilson and Bachofen, which illustrates how surface tension operates in the lung parenchyma consisting of flat alveolar septal walls. (comprehensivephysiology.com)
  • The amount of air that is always in the lungs and can never be expired (i.e.: the amount of air that stays in the lungs after maximum expiration). (bionity.com)
  • During exercise expiration is more active, with the internal intercostal muscles contracting to pull the ribcage inwards and downwards, the abdominals also contract which helps to push the diaphragm up with a much more rapid reduction in the volume of the chest cavity. (getrevising.co.uk)
  • The lungs are part of the lower respiratory tract that begins at the trachea and branches into the bronchi and bronchioles and which receive air breathed in via the conducting zone. (meddic.jp)
  • Moreover, a continuously increasing base of evidence associates exposure to WDs to interstitial lung disorders (ILD), such as the pulmonary fibrosis, and in particular the idiopathic pulmonary fibrosis (IPF) [5- (thefreelibrary.com)
  • Its definition requires the exclusion of other forms of the ILD associated with environmental exposure, medication or systemic disease, the presence of a pattern of the usual interstitial pneumonia (UIP) on high resolution computer tomography (HRCT) in patients not subjected to surgical lung biopsy and/or specific combination of the HRCT and surgical lung biopsy pattern in patients subjected to surgical lung biopsy [8, (thefreelibrary.com)
  • ABSTRACT Objective: To assess clinical utility of serum Clara cell 16-kDa protein measurements in relation with staging system for systemic sclerosis associated interstitial lung disease. (bvsalud.org)
  • Materials and methods: Serum levels of Clara cell 16-kDa protein were determined by ELISA in 28 systemic sclerosis patients and 30 healthy controls, and correlated with staging system for systemic sclerosis associated interstitial lung disease in systemic sclerosis patients. (bvsalud.org)
  • Conclusions: Clara cell 16-kDa protein levels can be considered as a supplemental serum biomarker for systemic sclerosis associated interstitial lung disease. (bvsalud.org)
  • Pathophysiology-the characteristic finding in COPD is a decrease in maximum expiratory flow, which can be reduced by two factors-(1) loss of lung elasticity, and (2) an increase in airways resistance in small and/or large airways. (enetmd.com)
  • The human gas exchanging organ, the lung, is located in the thorax, where its delicate tissues are protected by the bony and muscular thoracic cage. (academic.ru)
  • Normal lung physiology is unfortunately extremely complex, and this complexity is further enhanced in sick lungs! (anaesthetist.com)
  • Lacking smart and well-programmed supercomputers to simulate normal lung physiology, we tend to rely on gross over-simplification. (anaesthetist.com)
  • Part of the Oxford Textbooks in Anaesthesia series, this volume covers the anatomy and physiology, pharmacology, post-operative complications, critical care, and all clinical aspects of cardiac and thoracic anaesthesia. (b-ok.org)
