MICROANATOMY

Detailed explanation-1: -The bronchus in the lungs are lined with hair-like projections called cilia that move microbes and debris up and out of the airways. Scattered throughout the cilia are goblet cells that secrete mucus which helps protect the lining of the bronchus and trap microorganisms.

Detailed explanation-2: -Cilia are the tiny, hair-like structures that line the airways in the lungs. They are designed to protect the airways and help move away any excess mucus.

Detailed explanation-3: -The cilia are specialized organelles that beat in metachronal waves to propel pathogens and inhaled particles trapped in the mucous layer out of the airways.

Detailed explanation-4: -Cilia are mobile, tiny, finger-like projections on the surface of airway cells. Cilia line the airways and help move mucus up and out of the lungs [5].
