EXAM 3 2-2 Flashcards
Testes
Production of sperm (by
meiosis) and male sex hormone
(testosterone)
Seminiferous tubules
Area in testes where sperm are
produced
Epididymis
Where sperm mature and are
stored
Accessory glands (prostate,
seminal vesicles, and
bulbourethral glands)
Produce lubricant for sperm
Vas deferens
Tube that carries sperm
from epididymis to urethra
Urethra
Tube that carries urine from urinary bladder to outside; also carries semen during ejaculation
Penis
External genital organ; urination, and allows for transfer of semen to female vagina
Ovary
Production of eggs/ova (by meiosis) and female sex hormones (estrogen and
progesterone)
Ovarian follicles
(inside ovary)
Cluster of cells that protect and nourish developing eggs in the ovary; produces estrogen
Corpus luteum
(also inside ovary)
Mass of follicle cells that develops in ovary after ovulation; produces progesterone
Oviduct (fallopian tube)
Tube that carries ovum
from ovary to uterus
Uterus
Site of embryo
implantation and fetal
development
Cervix
Constriction around lower
portion of uterus; opens
into vagina
Vagina
Muscular tube that
receives sperm; also serves
as birth canal
What does each of these hormones do in the male reproductive system?
a. FSH
b. LH
c. Testosterone
- FSH stimulates cells in the testes, which help sperm to develop
- LH stimulates other cells in the testes; these release
testosterone
Testosterone has two effects:
* It promotes the formation of new sperm (lots!)
* leads to the development of secondary male sex characteristics (more body hair, deeper voice, sex drive)
What does each of these hormones do in the female reproductive system?
a. FSH
b. LH
FSH - maturation of ovum and
development of secondary sex characteristics
(breast enlargement, additional body fat)
LH - ovulation (release of the ovum) and
secretion of progesterone (to prepare for
pregnancy)
What does “ovulation” mean, and where does it occur?
release of the ovum/ in the ovary
What is the endometrium, and why is it important in the uterine cycle?
thickening of the inner walls of the uterus -> for the cycle
What is HCG, and what does it tell us?
Hormone detected in pregnancy test
vasectomy
cutting the vas deferens
Name three (3) common sexually transmitted diseases that can be treated successfully with
antibiotics.
chlamydia, gonorrhoea and syphilis
What is the best approach to preventing cervical cancer caused by human papilloma virus
(HPV)?
Vaccine
