Hmmm. Chapter 1: Oh sugar honey iced-t, I missed my menstruation this month! Chapter 2: I tested positive for the Human Chorionic Gonadotropin Hormone (HCG)! Chapter 3: OMG, my breasts are tender and my nipples are really dark, EWW!!! Chapter 4: I cannot stop vomiting. What the heck is wrong with me?
Pregnancy & Early Development Chapter 18 (pp. 443-450) Objectives: SWBAT Describe how a human life begins Summarize how a baby develops during the three trimesters of pregnancy
#1 Fertilization (conception) When the egg and sperm unite in the fallopian tube. #2 Zygote A one celled fertilized egg.
United egg and sperm #3 Blastocyst Cell division The dividing mass of cells of the fertilized egg before implantation.
#4 Implantation The fertilized egg attaches itself to wall of the uterus. Pregnancy has occurred. Placenta, Umbilical Cord, Amniotic Sac and fluid are created.
What are the signs of pregnancy? Frequent urination
Sensitivity to smells Food aversions Nausea/vomiting/fatigue morning sickness Breast swelling and tenderness First missed period (if regular) Positive urine or blood test for human chorionic gonadotropin hormone (HCG)
Thumbs Up/Thumbs Down (true/false) The zygote attaches to the uterine lining. False Answer: blastocyst A woman is considered pregnant upon conception.
False Answer: implantation What the beginning stages look like inside of the body.. #5 Embryo
The developing baby for the first 8 weeks of pregnancy. In the seventh week, the embryo has both male and female primordial ducts x chromosome = female structures y chromosome = male organs
#6 Fetus The developing baby from the 9th week of pregnancy onward.
Check-in What is the difference between a fetus and embryo? Stages of Fetal Development!!! 6 volunteers needed.
Fetus Tri-fold Fold a blank piece of white paper into three parts. Fold them in any direction that makes you happy!!! Label each section 1, 2, and 3
Placenta An organ that will form during pregnancy to nourish the developing embryo and fetus. Nutrients, wastes, and gases are exchanged between the mothers blood and the babys blood. It comes out after birth.
Fetus Circulation Carbon Dioxide Wastes Hormones The blood of the mother and fetus
do not mix, but substance s are exchanged through the placenta by
Section # 1 Section # 1: Write down how the Placenta can be compared to a Refrigerator. Umbilical Cord A cord that connects the
developing baby to the placenta. Anything in the mothers blood can enter the babys blood through the Umbilical Cord, by way of the placenta.
Section # 2.. On your paper in half # 2, write down why the Umbilical Cord is the life line of the developing fetus. Amniotic Sac and Amniotic Fluid A sac filled with fluid
(Amniotic Fluid) which protects the baby during pregnancy. Section # 3 .. On your paper in section # 3, compare the Amniotic sac/fluid to a latex water balloon.
True or False Thumbs Up or Thumbs Down If a mother eats, injects, or inhales anything harmful, her baby can be affected.
True: Physical development during the 3 Trimesters of pregnancy... First Trimester (months 1-3) Fourth week: heart starts beating Arm and leg buds
appear Eyes and brain begin to develop Size of a BB pellet
Second Trimester (months 4-6 ) mother can feel The the fetus move or kick Reproductive organs
can be recognized as male or female Fetus can hear and recognize voices Hair forms on the body Head and facial features become apparent Fingers and toes grow
nails Third Trimester (months 7-9) Fetus gains most of its weight Brain develops further All other organs are almost complete
Fetus can grasp with his or her hands Fetus nervous system will continue to develop after birth True or False Thumbs Up or Thumbs Down
During the third to sixth month, the fetus begins to move and kick, a sign that its skeleton and muscles are developing. True: Day 2
Objectives: SWBAT Identify five things a couple can do to stay healthy before and during pregnancy Describe the stages of childbirth Describe the differences in three types of births Keeping Healthy Before and During
Pregnancy Prenatal care The healthcare provided for a woman during her pregnancy Her doctors visit should be supervised by an obstetrician (a doctor specialized in pregnancy and childbirth).
Identify 5 ways a woman can keep herself and her baby healthy... You may work with the person sitting next you. 1.Avoid alcohol and other drugs 2.Maintain proper nutrition 3.Take pre-natal vitamins 4.Get regular, moderate levels of exercise 5.Avoid environmental hazards
True or False Thumbs Up or Thumbs Down A pregnant woman doesnt need to visit the doctor until she begins to show, or look pregnant.
