Review lesson
Reproduction
Slide 1 - Tekstslide
Male reproductive system
sperm duct: transports sperm from the epididymis to the urethra
seminal vesicle gland: produces liquid that forms semen together with the sperm cells
prostate: produces liquid that forms semen together with the sperm cells
epididymis: stores sperm cells until they are needed
testicle: produces the sperm cells and the hormone testosterone
Slide 2 - Tekstslide
Male reproductive system
6. scrotum: keeps the testicles outside the body at a lower body temperature. (1 or 2 degrees) better for sperm production and survival 7. penis: this is meant for sex, it has this shape to be able to deliver the sperm cells as far into the female body as possible. 8. bladder: stores urine that has come from the kidneys 9. urethra: moves urine and semen out of the body 10. glans: the sensitive part of the penis 11. foreskin: this covers and protects the glans
Slide 3 - Tekstslide
Female reproductive system
1. oviduct (fallopian tube): transports the ova to the uterus
2. ovary: produces the ova (eggs) and the hormones estrogen and progesterone
3a. uterus: is like a large sack that holds the developing baby
3b. uterus wall: thick wall on the outside of the uterus made of muscles
3c. cervix: the entrance to the uterus from the vagina
4. vagina: the opening of the woman's body where the penis fits in.
5. hymen: the half-open covering to the entrance of the vagina.
6. bladder: store urine that comes from the kidneys
Slide 4 - Tekstslide
Female reproductive system
7. urethra: the tube that move urine out of the body
8. clitoris: the sensitive part of the female reproductive system, this works the same as the glans with men.
9. inner labia: produces mucus to protect the reproductive organs and also lubricates the area during sex.
10. outer labia: this helps protect the reproductive organs.
Slide 5 - Tekstslide
Sexual development
Primary sexual characteristics: characteristics that you are born with
Secondary sexual characteristics: develop later in life, usually during puberty
Caused by the production of hormones
Slide 6 - Tekstslide
What are hormones?
These are chemicals that slowly change things in our bodies
They are transported through our blood
Slide 7 - Tekstslide
Male secondary sexual characteristics
Hormone = testosterone
Growth of hair
Growth of penis and testicles
Enlargment of Adam's apple
deepeing of the voice
Increased muscles and strength
Increased secretions of oil and sweat -> acne & body odor
Slide 8 - Tekstslide
Female secondary sexual characteristics
Hormone = Estrogen & Progesterone
Breasts and nipples grow bigger
Body hair
Widening of the hips
More fat deposists (thighs, hips and buttocks)
Ovulation and menstruation start
Increased secretions oil and sweat -> odor and acne
Slide 9 - Tekstslide
What is menstruation?
Release of blood from the uterus through the vagina
Start around age 12
Slide 10 - Tekstslide
How does it happen?
Hormones estrogen en progesterone build up uterus lining
Fertilized egg could attach to this
No fertilized egg? --> Lining is shed
cylce: it happens over and over again (450 times in a life time)
Slide 11 - Tekstslide
4 Phases
Phase 1 (day 1-5) : menstruation
Uterus lining is shed through the vagina (no fertilized egg)
Phase 2 (day 6-12): repair phase
uterus lining build new layer of mucus
new egg cell develops in the ovary
Slide 12 - Tekstslide
4 Phases
Phase 3: Ovulation (day 13-15)
A new ova is released and send down the oviduct
Phase 4: Receptive phase (day 16 - 28)
Uterus lining grows to form a 'nest' for the egg cell
No fertilized egg cell? --> cycle starts again!
Slide 13 - Tekstslide
Fertilisation
Gametes are sex cells
sperm and egg (ova)
contain half the DNA of regular body cells
Fertilisation = melting together of sperm and egg cell
Zygote = 'baby cell' sperm and egg cell melted together
Embryo = when cells starts to multiply
Slide 14 - Tekstslide
Slide 15 - Tekstslide
How do cells multiply?
Body cells
'clones'
Sex cells
sperm and egg 'different'
Slide 16 - Tekstslide
Pregnancy
Placenta
spongy mass of blood vessels
transport oxygen, nutrients & carbon dioxide
Amniotic sac
membrane around the fetus filled with water
protects the fetus
Umbilical cord
connection placenta to fetus
Slide 17 - Tekstslide
Childbirth
-Amniotic sac breaks
-after 9 months / 40 weeks
Muscles of the uterus contract
Dilation contractions - open up the cervix
Pushing contractions - uterus pushes the baby out
after 15 min. -> afterbirth (placenta + amniotic sac)
Slide 18 - Tekstslide
Contraceptives
Chemical method
Natural method
Sterilization
Intrauterine methods
Emergency contraception
Barrier method
Slide 19 - Tekstslide
Chemical methods
Spermicides (zaaddodend middel)
Pill (de pil)
Patch (hormoonpleister)
Injection (hormooninjectie)
Rods (hormoon implantaat)
Ring (NuvaRing)
Slide 20 - Tekstslide
Natural methods

Rhythm (periodiek onthouding)
Slide 21 - Tekstslide
Sterilisation
Tubal ligation (females)
Vasectomy (males)
Slide 22 - Tekstslide
Intrauterine method
IUD (intra uterine device): copper or hormones
spiraaltje
Slide 23 - Tekstslide
Emergency contraception
Plan B ( morning after pill)
Abortion pill
Slide 24 - Tekstslide
