 We have held up the right kidney This is the renal vein and you can see it's coming from the inferior vena cava here And this is a branch of the renal artery in this particular cadaver We have not one but two renal arteries and we can see one renal artery here And we can see the other renal artery behind that here So we can see two renal arteries Let's take a look at the distribution of the renal artery inside the kidney This first branch which we have lifted up we can see it is dividing into a lower one and an upper one These are called segmental arteries So this is the anterior superior segmental artery. This is the anterior inferior segmental artery Turn the kidney and you can see the other renal artery and we can see the multiple branches going into the hyalum One branch here another branch here and a third branch here So these are the other three segmental arteries. So therefore each kidney receives five segmental arteries anterior superior anterior inferior Polar superior polar inferior and posterior So these are the five segmental arteries They're all arising from the abdominal aorta. Now we are looking at the pedicle of the left kidney Straight away I would like you to notice that this is the left renal vein and can you see the left renal vein is much longer than the Right renal vein because it is coming from the inferior vena cava, which is on the right side and Left renal vein is superficial to the renal artery Now we will take a look at the renal artery here. Also, we can see that there are not one but two renal arteries this is one renal artery and Just behind that is the other renal artery. I've lifted up both the renal arteries We can see both the renal arteries here Let's take the first one here. Also, we can see it is dividing into and and an upper division and a lower division So this is respectively the anterior superior and anterior inferior and this is the posterior Half of the renal artery and that also is dividing into three branches One two three. So therefore here also we have five segmental arteries this space Where my finger has gone in this is referred to as the renal sinus and The renal sinus is the space between the anterior and the posterior layers of the kidney and what does it contain? It contains four things the branches of the renal artery the divisions of the renal vein Fat a little bit of which we can see here and the pelvic alicea system So this is what we wanted to show you in the high level of the kidney
