What does the epididymis do?
the epididymis provides a reservoir for storage, maturation, and transport of sperm
The _____________, a cordlike structure, begins at the tail of the epididymis
vas deferens

inguinal canal
The exterior opening of the tunnel is the ___________________; the internal opening of the canal is the ______________________
external inguinal ring; internal inguinal ring
What is an indirect inguinal hernia?
develop at the INTERNAL inguinal ring, where the spermatic cord exits the abdomen
What is a direct inguinal hernia?
they arise more medially from weakness in the floor of the inguinal canal and are associated with straining and heavy lifting, it is found at the EXTERNAL inguinal ring
