What is the route of air from the external nares to alveolus?

Nostrils → Nasal Cavity → Pharynx → Larynx → Trachea → Main Bronchus → Lobar Bronchiole → Segmental Bronchus → Bronchiole → Terminal Bronchiole → Respiratory Bronchiole → Alveolar Duct → Atrium → Alveolus


What is a small Airsac on the tip of a bronchiole?

A small air sac at the tip of a bronchiole is called an alveolus. Alveoli are tiny, balloon-like structures in the lungs where the exchange of oxygen and carbon dioxide occurs. They are essential for efficient gas exchange, allowing oxygen to enter the bloodstream and carbon dioxide to be expelled. Each alveolus is surrounded by a network of capillaries that facilitate this process.

What are at the end of each bronchiole are tiny air sacs called?

The small sacs at the end of the Bronchial tubes are called the anus.PL77 * erm i think you have the wrong organ system, that is the end of the digestive system bronchial tubes are in the respiratory system and the small sacs attached to the bronchial tubes are called alveoli they are air sacs in the lungs*


What are the 3 types of bronchioles?

The three types of bronchioles are terminal bronchioles, respiratory bronchioles, and conducting bronchioles. Terminal bronchioles are the smallest airways in the respiratory system that lead to the respiratory bronchioles where gas exchange occurs. Conducting bronchioles are larger airways that branch off the main bronchi and help to conduct air to the smaller bronchioles.
