The Respiratory System word list, defined
- ALVEOLI /ælˈviːəlaɪ/ · noun

Related: partition, membrane, divider, septum.
- TRACHEA /ˈtreɪkiə/ · noun
- The trachea, or windpipe, is a flexible tube supported by cartilage that carries air from the larynx to the two main bronchi of the lungs. In insects, tracheae are branching respiratory tubes that carry air directly to the body's tissues. Related: windpipe.
- LARYNX /ˈlærɪŋks/ · noun
- The larynx is the anatomical structure in the neck that forms the upper part of the airway and contains the vocal folds, which produce the voice. In humans, it is commonly called the voice box. Related: voice box, upper windpipe.

- LUNGS /lʌŋz/ · noun
- The pair of organs in the chest that perform respiration, taking in oxygen and removing carbon dioxide from the body. Related: respiratory organs, air sacs.
- OXYGEN /ˈɒksɪdən/ (British), /ˈɑːksɪdən/ (American) · noun

- RESPIRATION /rˌɛspəˈreɪʃən/ · noun
