The Reproductive System Flashcards
produces reproductive cells in both males (sperm) and females (eggs)
reproductive system
sites of sperm production in a process called spermatogenesis
located outside of the body for temperature regulation
testes
where sperm matures (about 14 days)
epididymus
duct where mature sperm are transported to the urethra
vas deferens
made as sperm travel past the seminal vesicle (fructose), prostate gland (basic substance) and cowper’s gland (mucous)
semen
transports sperm out of the male body
urethra
contains enzymes which penetrate through the egg cell wall
acrosome
contains the chromosomes
nucleus
energy source to move the sperm
mitochondrion
a flagellum to aid in movement
tail
streamlined so it can move quickly
shape
contains about 400000 follicles at puberty
each month about 20 follicles will begin maturation
one follivle will fully mature and release an egg
ovaries
receive the egg from the ovary and sweep it toward the fallopian tubes
fimbriae
tube connecting ovaries to the uterus
where fertilization occurs
fallopian tubes / oviducts
when fertilized egg implants into the fallopian tube
tubal pregnancy/ectopic pregnancy
fertilized egg implants into the uterine wall in the endometrium. it provides nourishment for the developing fetus
uterus
when there is no fertilized egg to implant, the endometrium is shed
menstruation
opening to the uterus
dilates during labour
cervix
canal leading to the uterus
vagina
low levels of hormones cause the endometrium to be shed
menstrual phase (days 1-5)
hormones are released like follicle stimulating hormone
follicular phase (days 1-13)
release by the pituitary to act on the ovaries
gonadotropic hormone
promotes development of about 20 follicles of which 1 will release an egg
follicle stimulating hormone
ovarian hormone
promotes thretaening of the endometrium
estrogen
