Anatomy and Physiology: The Upper Respiratory System The structures of your upper respiratory system are always working overtime—filtering air, expelling pollutants, and relying on other anatomy to remain healthy and intact. Let's take a look at some of the structures and jobs of the upper respiratory system. Nasal Cavity The nasal cavity is a chamber of the internal nose that connects to the nasopharynx. Air is inhaled through the nostrils and warmed as it passes through the nasal cavities.

What are Bronchial Tubes? The bronchial tubes are part of an internal structure known as the respiratory tree. This structure is part of the respiratory system, which allows humans to exchange the air in their lungs. People need to breathe in air that is rich in oxygen. The air they breathe out has poor levels of oxygen.

- A bronchopleural fistula is a communication between the bronchial tree and pleural space. Clinically, it may be best described as a persistent air leak or a failure to re-inflate the lung despite chest tube drainage for 24 h.

Lung Anatomy The anatomy of the respiratory system can be divided into 2 major parts, airway anatomy and lung anatomy. Airway anatomy can be further subdivided into the following 2 segments: The extrathoracic (superior) airway, which includes the supraglottic, glottic, and infraglottic regions.

Airway Anatomy and Physiology (Clinical Essentials) (Paramedic Care) Part 1 The larynx, also known as the voice box, is the upper group of structures of the lower airway and opens with a number of cartilaginous structures. From anterior to posterior, these structures include the base of the epiglottis, the thyroid cartilage, and the aryepiglottic folds (Figure 20-5b and Figure 20-5c).

- Stridor is produced by the rapid, turbulent flow of air through a narrowed or partially obstructed segment of the extrathoracic upper airway. Involved areas include the pharynx, epiglottis, larynx, and the extrathoracic trachea.

Respiratory tract The upper respiratory tract, can refer to the parts of the respiratory system lying above the sternal angle (outside of the thorax), above the glottis (vocal cords), or above the cricoid cartilage.So that the larynx is sometimes included in the upper airway and sometimes in the lower airway.he lower airways or lower respiratory tract includes the portion of the larynx below the vocal cords, trachea, bronchi and bronchioles. The lungs can be included in the lower respiratory tract or as separate entity and include the respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli.

EOA Abbreviation: OPA. A curved plastic device used to establish an airway in a patient by displacing the tongue from the posterior wall of the oropharynx. The device should be equal in length to the distance either from the corner of the mouth to the earlobe or from the center of the mouth to the angle of the jaw.

Larynx Larynx, also called voice box, a hollow, tubular structure connected to the top of the windpipe (trachea); air passes through the larynx on its way to the lungs. The larynx also produces vocal sounds and prevents the passage of food and other foreign particles into the lower respiratory tracts. The larynx is composed of an external skeleton of cartilage plates that prevents collapse of the structure. The plates are fastened together by membranes and muscle fibres.

Respiratory Tract The respiratory tract can be categorized into upper and lower compartments. The upper airway extends from the sinonasal region to the larynx. The cells of the upper airway are occasionally seen in lower respiratory tract specimens. The lower respiratory tract, which is the major focus of diagnostic respiratory cytopathology, extends from the trachea to the lungs.

Upper Airway Anatomy Upper Airway Anatomy. The upper airway consists of the pharynx and the nasal cavities; however, some authors include the larynx and trachea as well. The pharynx is can be divided into the nasopharynx, oropharynx, and laryngopharynx. The nose is composed of bone and cartilage, which are in turn attached to the facial skeleton. It is a pyramidal structure that is divided by a midline septum into two nasal cavities.

- The respiratory tract is divided into the upper airways and lower airways. The upper airways or upper respiratory tract includes the nose and nasal passages, paranasal sinuses, the pharynx, and the portion of the larynx above the vocal cords.he upper respiratory tract, can refer to the parts of the respiratory system lying above the sternal angle (outside of the thorax), above the glottis (vocal cords), or above the cricoid cartilage. So that the larynx is sometimes included in the upper airway and sometimes in the lower airway.

- sound transmission, two microphones are placed above and below the glottis while low-frequency sound is introduced via loudspeaker at the mouth. Obviously, those methods can only be used with cooperative subjects. Nonacoustic imaging and measurement of upper airway obstruction can be achieved with roentgenography and endoscopy, with cine computer tomography,50 and with

The Lungs and Respiration The following are structures that assist in the transportation of air to the lungs. 1  Nose and Mouth - openings that allow outside air to flow into the lungs. 2  Pharynx (throat) - directs air from the nose and mouth to the larynx. 3  Larynx (voice box) - directs air to the windpipe and contains vocal cords for vocalization.

Respiratory tract Anatomy and Function of the Respiratory System. The human respiratory system is divided into the upper and lower respiratory tracts. Upper respiratory tract. The major passages and structures of the upper respiratory tract include the nose or nostrils, nasal cavity, mouth, throat (pharynx), and voice box (larynx).

- Lower respiratory tract. The major passages and structures of the lower respiratory tract include the windpipe (trachea) and within the lungs, the bronchi, bronchioles, and alveoli. After the inhaled air moves through the larynx, it reaches the trachea. The trachea is a rigid tube about 4.5 inches long and 1 inch wide. Embedded in the walls of the trachea, C-shaped cartilage rings give the trachea rigidity and allow it to stay open all the time.

The Tracheobronchial Tree The trachea, bronchi and bronchioles form the tracheobronchial tree – a system of airways that allow passage of air into the lungs, where gas exchange occurs.ey: Green – upper lobe, yellow – middle lobe, blue – lower lobe. It travels inferiorly into the superior mediastinum, bifurcating at the level of the sternal angle (forming the right and left main bronchi). As it descends, the trachea is located anteriorly to the oesophagus, and inclines slightly to the right.

Upper Respiratory Tract Infection In addition to these intense physical barriers in the upper respiratory tract, the immune system also does its part to fight the invasion of the pathogens or microbes entering the upper airway. Adenoids and tonsils located in the upper respiratory tract are a part of the immune system that help fight infections.

airway nasopharyngeal airway. A soft, flexible, uncuffed tube placed through the nasal passages so that the distal tip rests in the nasopharynx. It is used to maintain the free passage of air to and from the lungs in patients with facial trauma or lockjaw or in nearly comatose patients who are breathing spontaneously. Before the tube is inserted, the proper length is determined by comparing it to the distance from the tip of the patient's nose to the earlobe.

- From the pharynx, air enters into the larynx, commonly called the voice box. The larynx is part of the upper respiratory tract that has two main functions: a passageway for air to enter into the lungs, and a source of vocalization.

Respiratory System Larynx. A rigid structure at the top of the trachea (so it is part of trachea, I assume) made completely out of cartilage. The larynx has three main functions: (1) its rigidness ensures that the trachea is held open (provides an open airway).
