Science - Reproductive System Flashcards
what does the penis contain
urethra
what does the urethra do
fills with blood to enable deposition of sperm into vagina
what does the scrotum do
houses tests for spermatogenesis
spermatozoan
MATURE male gametes
what do testes do
produce sperm and testosterone
what are the external structures of the male reproductive system
penis, scrotum, testes
what is the pneumonic to remember external structures of male RS
Please Send Tell
what are the internal structures of the male reproductive system
Epididymis, Vas Deferens, Ejaculatory Duct, Seminal Vesicles, Prostate gland, Bulbourethral
what is the function of the epididymis
stores sperm as they MATURE
What is the function of the vas deferens
transports sperm to urethra
what is the function of the seminal vesicles
secrete alkaline fluid with proteins & mucus
what is the function of the prostate gland
secrete milky white fluid with proteins and & enzymes
what is the function of the bulbourethral
secrete fluid into urethra to neutralize acidity
function of the follicle stimulating hormone (FSH)
stimulates spermatogensis
spermatogenesis
the creation of mature male gametes (mature sperm)
lutenizing hormone function
stimulates testosterone production
what is the function of testosterone
responsible for male sex characteristics
what is an ova
egg cell (female)
what is the function of the fallopian tubes
FERTILIZE, receive sperm, provide safe environment for embryo
labia majora/minora function
protect vagina
bartholins gland function
secrete lubricating fluid
what is the clitoris
erectile tissue
ovaries
female gonads// produce estrogen/ progestorone
what is the canal that carries MATURE eggs to uterus
fallopian tubes
what are the phases of the ovarian cycle
follicular, ovulation, luteal phase
what is the pneumonic to remember ovarian cycle
Fuck You Linda
What happens during the Follicular phase during the ovarian cycle
FSH (follicle stimulating hormone) stimulates mature follicle, secrete estrogen (helps rejuvinate uterine lining)
what happens during the ovulation phase of the ovarian cycle
Releases oocyte, Lutenizing Hormone (LH) –> release progesterone
what happens during the luteal phase of the ovarian cycle
forms corpus luteum
what happens if their is no egg during the luteal phase
corpus luteum regresses
what is an oocyte
immature egg
what does the corpus luteum do
releases progesterone, help uterine lining
what are the phases of the uterine cycle
Proliferative phase, secretory phase
what happens during the proliferative phase of the uterine cycle
regenerate uterine lining
what happens during the secretory phase of the uterine cycle
endometrium increaseses in vascularity, nutrients secreted, preps for implantation
what happens during the secretory phase without implantation
endmetrium sheds –> menstration
what happens during pregnancy
blastocyst implants to uterine lining, increase progesterone, increase estrogen
what happens during partuition
increase glucocorticoids, Oxytocin and Estrogen –> increase uterine contraction
what does glucocorticoids do
increase estrogen, decrease progesterone
prolactin
stimulates production of milk
