Germs and Viruses word list, defined
- 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.
- 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.
- TRACHEA /trəˈkiːə/ · noun
- The trachea, also known as the windpipe, is a tube that carries air from the throat to the lungs. It is a vital part of the respiratory system. Related: windpipe, airway, bronchus, larynx.
- 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.
- 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.
- 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.
- EPITHELIUM /ˌɛpɪˈθiːliəm/ · noun
- A thin layer of tissue that covers the surfaces of the body and lines its internal cavities and organs, such as the skin's outer layer, the lining of the gut, and the airways. Epithelial tissue consists of closely packed cells with little intervening matrix and serves protective, secretory, and absorptive functions. Related: epidermis, lining tissue, epithelial tissue, surface tissue.
- PLEURA /ˈplɪərə/ · noun
- The two thin layers of tissue that surround the lungs and line the chest cavity, or a fluid-filled space between these layers. In medicine, the pleura is a membrane that surrounds the lungs and lines the chest cavity. Related: pleurisy, pleuritis, pleural, pleuritic.
- 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.
- PHARYNX /ˈfærɪŋks/ · noun
- The pharynx is a muscular tube that connects the nose and mouth to the esophagus and larynx. It is also known as the throat. Related: throat, gullet, esophagus, larynx.
- 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.
- INHALATION /ɪnˈhælɪˌeɪʃən/ · noun
- The act of breathing in, or the process of taking air into the lungs. The act of inhaling a substance, such as a gas or a powder, into the body. Related: breathing in, inspiration, inhalation, respiration.
