Asthma is a respiratory illness that affects the lungs, trachea and bronchial passages. An asthma attack occurs when the respiratory system, collectively known as the airways, constricts and prevents oxygen from flowing freely into the body, according to Dr. Miles Weinberger, professor of pediatrics at University of Iowa Children's Hospital.Know More
The trachea is a long air tube leading from the neck to the upper chest cavity where it bisects to form the left and right bronchi. Each bronchus forks into several tiny passageways, or bronchioles, that deliver air to small sacs in the lungs known as alveoli. A smooth muscular lining runs throughout the airways and contains a membrane that produces mucus, which normally helps the respiratory system prevent the spread of bacteria in the lungs, says Dr. Weinberger.
During an asthma attack, the muscular lining swells or tightens, causing labored breathing, and the mucus membrane produces excess fluid, filling up the narrow airways, notes the American Lung Association. An asthmatic's respiratory organs are sensitive to specific stimuli, such as dust, pet dander, smoke or cold weather. Untreated or incorrectly managed asthma can lead to long-term respiratory damage from repeated inflammation. When the respiratory system is permanently scarred, medications lose their effectiveness and the lungs may not be able to distribute air sufficiently.Learn more about Conditions & Diseases
Terminal bronchioles are the air passages into the lungs. They branch into respiratory bronchioles and secrete a nonsticky surfactant to maintain the airway. Surfactant is a proteinaceous compound that maintains the airway in the smallest bronchioles and alveoli by keeping surface tension during inspiration and keeping them from collapsing during expiration.Full Answer >
The vomer bone is a thin, flat bone that forms part of the separation between the nasal passages. This bone divides the nostrils and appears in the skull of most vertebrates.Full Answer >
Black mold produces toxins called mycotoxins that can irritate the skin and air passages following exposure, notes MedicineNet. Severe reactions, such as difficulty breathing, may also develop, although this is uncommon. Allergic reactions, such as sneezing, tearing, coughing and wheezing, are the most common bodily effects related to mold exposure.Full Answer >
Nasal surgery can help sleep apnea by opening up the passages in your nasal cavity allowing for air to pass through without obstruction. Even though these surgeries help in most cases, it's not a guarantee.Full Answer >
