Answer to Question 1

ANS: D
The anal canal is the outlet for the gastrointestinal tract and is approximately 3.8 cm long in the adult. It is lined with a modified skin that does not contain hair or sebaceous glands, and it slants forward toward the umbilicus.

Answer to Question 2

ANS: A, D
Prostate cancer is typically detected by testing the blood for PSA or by a DRE. It is recommended that both PSA and DRE be offered to men annually, beginning at age 50 years. If the PSA is elevated, then further laboratory work or a transrectal ultrasound (TRUS) and biopsy may be recommended.
