What is the function of the Meatuses?

The meatuses are passageways or openings within the body, particularly found in the nasal cavity and urinary system. In the nasal cavity, they serve to drain the sinuses and facilitate airflow, enhancing the sense of smell and filtering incoming air. In the urinary system, the meatus refers to the external opening of the urethra, allowing for the passage of urine from the bladder to the outside of the body. Overall, meatuses play crucial roles in drainage, airflow, and the elimination of waste.
