olfactory epithelium - ANSWERSS✔️💫-contains the receptors for smell
Pharynx - ANSWERSS✔️💫-passageway for air to the larynx
glottis - ANSWERSS✔️💫-Opening between vocal cords
larynx - ANSWERSS✔️💫-upper most part of the trachea, contains the vocal cords
vocal cords - ANSWERSS✔️💫-folds of tissue that vibrate as air passes over them
Bronchi - ANSWERSS✔️💫-2 passages that lead air to the lungs
lungs - ANSWERSS✔️💫-elastic organs of gas exchange
bronchioles - ANSWERSS✔️💫-small tubes in the lungs that lead from the bronchi to the alveoli.
