Renal anatomy

3. A fibrous layer surrounding the kidney for protection.
5. Cone-shaped structures containing nephron loops and collecting ducts.
7. Functional units responsible for filtration and urine formation.
10. Cup-like structures collecting urine from renal pyramids.
11. A tube that transports urine from the bladder to the outside. It is longer in males (~20 cm) than in females (~4 cm).
12. A U-shaped structure with descending and ascending limbs, concentrating urine.
13. A funnel-shaped structure collecting urine before passing into the ureter.
14. The inner layer consisting of renal pyramids.

1. A hollow, muscular organ that stores urine until excretion.
2. A cup-like structure surrounding the glomerulus, collecting the filtrate.
4. Muscular tubes (25–30 cm long) carrying urine from the kidneys to the bladder via peristalsis.
6. The outer layer containing glomeruli and nephron tubules.
8. The entry/exit site for the renal artery, vein, and ureter.
9. A capillary network within Bowman's capsule where blood filtration occurs.
10. Receives filtrate from multiple nephrons and channels it to the renal pelvis.
