Internal structure of the Kidney !!
So we're looking here at the two kidneys and you can see the abdominal aorta and the inferior vena cava giving off the renal artery and renal veins to the kidney. You can see the ureters coming out of the kidney. So the place where these structures enter the kidney is called the hilum. This is a vertical slit on the medial aspect of the kidneys where the various structures enter the kidneys. So you've got blood vessels, the ureter, lymphatics and the nerves which enter the kidney at the hilum. So for the rest of this tutorial, I'm going to switch over to a cross-section and talk you through some of the internal features of the kidney. So, let's just imagine take a slice through the kidney in this plane. We're looking here at a section of the left kidney. The area where these structures enter is the hilum as I mentioned. The hilum continues as the renal sinus inside the kidney. The renal sinus contains all these structures that enter into and out of the kidney. So ...
