What is the Role of Histology in the Respiratory System?
The respiratory system comprises structures like the trachea, bronchi, and lungs. Histological examination reveals the presence of ciliated epithelial cells in the trachea, which help in trapping and expelling particles. In the lungs, the alveoli's thin epithelial lining facilitates gas exchange, a process that histology helps elucidate in great detail.
