Reproductive System Deck Flashcards
organs of the male reproductive system
the testes, seminal vesicles, seminal ducts, prostate gland, Cowper’s glands, the penis
male gonads
the testes
testes
produce sperm
sperm
the male sex cells
function of testosterone
to help the sperm to mature
testosterone
causes secondary male sex characteristics to appear (ex.: the growth of facial hair, an increase in the size of muscles, the deepening of the voice)
the testes are suspended outside of the body
low temperature is needed for the sperm to develop safely
location of the epididymis
at the top part of the testis
epididymis
stores sperm until they become mature or motile
vas deferens
(ductus deferens) connects with the epididymis; act as a passageway and temporary storage area for sperm
seminal vesicles
each seminal vesicle adds fluid rich in sugar that nourishes the sperm
semen
the term for the fluid rich in sugar that nourishes the sperm that is thick, yellow fluid and the sperm together
ejaculatory ducts
two short tubes formed when the vas deferens and the seminal vesicles join
location of the prostate gland
below the urinary bladder
function of the prostate gland
to secrete a fluid that neutralizes acidity in the surroundings
fluid secreted by the prostate gland
serves to both protect the sperm and help them to move
location of the Cowper’s glands
two small glands located below the prostate
function of the Cowper’s (bulbourethral) glands
to secrete a fluid that neutralizes acidity in the surroundings to help sperm survive and to secrete fluid that lubricates the inside of the urethra to help the semen move more easily
function of the penis
to, as the male organ for intercourse, deposit semen into the female vagina
organs associated with the female reproductive system
the ovaries, fallopian tubes, uterus, vagina, vulva, breasts
female gonads
ovaries
production of the ovaries
ova
ova
the female sex cells
ovulation
the process by which about every 28 days, a single ovum matures and the follicle it is in breaks open to release it
each ovary
contains thousands of small sacs called follicles where immature ova are stored
function of estrogen and progesterone
to help with the development of the female reproductive organs and to cause secondary female sex characteristics to appear (ex.: the enlargement of the breasts, the broadening of the hips, the growth of pubic hair)
location of the fallopian tubes
above the ovaries but are not directly connected to them
function of the fallopian tubes
to be the usual location of fertilization
fertilization
when an ovum and a sperm join to create new life
after ovulation
the ovum is swept into one of the two fallopian tubes by fingerlike projections called fimbriae
peristalsis
muscle contractions that move the ovum to the uterus
cilia
tiny hairs that line the tubes and also help guide the ovum to the uterus
uterus
a hollow, pear-shaped, and highly muscular organ that lies behind the urinary bladder and in front of the rectum
function of the uterus
to provide for the development and growth of the fetus if pregnancy occurs
three layers of the uterine wall
the endometrium, the myometrium, the perimetrium
endometrium
the innermost layer of the uterine wall
myometrium
the middle layer of the uterine wall
perimetrium
the outermost layer of the uterine wall
endometrium
contains a thick lining of blood tissues
if a fertilized ovum implants on its surface (endometrium)
will nourish the developing fetus
