The Respiratory System word list, defined

ALVEOLI /ælˈviːəlaɪ/ · noun
The plural of alveolus; in anatomy, the tiny air sacs at the ends of the bronchioles in the lungs where gas exchange between air and blood takes place. The term is also used in dentistry for the bony sockets in the jaw that anchor the teeth. Related: air sacs, pulmonary alveoli.
BRONCHI /ˈbrɒŋkaɪ/ · noun
The two main branches of the windpipe (trachea) that lead into the left and right lungs, where they divide into progressively smaller airways. Related: airways, windpipe branches, breathing tubes.
CAPILLARY /ˈkæpəˌlɛri/ · noun, adjective
As a noun, a capillary is any of the tiny, thin-walled blood vessels that form a network between the arterioles and venules, through which oxygen, nutrients, and waste are exchanged with body tissues. As an adjective, it describes something relating to or resembling such fine vessels, or having the properties of capillarity — the movement of liquid through very narrow spaces. Related: capillary vessel, hairline vessel, microvessel, blood vessel.
CILIA /ˈsɪliə/ · noun
Cilia are the tiny, hairlike projections that line the surfaces of certain cells in the body — most famously in the respiratory tract, where they sweep mucus and debris away from the lungs — as well as the short hairs of the eyelids; in many organisms they also serve to propel movement. Related: eyelashes, hairs.
DIAPHRAGM /ˈdaɪ.ə.fræm/ · noun
A dome-shaped sheet of muscle separating the chest cavity from the abdominal cavity, whose contraction draws air into the lungs during breathing; also, a thin dividing membrane or partition, or a device such as a contraceptive cap or the vibrating plate in a microphone. Related: partition, membrane, divider, septum.
EPIGLOTTIS /ˌɛpɪˈɡlɒtɪs/ · noun
A thin, leaf-shaped flap of cartilage located behind the tongue at the entrance to the larynx, which folds down over the windpipe during swallowing to prevent food and liquid from entering the airway.
EXPIRATION /ˌɛkspɪˈreɪˈʃən/ · noun
The act or process of coming to an end, especially of a fixed period of time such as that covered by a contract, license, or warranty; also the act of breathing out air from the lungs. Related: termination, expiry, cessation, conclusion.
INSPIRATION /ɪnˈspɪrəʃən/ · noun
A feeling or idea that inspires someone to do something, or a person or thing that inspires someone. A creative impulse or idea. Related: motivation, stimulus, encouragement, incentive.
LARYNX /ˈlærɪŋks/ · noun
The part of the throat containing the vocal cords, which produce sound when vibrating. In humans, it is located below the pharynx and above the trachea. Related: voice box, Adam's apple, glottis, vocal cords.
LUNGS /lʌŋz/ · noun
The organs in the chest that take in oxygen and expel carbon dioxide during breathing. The lungs are essential for the exchange of gases between the body and the air. Related: breasts, lungs, pleura, thorax.
MUCUS /mjuːkəs/ · noun
A thick, protective fluid produced by the mucous membranes in the body, often associated with illness or infection. It can also refer to a thick, sticky substance produced by plants or other organisms. Related: phlegm, sputum, discharge, secretion.
NASAL /nɑːzəl/ · adjective
