Bronchioles and bronchioli are synonyms for the term bronchis. All these terms refer to the small, air-conducting tubes that branch off from the bronchi and further divide into tiny air sacs called alveoli. The bronchioles are in charge of delivering oxygen to the alveoli where the gas exchange process takes place. The bronchi and bronchioles are vital to the respiratory system to ensure proper breathing processes, and any blockage or infection can cause severe respiratory issues such as chronic obstructive pulmonary disease (COPD) or bronchitis. Understanding the synonyms of bronchis can help individuals learn more about the respiratory system and its functions.
