Bronchic cells are specialized cells found within the bronchi, which are the large airways in the respiratory system that branch off from the trachea. These cells are primarily responsible for producing and secreting mucus that helps to protect and lubricate the airways.
The bronchic cells, also known as goblet cells, are characterized by their unique shape and structure. They have a narrow base that sits on top of the basement membrane, which provides support to the bronchi. From the base, the cells widen and form a goblet-like shape, with the widest part of the cell containing the nucleus.
These cells play a crucial role in maintaining the health and function of the respiratory system. They secrete mucus, a sticky substance that traps foreign particles such as dust, dirt, and pathogens that are inhaled with the air. The mucus also helps to moisten and humidify the air, making it easier for the airways to transport oxygen to the lungs.
When an irritant or foreign particle is detected in the airways, the bronchic cells increase their mucus production to facilitate the removal of these substances through coughing or sneezing. This protective mechanism helps to prevent infections and maintain the integrity of the respiratory system.
In summary, bronchic cells or goblet cells are specialized cells within the bronchi that secrete mucus to protect and lubricate the airways, aiding in the removal of foreign particles and maintaining the health of the respiratory system.
