female reproductive system Flashcards
(21 cards)
tube that gets the egg from the ovary to the fallopian tubes:
frimbrae + infundibulum
tube that carries the egg from the ovary to the uterus
fallopion tube
nutures and supports fertilized egg
uterus
where egg impants
endometrium
where the muscles contract in labor and allow for the stomach and uterus to stretch during pregnancy
myometrium
passagway into the uterus: expands for birth to happen
cervix
releases hormones and produces eggs
ovaries
birth canal, allows for mentrusal flow and it is the passage for sexual intercourse
vagina
what occurs in the uterus during days 1-7
menstrual phase
lining of uterus is shed (endometrium is shed)
what occurs in the uterus during days 7-14
the endometrium begins to rebuild itself and thicken
what occurs in the uterus during days 14-28
the endometrium becomes thicker and get enhanced
what occurs in the ovaries during days 1-13
follicular phase: several follicles in the ovary begin to mature by typically one becomes dominant, which gets prepared to release an egg
what occurs in the ovaries during day 14
Ovulation: mature follicle ruptures and releases an egg into the fallopian tube, most fertile day of the cycle
what occurs in the ovaries during days 15-28
the ruptured follicle becomes the corpus luteum, which secretes progesterone
importances of LH in the female reproductive system and where they are produced
pituitary gland:
triggers ovulation and stimulates the formation of the corpus luteum which produces progesterone
importances of FSH in the female reproductive system and where they are produced
Pituitary gland:
stimulates follicle development in their ovary during follicular phase
supports the maturation of eggs within the follicles
promotes estrogen production
importances of estrogen in the female reproductive system and where they are produced
Ovary:
stimulates thickening of uterine lining during the first half of the cycle
plays key role is secondary sex characteristics (breast development, body shape)
importances of progesterone in the female reproductive system and where they are produced
Ovary:
maintains uterine lining for possible inplantation of. a fertilized egg
when does oogenesis occur in females?
before birth
during puberty to menopause occcurs each month when egg is released
what is the difference between oogenesis in females and spermatogenesis in males ?
oogenesis:
before birth
ends at menopause
one mature egg per cycle
400-500 mature eggs in a lifetime
spermatogenesis:
starts at puberty
continues throughout lifetime
millions of sperm daily
billions of sperm over a lifetime
what is menopause and when does it typically occur?
the ending of a woman’s reproductive years
occurs around ages 40-50
