Carefully read each question and provide your answer in the space provided. Refer to your knowledge of kidney anatomy and physiology, and observations from any dissection you may have performed. For questions involving diagrams, label the indicated structures.
1. The outer protective layer of the kidney is called the .
2. The renal cortex is the region of the kidney, located just beneath the capsule.
3. The functional filtering units of the kidney are called .
4. Urine collects in the renal before passing into the ureter.
5. The major blood vessel that brings oxygenated blood to the kidney is the artery.
Refer to the diagram of the kidney cross-section below. Label the indicated structures (A-E).

1. Which part of the kidney contains the renal pyramids and columns?
Renal capsule
Renal cortex
Renal medulla
Renal pelvis
1. The ureter carries urine from the kidney to the bladder.
True
False
1. During the dissection, what was the most prominent difference you observed between the renal cortex and the renal medulla in terms of texture or appearance?
2. Describe the appearance and location of the renal artery and renal vein. How can you distinguish between them visually during a dissection?
3. Explain the path of urine from its formation in the nephrons to its exit from the kidney.
