Now, let's review what we've seen of the structures of the urinary system.
Here's the renal cortex, and medulla. Here's the hilum of the kidney, the renal pelvis, the ureter, the renal sinus, two calyces, and two renal papillae. Here are the suprarenal glands, the suprarenal cortex, and medulla.
Here's the ureter again. Here's the bladder, the prostate the ureteric ostia, and the internal urethral meatus. Here's the ampulla, and the seminal vesicle.
In the female, here are the bladder, and the urethra, with the internal, and external urethral meatus.
