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.


About how thick is hypha?

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*


How many subunits in thick filament?

Thick filaments in muscle fibers are primarily composed of myosin molecules, which consist of two heavy chains and four light chains each. Each thick filament is typically made up of around 200 to 300 myosin molecules, giving it a complex structure. This arrangement allows for the interaction with thin filaments during muscle contraction.
