Reproduction and Development Questions
1. What are the primary functions of the male reproductive system? To produce sperm and
deposit them in the female reproductive tract.
2. How does the location of the scrotum affect sperm? The scrotum holds the testes
outside the body at a temperature about 2 -4 degrees lower than body
temperature. Sperm develop best at a lower temperature.
3. Where does meiosis occur in the male reproductive system? Testes
Order the steps in the formation and transportation of sperm from 1 to 6.
______4______4. Mature sperm enter the vas deferens.
______2______5. Newly formed haploid sperm cells pass through a series of coiled ducts to
the epididymis.
______6______6. Sperm leave the body via the urethra.
______3______7. Sperm mature in the epididymis.
______1______8. Cells lining tubules in the testes undergo meiosis.
______5______9. Sperm travel along the ejaculatory ducts and into the urethra.
If the statement is true, write true. If it is not, rewrite the italicized part to make it true.
10. As is the case in human males, a woman ’s hypothalamus produces FSH and LH.
False - Pituitary
11. FSH stimulates follicle development and the release of estrogen from the ovary.
True
12. In females, luteinizing hormone (LH) is responsible for the development of the secondary sex
characteristics.
False - estrogen
13. Long before a woman is born, cells in her ovaries that are destined to become future eggs
undergo several mitotic divisions .
True – as the ovaries are developing they produce more
oogonium cells through mitosis. After the ovaries are formed, the
process stops and no more egg producing cells are made.
fertilization
Implantation
zygote
Blastocyst
oviduct
Label the diagram. Use these
choices: ovary, implantation,
blastocyst, ovulation, fertilization,
uterus, zygote, vagina, oviduct.
ovulation
Ovary
Uterus
vagina
Place each of the terms below under the correct reproductive system in the table. Then explain the
role that each term plays in the reproductive system.
bulbourethral gland
follicle
corpus luteum
prostate gland
semen
vagina
cervix
epididymis
Male System
Function
bulbourethral
gland
Semen
seminal
vesicle
Produce nutrient rich seminal
fluid and lubricant
Combination of sperm and
seminal fluid for fertilization
Gland that secretes seminal
fluid
prostate
gland
Provides most of the fluid for
semen and pH buffer
corpus
luteum
epididymis
Storage and maturation of
sperm
Pocket of skin that holds testes
at a lower temperature
Tube that carries sperm from
epididymis to urethra
vagina
scrotum
vas deferens
oviduct
scrotum
seminal vesicle
vas deferens
Female
System
follicle
Function
cervix
Lower end of uterus that controls
movement into/out of vagina
Tube between ovary and uterus
that carries eggs and where
fertilization occurs
Cells of ruptured follicle produce progesterone after
ovulation
Birth canal, passage for secretions
from uterus, accepts sperm
oviduct
Helps egg mature
Use each of the terms below just once to complete the passage.
amnion
blastocyst
chorion
chorionic villi
embryo
placenta
umbilical cord
zygote
implants
oviduct
Usually in the upper part of a(n) ____oviduct ____ an egg and one sperm unite
to form a(n) __zygote _______________.This single cell divides repeatedly to form a(n)
_blastocyst____________,which __implants___________in the uterine wall. Part
of the blastocyst becomes the ____embryo______,which is surrounded by a fluid-filled,
membranous sac called the ________amnion________. The embryo is connected to the wall of the
uterus by its ________ umbilical cord________.The amniotic sac is enclosed by the
_____chorion________,which later forms the _____ chorionic villi ________
Nutrients and oxygen from the mother and wastes from the embryo are exchanged at the
_____placenta_______.
