Airway Anatomy

Anatomy of the Respiratory System The organs of the respiratory system include the nose pharynx larynx trachea bronchi and their smaller branches and the lungs which contain the alveoli. The upper airway consists of the pharynx and the nasal cavities.

Upper Airway Anatomy Functions warm filter and humidify air Nasal cavity and nasopharynx Formed by union of facial bones Nasal floor towards ear not eye Lined with mucous membranes cilia Tissues are delicate vascular Adenoids Lymph tissue - filters bacteria Commonly infected.

Airway anatomy. The nose is the primary airway used by most conscious adults to breathe. This section also describes the functional physiology of this airway. The airway is a continuous passageway but can be further categorized into the upper and lower airway.

The upper airway includes the nasal and oral cavities the pharynx and the larynx. Airflow requires a patent upper airwayAirflow requires a patent upper airway. There are 3 major parts of the respiratory system.

Nose Paranasal sinuses 2. It is a common pathway for respiratoryIt is a common pathway for respiratory digestive and phonatory functionsdigestive and phonatory functions. Endotracheal intubation can be done either nasally or orally but oral intubation is easier in most contexts.

First responders need to be familiar with respiratory system anatomy in order to keep patients healthy breathing and adequately ventilated. IT_AM 11 Describe the basic structural anatomy of the upper airway including the larynx. Supraglottic larynx consists of epiglottis falseventricular folds aryepiglottic folds and the arytenoids.

It includes the mouth the nose the palate the uvula the pharynx and the larynx. State of consciousness is a majorState of consciousness is a major determinant of pharyngeal. Functions of the airway include phona-tion olfaction digestion humidiﬁcation and warm-ing of inspired air 3.

This is a preview of subscription content log in to check access. The space behind the nostrils the nasopharynx is filled with blood-rich tissue covered in mucus which warms and cleans incoming air. They form a border between the laryngeal airway anteriorly and the piriform sinuses posteriorly Fig.

Below are detailed graphics of both the upper and lower respiratory tracts. The Upper Airway is a MultipurposeThe Upper Airway is a Multipurpose PassagePassage. The upper airway begins in the nose though many nasal structures extend into.

However some authors include the larynx and trachea as well. The upper airway begins from the nares and oropharynx to the vocal cords Fig. Airway anatomy can be divided into the upper airway and the lower airway.

The nose is composed of bone and cartilage which are in turn attached to the facial skeleton. The airways also serve other important functions such as olfaction deglutition and phonation. Application of UE videolaryngoscopy in patients with an abnormal airway anatomy and undergoing cerebral aneurysm embolization in Chinese.

Assessment Introduction The airway extends from the external nares to the junction of the larynx with the trachea. Ok are you on board so far. Aryepiglottic folds appear at the anterolateral aspect of the larynx and are triangular in shape.

The lower airway is located below the level of the vocal cords and extends distally. As it goes further down the trachea splits into two mainstem bronchi one leading to the left lung and the other leading to the right lung. The pharynx is can be divided into the nasopharynx oropharynx and laryngopharynx.

The airway which includes the nose mouth pharynx larynx trachea bronchi and bronchioles carries air between the lungs and the bodys exterior. Respiratory System Anatomy and Physiology Part 3. The lungsContinue Scrolling To Read More Below.

The functional design is far from ideal because ingested food and water must traverse the upper airway to reach the alimentary tract. To get the most benefit out of this post print out the diagram below. BT_AM 11 Describe the anatomy of the upper airway larynx and trachea.

It transmits air liquids and solidsIt transmits air liquids and solids. The anatomy of the upper airway can be broken down into the nose mouth and throat. AIRWAY ANATOMY UPPER AIRWAY Part above cricoid cartilage 1.

It includes the nose the paranasal sinuses the pharynx and the larynx 2. The medical terms for these are the nasopharynx and oropharynxlarynx. The valleculae are separated from one another by the glossoepiglottic ligament.

The pharynx must serve two conflicting functions. The airway the lungs and the muscles of respiration. A quick overview is as follows.

Current Evidences for the Use of UEscope in Airway Management This shape mimics upper airway anatomy resulting in low resistance and allowing anatomical insertion. The upper airway extends from the mouth to the trachea. The anatomy of the airway begins with the nose and nasal cavity or oral cavity then proceeds through the pharynx past the epiglottis into the larynx where your vocal cords are down the trachea through the bronchial tree and into the lungs.

Upper Airway Anatomy and Function. For the purpose of description the airway is divided into the upper airway which extends from the nose to the glottis or thoracic inlet and the lower airway which includes the trachea the bronchi and the subdivisions of the bronchi. Thats because its easier to visualize most of the airway.

So the next part of the respiratory system anatomy and physiology is the trachea the windpipe. Knowledge of the functional anatomy of the airway in these forms the basis of understanding the pathological conditions that may occur. Understanding airway anatomy is vital to proper intubation.
