Mitosis vs. Meiosis:-correct-answer-Mitosis: one division forming 2 identical cells
(clones) with 46 chromosomes; Meiosis: two divisions forming 4 genetically
different cells with 23 chromosomes
Zygote:-correct-answer-fertilized egg
True or false: females produce about 2-3 polar bodies to one viable gamete
(ovum) with 23 chromosomes:-correct-answer-True
Female reproductive hormones:-correct-answer-FSH, LH, estrogen, progesterone
menstrual phase:-correct-answer-days 1-5, all but innermost layer of uterus is
shed

Describe the structure and function of the testes.:-correct-answer-have the
function of sperm and testosterone production. Testosterone is a hormone
produced by the interstitial cells inside the connective tissues. Each testis has
hundreds of lobules and each lobule contains several seminiferous tubules where
the site of sperm production takes place.
Where is the site of sperm maturation?:-correct-answer-epididymis
What would happen if the testes do not descend into the scrotum?:-correct-
answer-sterility, If the testes do not descend into the scrotum, gametes may not
be produced because sperm production requires an environment cooler than
body temperature.
What is the length of sperm maturation? Why?:-correct-answer-Maturation for
about 20 days is required for the sperm to gain the ability to swim.
What is the site where the vas deferens enters the abdomen?:-correct-answer-
travels through superior inguinal canal
What is the ejaculatory duct?:-correct-answer-Joining of the vas deferens and
seminal vesicle duct that opens into the urethra
, 3|Page
What is a vasectomy?:-correct-answer-cutting of the vas deferens
The fluids of the semen are contributed by what three glands?:-correct-answer-
The seminal vesicles, the prostate and the bulbourethral glands
What is semen?:-correct-answer-A thick, whitish fluid that contains sperm and
accessory gland secretions
Discuss the function of the antibiotics found in semen.:-correct-answer-It kills any
bacteria in the male urethra or female reproductive system which would kill the
sperm to kill any bacteria in the urethra which would kill the sperm.
What do the seminal vesicles contribute to the contents of semen?:-correct-
answer-these secrete a thick, viscous fluid containing nutrients (fructose, vitamin
C, and prostaglandins) for use by the sperm.
