You can continue to test your knowledge of the pathway followed by the sperm by clicking on the black numbers.
The black arrow indicates the point at which the ducts carrying the sperm pass into the body cavity. Note how the ducts from both sides loop toward the midline and join under structures (2) & (3).
Numbers shown in red are part of the urinary system. The ureter (1) carries urine from the kidney to the bladder (2). From the bladder urine is carried in the urethra (3). At the level of the prostate gland (1) the urethra joins with the ductus deferens and urine follows the same pathway as the sperm. It leaves the system at the urogenital aperture at the tip of the glans penis (7).
