How Do You Spell TERMINAL BRONCHIOLE?

1. A terminal bronchiole is a small, narrow tube-like structure that belongs to the respiratory system. It is a branching subdivision of the conducting bronchioles, which further divides and eventually leads to the creation of the respiratory bronchioles.

   The terminal bronchioles function as the ultimate pathway for the inhaled or inspired air within the lungs. They are responsible for the transportation of air from the larger bronchioles to the respiratory bronchioles. They mark the end of the conducting zone of the respiratory system and form the transition into the respiratory zone.

   Within the terminal bronchioles, the walls are lined with specialized cells called cuboidal epithelial cells. These cells have cilia on their surface, which aid in the movement of mucus and other particles trapped in the respiratory tract. The cilia help to push the mucus up towards the mouth, where it can be expelled from the body.

   Additionally, the walls of the terminal bronchioles contain no cartilage, unlike the larger bronchioles. This lack of cartilage allows for increased flexibility, which facilitates easier movement of air.

   The terminal bronchioles play a vital role in the respiratory system by delivering fresh air to the deeper regions of the lungs, where gas exchange with the bloodstream occurs.

2. Alveolar duct, the last division of an air-tube opening into a number of culs-de-sac, the infundibula or atria.

Common Misspellings for TERMINAL BRONCHIOLE

The word "terminal bronchiole" is composed of two components: "terminal" and "bronchiole".

1. "Terminal": The term "terminal" comes from the Latin word "terminus", meaning "boundary" or "end". In the context of the respiratory system, the "terminal" portion refers to the end or final part of the bronchiole tree before it branches into the respiratory bronchioles.

2. "Bronchiole": The term "bronchiole" comes from the Latin word "bronchiolus", meaning "small bronchus". The Latin word "bronchus" initially derived from the Greek word "bronkhos", referring to the windpipe or throat.

Therefore, combining these components, "terminal bronchiole" refers to the smallest branches or end parts of the bronchial tubes, which mark the boundary between conducting airways and respiratory airways in the lungs.
