The conducting airways transport atmospheric gases down the respiratory tract to the respiring airways, where gas exchange takes place. Gas exchange does not take place in the conducting airway, which contains cartilage, cilia, and mucosal cells.
Primary bronchus
Fungi can cause respiratory tract infection when inhaled. The spores finds its way in a warm-moist environment, starts to grows, and later blocks small airways.
it makes the cilia clump together so they cannot prevent harmful materials from getting into the lungs.The tar sticks to the cilia, paralysing them, and making them unable to clear the airways of dust and bacteria.
The volume of the conducting airways of the nose, mouth, and http://www.answers.com/topic/trachea down to the level of the http://www.answers.com/topic/alveolus, representing that portion of inspired gas http://www.answers.com/topic/unavailability for exchange of gases with http://www.answers.com/topic/pulmonary capillary blood Each minute, under resting conditions, we breathe in about six liters of fresh air. About 1/3 of this air stays in the mouth, throat, and large airways where no gas exchange takes place; this region (the upper airways and part of our lungs) is referred to as "dead space," because air in this space doesn't take part in gas exchange. The remaining four liters of fresh air breathed in each minute are distributed to the hundreds of millions of alveoli and it this air that takes part in gas exchange and constitutes the alveolar ventilation.
RSV stands for respiratory syncytial virus, the most frequent cause of serious respiratory tract infections in infants and children younger than 4 years of age. RSV causes nasal stuffiness and discharge, cough, and sometimes ear infections.

An anatomic dead space is a volume of conducting airways of the lung, as measured by a cast of the airways.
Respiratory airways
Primary bronchus
Airways are for planes, waterways are for boats.
dead space (VDS) air 150 ml stays in the conducting airways during Minute ventilation.For each tidal volume (VT) of 500 ml air inspired, 150 ml stays in the conducting airways, it does not participate in gas exchange. It merely enters and subsequently leaves the conducting airways. The remaining 350 ml of the tidal breath enters the alveoli (VA) and participates in gas exchange.
The respiratory system, of mammals in particular, consists of respiratory airways, lungs and muscles concerned with respiration. The respiratory airways include the trachea, bronchiole, alveoli. Lungs perform function of exchange of gases. Muscles of the diaphragm contribute to breathing activity.

Goblet cells are in the respiratory epithelium, which lines the airways from the pharynx down into the lungs. They secrete mucous.

Airways are companies that fly people from an airport to another.
