hilus

The hollow or concave side of the kidneys is turned inwards, and the deep fissure of this side, known as the hilus, widens out to form the pelvis.

Notice that all the vessels leave and enter the kidney at the hilus.

Observe that its shape is something like that of a bean, and note that the concave part (hilus), when in its normal position, is turned towards the backbone.

A Practical Physiology Albert F. Blaisdell

Through the hilus the renal artery passes into each kidney, and from each hilus passes outwards the renal vein, a branch of the inferior vena cava.

Little or no anastomosis occurs between the superficial and deep lymphatics of the lungs, except in the region of the hilus.

These are preganglionic fibers of the sympathetic system and terminate in the submaxillary ganglion and small ganglia in the hilus of the submaxillary gland.

Instead of entering the kidney at the hilus, they usually pierce the upper or lower part of the gland.

Behind the hilus and pulmonary ligament is a vertical furrow produced by the descending aorta, and in front of this, near the base of the lung, the lower part of the esophagus causes a shallow impression.

XI. Splanchnology. 1e. The Lungs 1918

Before reaching the hilus of the kidney, each artery divides into four or five branches; the greater number of these lie between the renal vein and ureter, the vein being in front, the ureter behind, but one or more branches are usually situated behind the ureter.

The superficial efferents turn around the borders of the lungs and the margins of their fissures, and converge to end in some glands situated at the hilus; the deep efferents are conducted to the hilus along the pulmonary vessels and bronchi, and end in the tracheobronchial glands.
