airway length - a large surface area means more friction airway radius - halving the radius increases resistance 16-fold flow rate
Airway resistance is primarily regulated by the diameter of the airways, which can change due to various factors. Smooth muscle contraction or relaxation in the bronchial walls, influenced by autonomic nervous system activity and inflammatory mediators, plays a key role in this regulation. Additionally, factors such as airway inflammation, mucus production, and external stimuli like allergens or smoke can also impact airway resistance. Overall, these mechanisms work together to maintain optimal airflow during breathing.
Three common types of airway obstructions include foreign body aspiration, which occurs when an object lodges in the airway; swelling from anaphylaxis or severe allergic reactions, which can restrict airflow; and mucus plugs, often seen in conditions like asthma or chronic bronchitis, that block the airways. Each of these obstructions can lead to difficulty breathing and requires prompt medical attention.

An airway that is not blocked. If you can breathe easily, you have an active airway. If you are choking, you do not.

1) provides a patent (open) airway. 2) acts as a switching mechanism to route air/food to the proper channels. 3) voice production
The nose, pharynx, and trachea are the parts of the upper airway. The tubes of the lungs comprise the lower airway.

Airway beacon was created in 1923.
Daimler Airway was created in 1919.
If a person becomes unconscious, an airway may be used to insure that the airway stays open.
The epiglottis is a flap that acts like a "door" and seals off your airway while you are swallowing food, and then opens to allow you to breathe when you are not swallowing food. When you are eating, make sure that you do not talk, as this interferes with the function of the epiglottis and can cause food to enter your airway.
