  9. A new beginning • Once upon a time….. • Single sperm joins the ovum or egg and the genes carried by the ovum and sperm combine to for new life

  10. Terms • Pregnancy - the time when a fertilized egg grows and develops into a baby in the women’s uterus. • Embryo – from the time the sperm and ovum join until the end of the eighth week • Fetus – from the eighth week until birth

  11. Changes in the Mother’s Body • Hormone is released indicating to the body that the mother is pregnant. • During a pregnancy test, this hormone will show up in higher levels • Often times this increase hormone may cause morning sickness, increased breast size to prepare for breast milk for the baby • The women’s uterus stretches to accommodate the baby. • A woman may also experience swelling of the hands and legs and feet, difficulty sleeping, food cravings, and other changes….

  12. Nourishing the fetus • Almost everything that goes into the mother’s body enters her bloodstream and goes into the placenta. • Placenta – an organ that grows in the woman’s uterus during pregnancy and allows nutrients, gases and wastes to be exchanged between the mother and the fetus.

  13. Nourishing the Fetus • The fetus gets its only nutrients from the food its mother eats. • The mother needs to eat healthy to ensure the health of the baby • The mother will also need to take special vitamins to ensure proper health • A mother can harm her baby by taking drugs, drinking alcohol or smoking. • Regular check ups are a must

  14. The First Trimester • This is the first three months of a pregnancy • Once the ovum is fertilized, an explosion of cell growth occurs • By the 2nd week, the fertilized egg implants in the uterus and is called an embryo • By the 3rd week, most major organs have started to form • By the 5th week, facial features take shape • By the 8th week, brain waves are detected • By weeks 9 and 11, arms legs hands and internal organs form

  15. Second trimester • This is the fourth through the sixth month or weeks 13-27 • At the start the fetus is almost 3 inches long, by the end the fetus will be three times that length • By 16 weeks the mother may feel movement • By 18 weeks the fetus reacts to sound • By 24 weeks eyelashes and eyebrows are well-formed

  16. Third Trimester • The last 3 months or 12 weeks, of pregnancy • At the start the fetus is about 10 inches long and weighs about 2 pounds • More muscle development and movement • By week 28 fetus eyes open • By week 29 layers of fat form beneath the skin and the fetus can “practice” breathing • By week 33 most organs are functioning fully • By week 35 the fetus responds to light and • By week 38 the fetus is born…. THE END Here you are

  17. Birth • The passage of the baby from its mother’s uterus to outside • Labor – process that lasts from the time contractions begin until the delivery of the child and the placenta • Labor is different for every mother and every birth • The umbilical cord is cut • Healthy babies cry and breathe almost immediately • The placenta is delivered lastly

  18. Some possible complications of pregnancy and birth • Miscarriage – the loss of the pregnancy • Ectopic pregnancy – embryo implants outside the uterus • Preclampsia – medical problem during a woman’s pregnancy • Gestational diabetes – high blood sugar that needs treatment • Rh incompatibility – condition in which the fetus and mother’s blood are not compatible • Premature birth – birth of a baby before the 37th week • Breech birth – baby is born upside down with the bottom coming out first, most babies are delivered C-secition • Oxygen deprivation – lack of oxygen to a baby’s brain during birth • Still birth – delivery of an infact that is dead after 20 weeks or more of pregnancy
