The major passages and structures of the upper respiratory tract include the nose or nostrils, nasal cavity, mouth, throat (pharynx), and voice box (larynx). The respiratory system is lined with a mucous membrane that secretes mucus.
What is the upper airway?
Upper Airway It is the region between the palate and the hyoid bone, anteriorly divided from the oral cavity by the tonsillar arch. The hypopharynx connects the oropharynx to the esophagus and the larynx, the region of pharynx below the hyoid bone.
What structures compose the upper and lower airway?
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 folds (cords). The lower airways or lower respiratory tract includes the portion of the larynx below the vocal folds, trachea, bronchi and bronchioles.
What are the structures in the upper respiratory system quizlet?
The upper respiratory tract includes the nose, mouth, nasal cavity, pharynx, and larynx. The lower respiratory tract consists of the trachea, bronchi, bronchioles, and lungs.Which of the following structures is not a part of the upper airway?

What structures make up the upper and lower respiratory tracts quizlet?
Structurally, the respiratory system consists of two parts: (1) The upper respiratory system includes the nose, nasal cavity, pharynx, and associated structures. (2) The lower respiratory system includes the larynx, trachea, bronchi, and lungs.
What creates an upper respiratory airway?
The Nose and Nasal Cavities Provide Airways for Respiration. The nasal cavities are chambers of the internal nose. In front, the nostrils, or nares, create openings to the outside world. Air is inhaled through the nostrils and warmed as it moves further into the nasal cavities.
Which of the following are structures found within the respiratory system?
- Nose.
- Mouth.
- Throat (pharynx)
- Voice box (larynx)
- Windpipe (trachea)
- Large airways (bronchi)
- Small airways (bronchioles)
- Lungs.
Which structure in the upper respiratory system covers the larynx during swallowing?
The epiglottis is usually upright at rest allowing air to pass into the larynx and lungs. When a person swallows the epiglottis folds backward to cover the entrance of the larynx so food and liquid do not enter the windpipe and lungs.
Which of the following is a function of the upper airway quizlet?1. The upper airway not only provides a passage for air to be breathed in and out of the lungs, but it also heats, humidifies and filters the air and is involved in cough, swallowing and speech. 2.
Article first time published onIs the trachea part of the upper airway?
The upper respiratory tract consists of the nose, the nasal cavity and the pharynx. The lower tract consists of the larynx, the trachea , the bronchi and the lungs.
Is the epiglottis part of the upper airway?
It is situated directly above the trachea and makes up the lowest part of the upper respiratory tract. … While swallowing, the epiglottis closes off the airway and ensures food/liquid moves into the esophagus. GLOTTIS: The glottis is a slit in the base of the trachea, ringed by the vocal cords.
What are the 3 parts of the upper respiratory tract?
The upper airways are made of the nose, nasal cavity, and pharynx while the lower airways are the larynx; trachea, bronchial tree and the lungs.
Which of the following structure is not the part of respiratory tree?
The structure which is not a part of the respiratory system is (c) Heart. Explanation: The alveoli is the site where the exchange oxygen and carbon dioxide takes place between blood and alveoli during the process of breathing in and breathing out.
Where is the upper respiratory system located?
Upper respiratory tract: Composed of the nose, the pharynx, and the larynx, the organs of the upper respiratory tract are located outside the chest cavity.
Which of the following structures connects the nose to the throat?
Pharynx — is the muscle-lined space that connects the nose and mouth to the larynx and esophagus (eating tube).
Which structure of the upper respiratory tract serves as the passageway for both food and air?
The two openings of the airway (the nasal cavity and the mouth) meet at the pharynx (FAR-inks), or throat, at the back of the nose and mouth. The pharynx is part of the digestive system as well as the respiratory system because it carries both food and air.
What is the basic anatomy and physiology relating to upper airway?
The upper airway extends from the mouth to the trachea. It includes the mouth, the nose, the palate, the uvula, the pharynx, and the larynx. This section also describes the functional physiology of this airway.
What functions do the structures of the upper respiratory tract perform?
Upper respiratory tract organs provide a route for air to move between the outside atmosphere and the lungs. They also clean, humidity, and warm the incoming air. However, no gas exchange occurs in these organs.
What structures are part of the 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. Deep in the lungs, each bronchus divides into secondary and tertiary bronchi, which continue to branch to smaller airways called the bronchioles.
Which of the following structures is part of the respiratory system quizlet?
What structures make up the respiratory system? Nose, pharynx, larynx, trachea, bronchi, and lungs.
Which structure of the respiratory system connects the pharynx to the trachea bronchi larynx nasal cavity lungs?
Larynx. The larynx is a cartilaginous structure inferior to the laryngopharynx that connects the pharynx to the trachea and helps regulate the volume of air that enters and leaves the lungs. The structure of the larynx is formed by several pieces of cartilage.
Why is the upper part of the voice box covered by a flap?
The larynx contains the vocal cords. … The opening to the larynx is covered by a large muscular flap called the epiglottis. The epiglottis covers the windpipe when we swallow, to prevent food from entering the trachea. The muscles of the larynx also help close the opening to the airway.
Which structure prevents swallowed food from going into the trachea?
First, the tongue pushes the food into the throat. Next, the epiglottis, a small but important flap of tissue, folds over the voice box at the top of the windpipe. This keeps food from going down the wrong way.
Which components are part of the upper respiratory system check all that apply?
- epiglottis.
- larynx.
- nose.
- pharynx.
- sinuses.
Which are found in the mucous lining the respiratory tract?
The mucous membrane lining the RESPIRATORY TRACT, including the NASAL CAVITY; the LARYNX; the TRACHEA; and the BRONCHI tree. The respiratory mucosa consists of various types of epithelial cells ranging from ciliated columnar to simple squamous, mucous GOBLET CELLS, and glands containing both mucous and serous cells.
What structures are used by both the respiratory and digestive systems?
There are three main divisions of the pharynx: the oral pharynx, the nasal pharynx, and the laryngeal pharynx. The latter two are airways, whereas the oral pharynx is shared by both the respiratory and digestive tracts.
