CHILD BIRTH MR. GARDNER SEXUALITY HEALTH

CHILD BIRTH Endometrium  Lining of the uterus Amniotic Sac  Bag of waters (shock absorber)  When it breaks, birth happens within 24 hours

CHILD BIRTH Placenta  Life support system (after birth)  Connected by an umbilical cord (about 18 inches) Genetics  XX = Female  XY = Male  XXY = ?? (1 gene will dominate, usually XX)

CHILD BIRTH Labor – 3 Stages  1. Dilation of cervix to 10 centimeters  2. Crowning Top of head enters vagina Delivery  3. Placenta (afterbirth)

Caesarean Section (C-Section) Cut through abdominal wall  1970’s = 4% of births  1990’s = 22%  2000’s = 33%

Reasons for a C-Section Breech  Baby is coming out feet first, side ways Umbilical cord Cervix doesn’t dilate Disease/injury Personal vanity

Multiple Births Twins – most common  Fraternal – different egg & sperm  Identical – same egg and sperm  Conjoined – same egg & sperm (doesn’t split)

Multiple Births Cont. Triplets3 Quadruplets4 Quintuplets5 Sextuplets6 Septuplets7 Octuplets8 Combined weight > 10 lbs, labor begins
