These are called cilia.
In 2011, it was estimated that respiratory tract infections were responsible for approximately 3 million deaths worldwide. These infections include pneumonia, influenza, and other respiratory illnesses. The burden of respiratory infections disproportionately affects young children, the elderly, and individuals with pre-existing health conditions. Efforts to improve vaccination and access to healthcare have been ongoing to reduce these fatalities.
One statement that is not true of cilia in the respiratory tract is that they are responsible for gas exchange. Cilia are actually tiny hair-like structures that help move mucus and trapped particles out of the airways, but they do not participate in the exchange of oxygen and carbon dioxide. Their primary function is to keep the respiratory tract clear of debris and pathogens.
If the respiratory tract is not moist, it can lead to irritation and inflammation of the airways, making it more difficult to breathe. Dry air can impair the mucociliary clearance mechanism, reducing the effectiveness of the body's natural defense against pathogens and irritants. This may increase the risk of infections, exacerbate asthma or allergies, and cause discomfort such as coughing or a sore throat. Overall, maintaining moisture in the respiratory tract is essential for optimal respiratory health.

The trachea is the airway in the respiratory system.
At six months old, an infant's respiratory rate typically ranges from 30 to 60 breaths per minute. Their breathing is often more diaphragmatic and may appear irregular at times. It's important to monitor for any signs of distress, such as wheezing or labored breathing, as these can indicate respiratory issues. Regular pediatric check-ups can help ensure that the infant's respiratory health is on track.
The respiratory system is the system that handles breathing.
