Reproductive System Diana Martinez P4
major functions of reproductive system
to produce sperm and egg cells
Males
sperm is produced in the testes & stored in the epididymis to mature
Females
egg are produced in the ovaries & transported to Fallopian tubes to get fertilized
transport and sustain sperm and egg cells
sperm cells are ejaculated from the epididymis through the vas deferens, then ejaculatory tract then urethra.
eggs are transported from ovaries to fallopian tubes where they can be fertilized
nurture developing offspring
produce hormones
testosterone
progesterone
estrogen
FSH
LH
anatomy of male reproductive structure & function
testes
produces sperm cells
epididymis
complete maturation process then stored on lower part of epididymis
scrotum
regulates temperature of sperm in testes; surrounds testes; posterior to penis; skin & subcutaneous tissue
vas deferens
carries sperm from epididymis to the urethra
urethra
passageway for semen and urine
penis
transfers sperm to vagina
accessory glands (secrete fluids into urethra)
prostate gland
encircles the urethra; function: enhance motility of sperm
seminal vesicle
has short ducts that join into ductus deferen to form ejaculatory duct which empties to urethra; provides energy for sperm
bulbourethral/cowpers gland
secretes fluid that neutralizes the acidity of the urine residue in the urethra, helps to neutralize the acidity of the vagina, and provides some lubrication for the tip of the penis during intercourse
anatomy of female reproductive structure & function
ovaries
2 solid ovoid structures on each side of the uterus; sex cells develop in ovaries;
fallopian tubes
2 uterine tubes; attached to ovaries through frimbriae
uterus
muscular organ that receives the fertilized oocyte; provides an appropriate environment for the developing fetus
vagina
passageway for menstrual flow, receives the erect penis during intercourse, and is the birth canal during childbirth
accessory glands
external genitalia
clitoris
labia minora
labia majora
anus
mons pubis
prepuce
urethral orifice
mammary glands
produce milk; they are modified sweat glands
oogenesis=spermatogenisis
male hormones
follicle stimulating hormone (FSH)
stimulates spermatogenesis
luteinizing hormone (LH)
stimulates production of testosterone
testosterone
stimulates the development of male secondary sex characteristics and spermatogenesis
female hormones
FSH
LH
progesterone
estrogen
