The point of entry for bronchi, vessels, and nerves into each lung is called the hilum.

The hilum is a crucial anatomical feature as it is the area where structures such as the mainstem bronchi, pulmonary arteries, pulmonary veins, lymphatics, and various nerves enter and exit the lungs. It provides a passage for these vital components to connect the lungs with the rest of the body, facilitating essential functions such as gas exchange, blood circulation, and neural regulation. Understanding the anatomy of the hilum is important in fields such as medicine, particularly in pulmonology and thoracic surgery, as it is often involved in various medical conditions and procedures.
