Nasal and oral Cavities
lined with mucus and cilia, airs swirls through nasal conchae
The nasal and oral cavities are part of the respiratory system where air passes through as it enters and exits the body.
The nasal cavity, located in the upper part of the respiratory system, is lined with tiny hairs called cilia and mucus membranes. These hairs and mucus help filter out dust, pollen, and other particles present in the air we breathe. Additionally, the nasal cavity warms and moisturizes the air before it reaches the lungs.
The oral cavity, also known as the mouth, is located below the nasal cavity and is responsible for a number of functions in the digestive and respiratory systems. When air passes through the oral cavity, it first encounters the tongue, which helps move food and drinks and also contains taste buds. The oral cavity also contains the tonsils, which help trap bacteria and viruses, and the uvula, which helps close off the nasal cavity during swallowing to prevent food or drinks from entering the lungs.
Both the nasal and oral cavities are important structures in the respiratory system that help ensure proper air intake and filtration.
