The cilia of the primary bronchi mucosa functions by beating upward towards the larynx. As such, they conduct air into both lungs.
primary bronchi
True
The answer is true.
Cilia helps to "wave up" the mucus away from the deeper parts of the respiratory system. Debris/pathogens can stick to the mucus and then cilia can move up the mucus.
To filter out particles that are possibly harmful if allowed to reach your lungs.
Cilia
They are known as "cilia"
cilia prevents the entrance into the body by pathogen by constantly beat toward the outside of the body. If it is in your throat it will beat it toward your stomach so stomach acid can destroy the pathogen.
Away from the lung and toward the mouth and nasal cavity.
cilia
cilia
the goblet cells in the bronchioles produce a mucus which traps foreign substances in the airway such as pollen, pathogens and dust particles. The cilia of the ciliated cells will then waft the mucus and the trapped particles up to the larynx where it can be swallowed and the pathogens can be destroyed by the stomach acid. The cilia can waft due to the energy produced in the cells (in the form of ATP) by the mitochondria.
