They appear in tubulo-acinar arrangements in submucosal glands. Tracheobronchial serous cells play a vital role in maintaining respiratory health by secreting serous fluid, which is rich in enzymes, ions, and antimicrobial proteins. This serous fluid is essential in clearing out debris, trapping and neutralizing inhaled pathogens and particulate matters, thereby helping in preventing infections. Their secretory products also include water and electrolytes that, combined with mucus (from mucous cells), maintain proper humidity within the airway and lubricate its surfaces, facilitating unhindered airflow. Dysfunction of these cells may lead to diseases such as cystic fibrosis.
