MICROANATOMY

Detailed explanation-1: -In the trachea’s inner layer, you have small, hair-like structures called cilia. Cilia move in rhythm to push mucus out of your trachea so that you either expel or swallow it. Between each ring of cartilage in your trachea, you have a muscle called the trachealis.

Detailed explanation-2: -Cilia are complex structures of the paranasal sinus mucosa in which its function is critical to respiratory defense. Cilia beat in a coordinated manner to clear the paranasal sinus cavities and upper airway of the mucus blanket that contains the pathogens and debris that are continually inspired in normal respiration.

Detailed explanation-3: -The mucus traps smaller particles like pollen or smoke. Hairlike structures called cilia line the mucous membrane and move the particles trapped in the mucus out of the nose. Inhaled air is moistened, warmed, and cleansed by the tissue that lines the nasal cavity.

Detailed explanation-4: -The respiratory system includes the nose, mouth, throat, voice box, windpipe, and lungs.

Detailed explanation-5: -Respiratory epithelium is ciliated pseudostratified columnar epithelium found lining most of the respiratory tract; it is not present in the larynx or pharynx.
