intro to reproductive system Flashcards
compare and contrast the male and female reproductive systems
like cells and where they go and shit
female
- fetal cells give rise to glands that produce sex hormones
- cells remain in abdomen and develop into ovaries
- responds to follicle stimulating hormone (FSH) and luteinizing hormone (LH)
male
- fetal cells give rise to glands that produce sex hormones
- cells migrate from abdomen to produce testes
- respond to follicle stimulating hormone (FSH) and luteinizing hormone (LH)
female reproductive system
name some structures of the female reproductive system
- two ovaries (produce and release ovum)
- two fallopian tubes (ovum rides these guys to the uterus)
- uterus (ovum waits here to be some sperm)
- accessory structures include vagina, clitoris, labia, and breast tissue
female reproductive system
what are the two hormones that stimulate and mainatin female reproductive structures
- estrogen
- progesterone
primary goal is to prepare for preganancy and maintain pregnancy
female reproductive system
describe estrogen
- effects are notices at the menarche
- female charcetristics are associated with the effects of estrogen
- produced by the ovaries
female reproductive system
describe progesterone
- released after ovulation
- helps support the development of a fetus
- effects on body temp to indicate ovulation
female reproductive system
describe puberty in females
the beginning of sexual development, usually occurs ages 7-13
female reproductive system
describe GnRH
- gonadotropin-releasing hormone
- not released during childhood
- stimulates the anterior pituitary to release FSH and LH
female reproductive system
when estrogen rises in blood, what happens?
causes LH surge -> follicle bursts -> ovulation
female reproductive system
what is ovulation
the release of an ovum from the follicle
male reproductive system
name some structures of the male reproductive system
- two testes (produces sperm)
- vas deferens (sperm ride this guy to the urethra to be ejaculated)
- prostate gland (secretes fluid to nourish and protect sperm)
- penis
- urethra
male reproductive system
what hormone stimulates and maintains structure of the male reproductive system
testosterone
male reproductive system
describe testosterone
- responsible for many sexual and metabolic effects
- puberty and physical changes
- androgens help maintain changes caused by testosterone
- castration is removing the balls
male reproductive system
describe puberty
- puberty is the time when a childs body matures into and adults
- occurs between 9-14
male reproductive system
describe GnRH
- gonadotropin-releasing hormone
- causes the release of FSH and LH
- FSH and LH stimulate the production of sperm
male reproductive system
what is andropause
a period of less sexual activity and loss of testosterone effects
use it or lose it
