    In this lecture we are going to look at the kidneys and the suprarenal glands. So we will start off by looking at the position of the kidneys and the superarenal glands and how that position is measured on to the surface of the abdomen. We will then explore their gross anatomy by looking at the position within the abdomen and their relations to other organs. We will look at the kidney segments and their specific blood supply. We will then look at the internal structure of the kidney and the suprarenal glands. Look how the renal pelvis is formed and that gives rise to the ureters and we will look at few constrictions that they have along their course. We will then look at the suprarenal gland vasculature because that can be quite complex. So the kidneys are paired retroperitoneal organs located against the posterior abdominal wall. And they are really important in removing excess water, salts and waste products from the body. They are important in that they maintain the correct balance of nutrients and chemicals. So maintaining homeostasis, the internal environment. The suprarenal glands also play an important role and that's in supporting the blood pressure and releasing adrenaline. We will explore that through this lecture. So let's have a look at the surface anatomy of the kidneys and the suprarenal glands. Well here, the best way to view the kidneys is posteriorly. As they are located against the posterior abdominal wall either side of the lumbar vertebrae really extending from T12 and L3 extending down from about T12 to L3. And we can see that its sitting against ribs 11 and 12. So if someone was to damage the ribs, they could then puncture the kidneys. So we can see where the two kidneys are positioned....
