Hm. There is no such thing as the "hilum of the upper lung". The hilum (also called the hilus) is the part of the lung where the bronchi, pulmonary veins, and pulmonary arteries enter the lung. Each lung has its own hilum. Surrounding the hilum are lymph nodes that help drain fluid that has entered the lung. Since the hilum consists of so many different structures with distinct purposes, there's no easy way to discuss how the hilum "works". It's more of an anatomical entity rather than a functional one. Do you have a specific question about the function of one of the structures in the hilum?

The tube connecting the renal hilus of the kidney to the bladder is the ureter. In the renal hilum the ureter, renal blood vessels and nerves enter or exit the kidney.
The lungs.
