Name the part of the kidney that fits each clue.
- The notch on the inner side, through which the ureter, vessels and nerves pass.
- The funnel shaped space inside the notch.
- The strips of cortex that lie between the medullary pyramids.
- The projections of the funnel into which the tips of the pyramids fit.
- The tough outer covering.
Need a reminder? The key ideaShow
The system has two kidneys, two ureters, a bladder and a urethra. A kidney lies between the last thoracic and the third lumbar vertebra. It has a capsule, an outer cortex and an inner medulla of cone shaped pyramids. The cortex runs between the pyramids as the renal columns. The notch is the hilum, and inside it lies the renal pelvis with its calyces. The kidneys receive to mL of blood a minute, roughly a fifth of the cardiac output.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. (a) The hilum.
Step 2. (b) The renal pelvis.
Step 3. (c) The renal columns, also called the columns of Bertini.
Step 4. (d) The calyces.
Step 5. (e) The capsule.
Answer: (a) hilum; (b) renal pelvis; (c) renal columns; (d) calyces; (e) capsule.
