Urinary System

	Picture of sectioned kidney. You should be able to identify the ureter, the renal artery and vein, the interlobar arteries and veins, and see the remnants of the arcuate arteries. You should be able to distinguish between the medulla and the cortex. Within the medulla, you can see the renal pyramids, the papillae, the calyx at the tip of each papilla, and the renal pelvis.
	In this picture, you can clearly see the interlobar veins running through the renal columns. You cal also see some of the interlobar arteries.
	Model of the kidney. You should be able to identify all the structures you saw on the dissected kidney. You should also be able to identify the nephrons on this model.
	Model of the beginning of the nephron. You should be able to identify the glomerulus and the Bowman's capsule.
	Model of the urinary system. You should be able to identify the renal arteries and veins, the kidneys (and the various parts of the kidneys), the ureters and the urinary bladder.
	Here is an additional model that includes the kidney as well as a model of the nephron and bowman's capsule/glomerulus.
	This shows the torso model with the urinary system exposed.
