Abstract: Air pollution has become an extremely serious problem, with particulate matter having a significantly greater impact on human health than other contaminants. The small diameter of fine ...

Emphysema. Three-dimensional computed tomography (CT) scan of the lungs, showing advanced emphysema of the right lung (left). Emphysema is a disease in which the tiny air sacs (alveoli) of the lung ...

The bronchi are tubes that carry air from the trachea to the lungs and back out. The bronchi help trap and remove germs that can make you sick. Bronchitis, asthma, and COPD are some conditions that ...

What Is the Respiratory System? When we breathe, the respiratory system takes in oxygen and sends out carbon dioxide. The cells in our bodies need fresh oxygen to stay alive. As cells do their jobs, ...

Bronchiolitis obliterans is a chronic lung disease that also goes by the nickname “popcorn lung.” The condition damages the tiniest airways in your lungs (bronchioles), causing coughing and shortness ...

Bronchioles are tiny air passages in the lungs that deliver air to the alveoli. Conditions like asthma and emphysema can block or narrow the bronchioles, making it hard to breathe. Bronchodilators and ...

Abstract: Respiratory diseases, particularly chronic obstructive pulmonary disease (COPD), are a major global health concern, yet existing clinical tools fall short in accurately assessing airflow ...

Constrictive bronchiolitis obliterans is an important respiratory illness because of its underlying irreversible fibrotic process, and is defined as concentric fibrosis in the bronchiolar submucosal ...

A narrowing of the smallest airways in the lung (bronchioles) causes wheezing. This narrowing results from swelling caused by a virus. The respiratory syncytial virus (RSV) causes most bronchiolitis.

The autonomic nervous system (ANS) is a critical component of the human body, regulating involuntary physiological functions such as heart rate, digestion, respiratory rate and pupillary response. It ...

A narrowing of the smallest airways in the lung (bronchioles) causes wheezing. This narrowing results from swelling caused by a virus. The respiratory syncytial virus (RSV) causes most bronchiolitis.

Bronchiolitis is a common lung infection among infants. It can cause coughing, wheezing, and a hard time with breathing. While most cases can be treated at home, it’s also the leading reason infants ...
