The Female

Reproductive System

what is the purpose of the female reproductive system
What is the purpose of the female reproductive system?

Purpose?

  • Making an egg
  • Getting sperm and egg together
  • Protecting and nurturing

the growing embryo

the female reproductive system
The Female Reproductive System

What are the parts of the reproductive system?

  • Uterus
  • Cervix
  • Fallopian Tubes
  • Ovaries
  • Vagina
slide4

Ovaries

What is the purpose of the ovaries?

  • Produces Hormones
  • Releases eggs
  • are the size of almonds
slide5

Fallopian Tubes

What is the purpose of the fallopian tubes?

  • Transports egg to the uterus
  • Where fertilization happens
slide7

Ovulation

ovary

egg

fallopian tube

slide9

Uterus

What is the purpose of the uterus?

  • Where the baby grows
  • Expands as the baby grows
  • Muscular tissue that pushes the baby out during labor
slide10

Uterus

Do you think all animals have a uterus?

slide11

Not all animals have a uterus.

Kangaroo babies grow

inside the mom's pouch.

Frogs leave their eggs

in water to develop.

slide12

Humans and other mammals keep

the developing baby inside

their bodies, in the uterus.

slide13

Cervix

What is the purpose of the cervix?

  • Opening to Uterus
  • Holds baby in Uterus
  • Opens to let baby out of Uterus
slide14

Vagina

What is the reproductive purpose of the vagina?

  • Where sperm is deposited
  • Birth Canal
slide15

Egg

  • Released by the ovaries
  • Travels down fallopian tube
  • Can’t swim ( no tail)
  • Fertilized in fallopian tube
  • Implants into uterus lining
  • Size of a pencil dot
slide17

The Male

Reproductive System

slide18

Testes

  • Contained in the Scrotum
  • Within each testis are clusters of hundreds of Seminiforous tubules
  • Which makesperm
  • produces testosterone
  • Need to be kept at a slightly lower temperature
slide19

Epididymis

  • Located on top of the testes
  • Sperm mature here
  • Sperm stored here 2-4 days
slide20

Vas Deferens

18 inch tube

carries sperm from

epididymis to urethra

slide21

Vas Deferens

There are two tubes, one on each side.

slide22

Glands

  • Seminal Vesicle, prostate & bulbourethral
  • Make seminal fluid which nourishes sperm & protects from acidic female reproductive tract
  • Sperm + seminal fluid= semen
  • 50-130 million sperm/mL
slide23

Penis

  • Used to deposit sperm into female
slide24

Sperm

  • Produced in the testes
  • Mature and stored in the epididymis
  • Travel through vas deferens to urethra
  • Ejaculated from urethra
  • Deposited in vagina
  • Swim through cervix and uterus
  • Swim into fallopian tubes to fertilize egg
slide25

Sperm

Which is human sperm?
