Odor Receptors Found In Lungs
2014-01-03 10:22:27

Brett Smith for redOrbit.com - Your Universe Online New research published in the American Journal of Respiratory Cell and Molecular Biology has revealed that odor receptors aren’t just found in the nose – they also line the lungs as well. However, instead of being used to detect the aroma of blueberry cobbler or a succulent roasting chicken, the odor receptors in the lungs trigger a response designed to protect the airways. “We forget,” said study author Yehuda Ben-Shahar,...

A simple video camera paired with complex algorithms appears to provide an accurate means to remotely monitor heart and respiration rates day or night, researchers report. The inexpensive method for monitoring the vital signs without touching a patient could have major implications for telemedicine, including enabling rapid detection of a heart attack or stroke occurring at home and helping avoid sudden infant death syndrome, according to a study published in the journal PLOS ONE. It...

Common Stem Cell In Development Of Heart And Lungs Explains Adaption For Life On Land
2013-07-23 09:39:06

University of Pennsylvania School of Medicine The evolution of adaptations for life on land have long puzzled biologists -- are feathers descendents of dinosaur scales, how did arms and legs evolve from fins, and from what ancient fish organ did the lung evolve? Biologists have known that the co-development of the cardiovascular and pulmonary systems is a recent evolutionary adaption to life outside of water, coupling the function of the heart with the gas exchange function of the lung....

-Alveolar macrophage (AM) function plays a critical role in protecting the lungs by removing particulates. -Chronic drinking causes persistent oxidative stress in the lungs, leading to impaired AM function. -A new rodent study shows that chronic drinking appears to intensify lung damage caused by particulate matter. Alveolar macrophage (AM) function plays a critical role in protecting the lungs from particulate matter inhalation by removing particulates from the airway and secreting...

A paper recently published in the New England Journal of Medicine and co-written by physicians and scientists at the University of Colorado School of Medicine finds that an important genetic risk factor for pulmonary fibrosis can be used to identify individuals at risk for this deadly lung disease. Researchers looked at a fairly common variant of the gene for mucin-5B, a protein that is a component of the mucous produced by the bronchial tubes. While this variant of the MUC5B gene is...

Study offers understanding of asthma development The most common cause of lower respiratory tract infections in infants and young children, respiratory syncytial virus (RSV), can be transferred during pregnancy to an unborn baby, according to Cleveland Clinic Children's Hospital research published online this week in the journal PLOS ONE. In animal models, the study shows that RSV is able to spread across the placenta from the respiratory tract of the mother to the fetus, and is...

A research team from Birkbeck, University of London, Royal Holloway University and Uppsala University in Sweden, have helped explain how ozone causes severe respiratory problems and thousands of cases of premature death each year by attacking the fatty lining of our lungs. In a study published in Langmuir, the team used neutrons from the Institut Laue-Langevin in Grenoble and the UK's ISIS Neutron Source to observe how even a relatively low dose of ozone attacks lipid molecules that line...

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...

Pharynx

The pharynx is situated directly after the mouth and nose and lies right before the esophagus. Formation and Orientation The pharynx is divided into three separate sections. The nasopharynx is the first part of the pharynx that lies between the soft palate and the base of the skull. The pharyngeal tonsils are located on the back wall of the nasopharynx. This portion of the pharynx is connected to the middle easr by the Eustachian tubes. The nasopharynx is linked to the nasal cavities...

Trachea
2013-01-18 11:28:50

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
2013-01-01 15:53:59

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...
