The Aorta and the Vena Cava
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.
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.
AOrta
The testicular arteries, which leave the aorta just below the renal arteries (that supply the kidneys).
foramen
They enter and leave on the or at the superior border.
Capillaries. they have such thin walls that substances can easily diffuse through them.
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.
Pulmonary arteries.
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.
