The first slide shows the kidney medulla. This creates and maintains the osmotic gradient which is important for concentrating urine and reabsorbing water. It comprises of renal pyramids, U-shaped tubule called the loop of Henle, collecting ducts that pass through the renal medulla, and vasa recta surrounding the nephron loops.
The second slide is the ureter. This is the tube that transports urine from the renal pelvis to the bladder. It is composed of the mucosa made of transitional epithelium and lamina propria, muscularis made of an inner and outer longitudinal layer and a middle circular layer, and the adventitia made of connective tissue, blood vessels, lymphatics, and nerves.
