All bones have foramen in them. These are canals or openings through which nerves and blood vessels go.
Blood vessels, nerves, lymphatic vessels, and the ureter enter and leave through the hilum of the kidney.
The hilum is the part of the organ where vessels and nerves enter and leave.For most organs vessels and nerves enter an leave all over the place and not always near each other. However in the kidneys and lungs the major blood vessels enter at an area called the hilum.
foramen
A nutrient foramen is an opening in a bone through which blood vessels and nerves enter and exit to supply the surrounding tissues with nutrients and sensation. These openings are crucial for maintaining the health and function of bones by allowing for appropriate blood supply and nerve communication.
The part of the kidney that serves as a passageway for nerves and vessels to enter and leave is called the hilum. It is located on the medial surface of the kidney and serves as the entry and exit point for the renal artery, renal vein, ureter, and various nerves. This area is crucial for the kidney's blood supply and nerve function.
The root of the lung is connected to the hilum, which is a region where blood vessels, nerves, and bronchi enter and exit the lung. The root of the lung serves as a pathway for these structures to enter and leave the lung.
The Aorta and the Vena Cava
AOrta
on the concave side of the kidney , which faces the vertebral column, lies a depressin called Hilus. it provides a placefr the renal vessels, nerves and the ureter to enter or leave the kidney.
