BIO 30 REPRODUCTIVE SYSTEMS EXAM
SCRIPT FULL QUESTIONS AND CORRECT
ANSWERS DETAILED REVIEW SHEET
●● Where are sperm cells produced within the testes?
Answer: In the seminiferous tubules.
●● What is the function of the epididymis?
Answer: It is the site for the maturation and storage of sperm.
●● Which tubes conduct sperm from the epididymis to the ejaculatory
duct?
Answer: The vas deferens.
●● What substances do the seminal vesicles contribute to semen?
Answer: Fructose (as a food source for sperm) and prostaglandins (to
signal the female uterine system to contract).
●● What is the role of the prostate gland in the male reproductive
system?
Answer: It secretes a milky, alkaline fluid containing sodium
bicarbonate to neutralize the acidic environment of the vagina and aid in
sperm motility.
,●● What is the function of Cowper's (bulbourethral) gland?
Answer: It secretes a mucus-rich fluid for lubrication and to neutralize
acidic urine residue in the urethra prior to ejaculation.
●● What hormone stimulates the interstitial cells in the testes to produce
testosterone?
Answer: ICSH (Interstitial Cell Stimulating Hormone), also known as
LH (Luteinizing Hormone).
●● What is the role of FSH in the male reproductive system?
Answer: It influences the seminiferous tubules to promote sperm
production.
●● What is the function of the acrosome cap on a sperm cell?
Answer: It contains enzymes that assist the sperm in penetrating the egg.
●● What is the purpose of the mitochondria located in the midpiece of a
sperm cell?
Answer: To provide energy for the sperm's movement (motility).
●● Where does fertilization normally occur in the female reproductive
system?
Answer: In the oviducts (fallopian tubes).
,●● What is the primary function of the uterus?
Answer: It is the site where a fertilized ovum implants and where the
embryo and fetus develop.
●● What are the three layers of the uterus?
Answer: The perimetrium (outer), myometrium (muscle), and the
endometrium (inner mucus membrane).
●● What is the function of the cervix?
Answer: It is a narrow muscular opening at the end of the uterus that
secretes mucus and holds the baby during pregnancy.
●● What is the role of the ovaries?
Answer: They produce egg cells (ova) and secrete the hormones
estrogen and progesterone.
●● What is the corpus luteum and what is its function?
Answer: It is a structure formed in the ovary after ovulation that secretes
progesterone and estrogen to maintain the endometrium during early
pregnancy.
●● What does GnRH (Gonadotropin-releasing hormone) trigger in the
pituitary gland?
, Answer: It triggers the release of FSH and LH (or ICSH).
●● What is the function of estrogen in the female reproductive cycle?
Answer: It promotes secondary sex characteristics and thickens the
endometrium.
●● What is the function of progesterone in the female reproductive
cycle?
Answer: It maintains the endometrium and inhibits ovulation.
●● What is the significance of the vagina's acidity?
Answer: It acts as a protective mechanism, though it is more acidic
during low-fertility periods of the month.
●● What happens to the arterioles and venules in the penis during an
erection?
Answer: Arterioles dilate to increase blood flow, while venules constrict
to trap blood, increasing blood pressure.
●● What is the term for the removal of the foreskin (prepuce)?
Answer: Circumcision.
●● What is the primary difference between the male and female urethra
regarding function?