False: Regular doctor visits from before conception until birth of a baby are necessary to ensure health. Heredity and Disease Genetic Disorder Is caused by the inheritance of an abnormal gene or chromosome
Down syndrome, sickle cell, etc. Amniocentesis tests the amniotic fluid to detect certain genetic problems Diseases with a Genetic Link Breast cancer, colon cancer, high blood pressure, and diabetes True or False
Thumbs Up or Thumbs Down An amniocentesis test uses sound waves to draw pictures of a baby on a monitoring screen. This test can be used to determine if the baby is a boy or girl, how many babies there are, and whether the baby is growing in a
1. Labor (dilation) 2. Expulsion 3. Afterbirth Passage (placental) Number the stages of childbirth in the correct order. 1
2 3-1-2 3 Labor (Dilation) Begins with contractions, water breaks, and ends when
the cervix is fully dilated or effaced to 10 cm. The longest stage of childbirth. Epidural Anesthesia Anesthesia given to women in their back for pain
relief of labor and delivery. Woman does not feel pain, but she and the baby are not drugged. Expulsion Passage of the baby
through the birth canal. The baby is expelled. Ends when the Umbilical Cord is cut. Episiotomy An incision made in the skin below the vagina to
facilitate the passage of the baby through the vagina. Afterbirth Passage (Placental) A few minutes after the umbilical cord is cut, the mother delivers the placenta and the rest of the umbilical cord.
True or False Thumbs Up or Thumbs Down The stage of childbirth in which the baby is expelled from the vagina is afterbirth. False:
Expulsion True or False Thumbs Up or Thumbs Down If a pregnant woman wishes to not feel pain during childbirth, she can do an episiotomy.
False: Epidural Anesthesia True or False Thumbs Up or Thumbs Down
After birth the mother may breast-feed her baby immediately if the baby is not ill because breast milk provides all of the nutrients an infant needs and helps protect the baby from infections and stomach problems. True:
Vaginal Childbirth When the baby is born through the vagina or birth canal. Breech Birth When a baby comes out anyway other than head first, usually
feet first. Cesarean Section The surgical removal of the baby through the abdomen. http:// abcnews.go.com/Health/video/infant-womb-shown-holding-do
ctors-hand-18120525 What is the name of childbirth when the baby is born feet first? A. Natural or vaginal birth B. C-section C. Breech birth D. Alternative birth
Day 3 Objective: SWBAT Summarize four problems that can occur during pregnancy Differentiate between identical and fraternal twins List three changes that occur during early child
development Complete quiz Do Now Review Key Concepts Possible complications during pregnancy
Ectopic (tubal) Pregnancy When a fertilized egg implants anywhere but in the Uterus, usually in the Fallopian Tube. This is dangerous and
must be removed. Problems During Pregnancy Miscarriage (spontaneous abortion) Death of fetus from natural complications before the 20th week of pregnancy (vaginal bleeding) Rh incompatibility
A condition in which mothers immune system reacts against the fetuss blood due to an incompatibility in blood cell type. Problems During Pregnancy Fetal Alcohol Syndrome (FAS) A set of birth defects Toxemia (preeclampsia)
High blood pressure Gestational diabetes High blood sugar levels in mothers Premature birth Delivery before 38th week True or False Thumbs Up or Thumbs Down
High blood pressure during pregnancy is called preeclampsia. False: True
Abortion When a pregnancy is terminated on purpose. And then there were 2, no wait, 3, OMG, 4.. Multiple Births
Identical Twins Fraternal Twins Triplets ETC.
Identical Twins Fertilized egg splits They will share one placenta They will always be the same sex and are identical. Fraternal Twins
Two separate eggs are fertilized by two separate sperm. They will have their own placenta. They are not Identical. 2. When two eggs are released and fertilized by the two
separate sperm of the same father, what might happen? A. Identical twins B. Triplets C. Fraternal twins D. Heteropaternal Superfecundation True or False
Thumbs Up or Thumbs Down The fastest period of growth after birth takes place from birth to the age of one. True: STRANGE BUT TRUE
Identical Triplets Life of Triplets STRANGE BUT TRUE Mixed-Race Twins STRANGE BUT TRUE Heteropaternal Superfecundation Twins with different fathers (bipaternal)
Two eggs are ovulated during the same cycle and fertilized at different points within the five-day fertility window, resulting in a bouncing pair of twins Media Buzz Kate raises 8 children
