The inhibited mucus production leads to digestive difficulties. To aid with this, Apollo is prescribed a smooth muscle stimulant to help food move forward by peristalsis. Of course, this has effects in other areas. All of the following regions are affected by the stimulant, leading to increased urination, except: a. ductus deferens.
b. epididymis.
c. urinary bladder.
d. urethra.

B. Epididymis

Explanation:

The region that'll be affected by the smooth muscle stimulant to help food move forward by peristalsis and hence leads to increased urination include the ductus deferens, urinary bladder and the urethra.

It should be noted that the epididymis isn't affected by the stimulant. The epididymis is simply the long, coiled tube which helps in the storage of sperm and then transports it from the testes.

The head of the epididymis is characterized by a thick epithelium which has a long stereocilia and a little smooth muscle. Therefore, the smooth muscle stimulant will not be necessary.
