The upper respiratory tract can refer to the parts of the respiratory system lying above the vocal folds, or above the cricoid cartilage. [4] [5] The larynx is sometimes included in both the upper and lower airways. [6] The larynx is also called the voice box and has the associated cartilage that produces sound.
Long exposure to cigarette smoke induces airway inflammation and enlargement, which eventually restricts airflow and associates a high risk of V/Q mismatch. Also, obstructive sleep apnea is a sleep-related breathing disorder experiencing reduced breathing while asleep due to obstruction of the upper airway. It typically has a higher risk in ...
The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary ...
A bronchus (/ ˈ b r ɒ ŋ k ə s / BRONG-kəs; pl.: bronchi, / ˈ b r ɒ ŋ k aɪ / BRONG-ky) is a passage or airway in the lower respiratory tract that conducts air into the lungs.The first or primary bronchi to branch from the trachea at the carina are the right main bronchus and the left main bronchus.

In the unconscious patient, after the airway is opened the next area to assess is the patient's breathing, [11] primarily to find if the patient is making normal respiratory efforts. Normal breathing rates are between 12 and 20 breaths per minute, [14] and if a patient is breathing below the minimum rate, then in current ILCOR basic life ...
The lower respiratory tract is part of the respiratory system, and consists of the trachea and the structures below this including the lungs. [32] The trachea receives air from the pharynx and travels down to a place where it splits (the carina ) into a right and left primary bronchus .
