Reproductive System Flashcards
(31 cards)
what is the function of the male reproductive system?
to produce and transfer sperm and semen into the female reproductive tract and secrete male hormones
what does the external structure of the male reproductive system include?
penis, scrotum, testes
the penis contains the _____
urethra
scrotum
sac of skin and smooth muscle that houses the testes and keeps them at a proper temperature for spermatogenesis
testes
AKA testicles, are the male gonads which produces sperm and testosterone
what does the internal structure of the male reproductive system include? (7 things)
epididymis, vas defrens, ejaculatory ducts, urethra, seminal vesicles, prostate gland, bulbouretheral glands
epididymis
stores the sperm as it matures
what is sperms pathway?
epididymis > vas deferens > ejaculatory duct
seminal vesicles
secrete alkaline fluids with proteins and mucus into the ejaculatory duct
prostate gland
secretes milky white fluid with proteins and enzymes as part of the semen
bubourethral glands
AKA Cowper’s glands, secrete a fluid into the urethra to neutralize acidity in the urethra
what are the 3 hormones associated w the male reproductive system and what are they for?
- follicle stimulating hormone: stimulates spermatogenesis
- luteinizing hormone: stimulates testosterone production
- testosterone: responsible for male sex characteristics
what is the function of the female reproductive system?
to produce ova (egg cells) and transfer them to fallopian tubes for fertilization. the ova then receive sperm from the male and protect a nourishing environment for the developing embryo
what does the external portion of the female reproductive system include?
labia majora, labia minora, Bartholin’s glands, clitoris
Bartholin’s glands
secrete a lubricating fluid
what does the internal portion of the female reproductive system include?
ovaries, fallopian tubes, uterus, vagina
ovaries
female gonads, produce ova and secrete estrogen and progesterone
fallopian tubes
carry mature egg toward the uterus. where fertilization occurs
uterus
where the fertilized egg implants into the uterine wall
the female reproductive cycle is characterized by what 2 things?
changes in ovaries and uterine lining (endometrium)
what are the 3 phases of the ovarian cycle?
- follicular phase
- ovulation
- luteal phase
follicular phase
FSH stimulates the maturation of the follicle > follicle secretes estrogen > estrogen helps regenerate uterine lining that was shed during menstration
ovulation
the release of a secondary oocyte from the ovary. induced by a surge in LH
luteal phase
begins w formation of corpus luteum from remnants of the follicle > corpus luteum secretes progesterone and estrogen, which inhibit LH and FSH > progesterone maintains the thickness of the endometrium > if a fertilized egg is not implanted, corpus luteum begins to digress and estrogen and progesterone levels drop > FSH and LH are no longer inhibited > cycle renews
