Damaged lungs regenerated in study

A new technique to rehabilitate lungs that are too damaged to be considered for transplant could benefit an increasing population of patients with end-stage lung disease.

Genetics

Researchers discover new disease

A new immunodeficiency disease caused by a novel genetic mutation has been identified by researchers at the University of Colorado Anschutz Medical Campus providing unique insights into cell biology.

The lungs never forget: Specialised T-cells remember allergens

According to a current study of the Medical University Vienna, specialised T memory lymphocytes in the lungs that react to inhaled allergens, cause attacks of allergic asthma. These T-helper 2-tissue resident memory cells, ...

Immune system boost could prevent lung cancer

Genomic differences related to the immune system may play a key role in the early development of lung cancer. That finding, published April 23, 2019, in Nature Communications, reveals potential for developing new therapeutics ...

New rules for lung transplants lead to unintended consequences

A donated lung suitable for transplant is a scarce resource. For this reason, the national policy determining which patients on the lung transplant waiting list will receive such an organ has provoked significant discussion ...

Lung cancer under-recognized in people who have never smoked

A group of respiratory medicine and public health experts are calling for lung cancer in never-smokers to be given greater recognition. Writing in the Journal of the Royal Society of Medicine, they say that lung cancer in ...

Lung

The lung or pulmonary system is the essential respiration organ in air-breathing animals, including most tetrapods, a few fish and a few snails. In mammals and the more complex life forms, the two lungs are located in the chest on either side of the heart. Their principal function is to transport oxygen from the atmosphere into the bloodstream, and to release carbon dioxide from the bloodstream into the atmosphere. This exchange of gases is accomplished in the mosaic of specialized cells that form millions of tiny, exceptionally thin-walled air sacs called alveoli.

In order to completely explain the anatomy of the lungs, it is necessary to discuss the passage of air through the mouth to the alveoli. Once air progresses through the mouth or nose, it travels through the oropharynx, nasopharynx, the larynx, the trachea, and a progressively subdividing system of bronchi and bronchioles until it finally reaches the alveoli where the gas exchange of carbon dioxide and oxygen takes place.

The drawing and expulsion of air (ventilation) is driven by muscular action; in early tetrapods, air was driven into the lungs by the pharyngeal muscles, whereas in reptiles, birds and mammals a more complicated musculoskeletal system is used.

Medical terms related to the lung often begin with pulmo-, from the Latin pulmonarius ("of the lungs"), or with pneumo- (from Greek πνεύμων "lung")
