Ovaries - these contain developing eggs or biggercellsdilatesdrugsembryoFertilisationfertilisedfluidsgreasehairhormoneslubricationmenstrualmilkmusclenucleusnutrientsovaovaryplacentapushtenderumbilicalurinate. One ova is produced every month.
Womb - this is a muscular organ where the biggercellsdilatesdrugsembryoFertilisationfertilisedfluidsgreasehairhormoneslubricationmenstrualmilkmusclenucleusnutrientsovaovaryplacentapushtenderumbilicalurinate ovum develops into a baby. Part of the lining is shed each month in the biggercellsdilatesdrugsembryoFertilisationfertilisedfluidsgreasehairhormoneslubricationmenstrualmilkmusclenucleusnutrientsovaovaryplacentapushtenderumbilicalurinate cycle.
Cervix - this is a ring of biggercellsdilatesdrugsembryoFertilisationfertilisedfluidsgreasehairhormoneslubricationmenstrualmilkmusclenucleusnutrientsovaovaryplacentapushtenderumbilicalurinate at the lower end of the womb. It allows sperm, menstrual blood and the baby to pass through. During childbirth it biggercellsdilatesdrugsembryoFertilisationfertilisedfluidsgreasehairhormoneslubricationmenstrualmilkmusclenucleusnutrientsovaovaryplacentapushtenderumbilicalurinate (widens).
Fallopian tubes - these funnel-ended tubes take the egg when it has been released from the biggercellsdilatesdrugsembryoFertilisationfertilisedfluidsgreasehairhormoneslubricationmenstrualmilkmusclenucleusnutrientsovaovaryplacentapushtenderumbilicalurinate.
Vagina - this passage leads up to the womb. It's lining secretes mucus for biggercellsdilatesdrugsembryoFertilisationfertilisedfluidsgreasehairhormoneslubricationmenstrualmilkmusclenucleusnutrientsovaovaryplacentapushtenderumbilicalurinate. The outer walls separate to widen the passage in childbirth.

Fertilisation
1. ovulation
2. the ovum moves along the Fallopian tube
3. biggercellsdilatesdrugsembryoFertilisationfertilisedfluidsgreasehairhormoneslubricationmenstrualmilkmusclenucleusnutrientsovaovaryplacentapushtenderumbilicalurinate - a sprem reaches the egg. It's biggercellsdilatesdrugsembryoFertilisationfertilisedfluidsgreasehairhormoneslubricationmenstrualmilkmusclenucleusnutrientsovaovaryplacentapushtenderumbilicalurinate fuses with the egg nucleus.
4. The embryo (first 8 weeks) starts as a ball of biggercellsdilatesdrugsembryoFertilisationfertilisedfluidsgreasehairhormoneslubricationmenstrualmilkmusclenucleusnutrientsovaovaryplacentapushtenderumbilicalurinate which keeps dividing.
5. Implantation (after 10 days) - the biggercellsdilatesdrugsembryoFertilisationfertilisedfluidsgreasehairhormoneslubricationmenstrualmilkmusclenucleusnutrientsovaovaryplacentapushtenderumbilicalurinate is embedded in the lining of the womb.

First timester (0-3 months)
The foetus' toes and fingers may be joined by webs of skin. Fingernails grow. It is recognisable as a human being. The mother's breasts become biggercellsdilatesdrugsembryoFertilisationfertilisedfluidsgreasehairhormoneslubricationmenstrualmilkmusclenucleusnutrientsovaovaryplacentapushtenderumbilicalurinate and larger. Morning sickness may occur. The mother starts to gain weight.

Second trimester (3-6 months)
The foetus grows quickly and moves more. Fine biggercellsdilatesdrugsembryoFertilisationfertilisedfluidsgreasehairhormoneslubricationmenstrualmilkmusclenucleusnutrientsovaovaryplacentapushtenderumbilicalurinate covers its body. External genital organs can be seen. The mother's heart rate increases and the uterus gets biggercellsdilatesdrugsembryoFertilisationfertilisedfluidsgreasehairhormoneslubricationmenstrualmilkmusclenucleusnutrientsovaovaryplacentapushtenderumbilicalurinate. From about 20 weeks the mother can feel the baby move.

Third trimester (6-9 months)
The foetus is more mature. The body is covered in a thick biggercellsdilatesdrugsembryoFertilisationfertilisedfluidsgreasehairhormoneslubricationmenstrualmilkmusclenucleusnutrientsovaovaryplacentapushtenderumbilicalurinate which stops the skin from getting waterlogged. After about week 28 it would just be able to survive if born prematurely. The mother's skin stretches over her abdomen. She might feel slight contraction of the uterus as birth approaches. The uterus might press on the bladder, making the mother need to biggercellsdilatesdrugsembryoFertilisationfertilisedfluidsgreasehairhormoneslubricationmenstrualmilkmusclenucleusnutrientsovaovaryplacentapushtenderumbilicalurinate more frequently.

In the early stages the embryo gets the nutrients and oxygen from the biggercellsdilatesdrugsembryoFertilisationfertilisedfluidsgreasehairhormoneslubricationmenstrualmilkmusclenucleusnutrientsovaovaryplacentapushtenderumbilicalurinate in the uterus. Later on it is joined to the mother by the biggercellsdilatesdrugsembryoFertilisationfertilisedfluidsgreasehairhormoneslubricationmenstrualmilkmusclenucleusnutrientsovaovaryplacentapushtenderumbilicalurinate cord and placenta. In the placenta, oxygen and biggercellsdilatesdrugsembryoFertilisationfertilisedfluidsgreasehairhormoneslubricationmenstrualmilkmusclenucleusnutrientsovaovaryplacentapushtenderumbilicalurinate are exchanged between the mother's blood and that of the baby. The placenta also produces female biggercellsdilatesdrugsembryoFertilisationfertilisedfluidsgreasehairhormoneslubricationmenstrualmilkmusclenucleusnutrientsovaovaryplacentapushtenderumbilicalurinate which stop more ova from developing and ensure that the uterus develops at the same rate as the baby. The hormones also make sure that the breasts are ready to produce biggercellsdilatesdrugsembryoFertilisationfertilisedfluidsgreasehairhormoneslubricationmenstrualmilkmusclenucleusnutrientsovaovaryplacentapushtenderumbilicalurinate after the baby is born.

Birth
After about 40 weeks the baby is ready to be born.
Contractions of the uterus force the baby's head down to the cervix. The cervix biggercellsdilatesdrugsembryoFertilisationfertilisedfluidsgreasehairhormoneslubricationmenstrualmilkmusclenucleusnutrientsovaovaryplacentapushtenderumbilicalurinate and the mucus plug is discharged. Amniotic fluid might escape - the waters break.
As contractions get stronger the mother feels a strong urge to biggercellsdilatesdrugsembryoFertilisationfertilisedfluidsgreasehairhormoneslubricationmenstrualmilkmusclenucleusnutrientsovaovaryplacentapushtenderumbilicalurinate until the baby is born.
Further contractions push the biggercellsdilatesdrugsembryoFertilisationfertilisedfluidsgreasehairhormoneslubricationmenstrualmilkmusclenucleusnutrientsovaovaryplacentapushtenderumbilicalurinate and umbilical cord out of the mother's body.
Some mothers have little pain in childbirth, others control it with natural methods or biggercellsdilatesdrugsembryoFertilisationfertilisedfluidsgreasehairhormoneslubricationmenstrualmilkmusclenucleusnutrientsovaovaryplacentapushtenderumbilicalurinate.
