Pregnant women who consumed seven servings per day of fruits and vegetables moderately reduced risk of upper respiratory infection, U.S. researchers say. Upper respiratory tract infections include the common cold and sinus infections, which can lead to lower respiratory problems, such as asthma or pneumonia. Senior author Martha M. Werler of the Slone Epidemiology Center at Boston University says eating nutritious foods, especially fruits and vegetables, improves immunity but that hadn't...

Italian researchers have discovered that human blood flow and respiratory rates can follow the pace of music, which suggests that doctors could one day use music as part of rehabilitation for patients suffering from heart disease or stroke. Writing in Circulation: Journal of the American Heart Association, Dr. Luciano Bernardi and colleagues said that the heart rate of healthy adults appeared to change along with the change in musical rhythms. The researchers had previously discovered that...

 More than one kind of stem cell is required to support the upkeep and repair of the lungs, according to a new study published in the journal Cell Stem Cell.Scientists at Duke University Medical Center painstakingly followed and counted genetically labeled cells in the mouse lung for over a year, under differing conditions, to learn more about natural renewal and healing processes. This information may shed light on what goes wrong in conditions like lung cancer, chronic bronchitis and...

Vitamin D may slow the progressive decline in the ability to breathe that can occur in people with asthma as a result of human airway smooth muscle (HASM) proliferation, according to researchers at the University of Pennsylvania. The group found that calcitriol, a form of vitamin D synthesized within the body, reduced growth-factor-induced HASM proliferation in cells isolated from both persons with asthma and from persons without the disease. The proliferation is a part of process called...

There may be a new way to predict mortality in patients with idiopathic pulmonary fibrosis (IPF), a devastating disease that slowly petrifies the lungs. Most patients live only three years after diagnosis on average; however, some remain stable for many years, while for others, the disease progresses more rapidly."There is no effective treatment [for IPF] and many patients, if eligible, are referred for lung transplantation. Identification of surrogate short-term measures of mortality is...

A new research study suggests Vicks VapoRub, the salve used to relieve cough and congestion symptoms, can cause severe breathing problems in children under 2 when inappropriately applied directly under the nose. Using the product in this way can cause a young child's tiny airways to swell and fill with mucus, triggering severe breathing problems, researchers wrote in the journal Chest. "The ingredients in Vicks can be irritants, causing the body to produce more mucus to protect the airway,"...

Hope is on the horizon for premature infants born before their lungs have a chance to fully develop. "Within minutes of birth, a baby relies solely on its lungs to get the oxygen it needs," study author Paul Kemp, from Cardiff University in the U.K., was quoted as saying. But lung development is one of the last things that occurs in the womb, so when babies are born too soon, their lungs don't have the ability to take in enough oxygen to supply the bloodstream. This results in respiratory...

Cystic Fibrosis
2013-07-19 15:03:45

Cystic fibrosis, also called mucoviscidosis, is an autosomal recessive genetic disorder of the viscous secretions in the body. In turn, it effects the lungs, pancreas, liver, and intestines, as well as all other exocrine glands in the body. The most common genetic mutation that causes CF is a deletion of three nucleotides that results in a loss of phenylalanine, an amino acid at the 508th position on the protein. It should be noted, however, that there are over a thousand other mutations that...

This portion of the pharynx is connected to the middle easr by the Eustachian tubes. The nasopharynx is linked to the nasal cavities...

Trachea

The trachea, commonly called the windpipe, is the air passage-way from the mouth to the lungs. Non-fish vertebrae all have a trachea. The moist with mucus walls of the tube-like structure trap inhaled particles to keep them from entering the lungs. Structure The trachea is an open-ended cylindrical structure that starts at the larynx and ends at the bifurcation. It is about one inch in diameter and can run four to six inches in length. Within the pipe there are anywhere from 15 to 20...

Lung

The lung is a vital organ that is a part of the respiratory system. Generally a person has two lungs; however, the body can function with only one. The lung’s main function is to move oxygen and carbon dioxide into and out of the bloodstream through gas exchange. The lungs are located lateral to the heart in the thoracic cavity. Each lung has a tip called the apex, which is superior in the body. The bases of the lungs rest on the diaphragm. They appear to be spongy due to their bundles of...
