A

where sperm goes after production to mature
- head
- body
- tail

94
Q

what is the function of the head of the epididymis?

A

connects to vas deferens where sperm travels to the ejaculatory duct

98
Q

what is the function of the vas deferens?

A

begins at the tail of epididymis, ascends to eventually join the duct of the seminal gland to collectively form the ejaculatory duct

99
Q

what is the function of the seminal gland?

A

resides between fundus of bladder and the rectum, secretes fluid rich in fructose and a coagulating agent

100
Q

what is the ejaculatory duct?

A

the combination of the vas deferens and the duct of the seminal gland; joins with urethra to create its distal continuation

101
Q

what is the function of the prostate gland?
