3 Fallopian TubePair of tubes connecting the egg from the ovary to the uterus.
4 OvulationOnce a month a woman’s egg is released from the ovaries
5 HormonesChemicals in the body that cause changes
6 UterusOrgan in a woman’s body where a baby develops during pregnancy.
7 TERMS Sperm Testicle- male organ where sperm are produced male cell needed for reproductionTesticle- male organ where sperm are producedVas Deferenes – tube that connects the Testicles to the UrethraUrethra – tube that allows urine and semen to be releasedEjaculation – the release of semenSemen – a mixture of sperm and other bodily fluids
8 TERMSConception (fertilization)-the union of an ovum and sperm, resulting in the beginning of a pregnancy
9 What happens during conception? #1 Sperm swim through the cervix, through the uterus, into the Fallopian tubes.
10 What happens during conception? #2 If Egg present, sperm crowd around it and try to break through the surface.
11 What happens during conception? Only one sperm is successful.
12 What happens during conception? Fertilization ONLY OCCURS IN THE FALLOPIAN TUBES
13 What happens during conception? Once inside sperm seals out remaining sperm, which eventually die.
14 What happens during conception? Fertilized egg, travels down the fallopian tube into uterus and attaches to the wall of the uterus/IMPLANTATION!
16 ImplantationProcess of attachment of the embryo to the maternal uterine wall.
17 BlastocystA hollow ball of cells from the fertilized egg that implants itself into the uterus lining
18 Amniotic Sac“Bag” surrounding baby in uterus that holds amniotic fluid
19 Amniotic FluidLiquid that surrounds and protects the developing baby in the uterus during pregnancy“My water broke.” is a term women use.It’s your amniotic sac that broke and the amniotic fluid comes out.
20 Umbilical CordLong tube that connects the placenta to the developing baby during pregnancy; carries food and oxygen to the baby
21 Placenta Tissue in the uterus of a pregnant woman rich in blood vesselstransports food and oxygen from mom to babyTransports waste from baby to mom
22 Full TermChild carried the entire nine months of pregnancy.
23 Prenatal Terms Quickening Lightening 4-5th month When mother feels that baby moveLighteningBaby drops into pelvic area before birth
24 Order of DevelopmentA baby’s development is grouped into three stages:ZygoteEmbryoFetus.

64 Partner up!You will be put into groups to complete the next assignments.
65 “Name That Month” Directions: Class will be arranged into nine groups. Each group will receive one case study strip.Each group will read the case study (table tent) together to decide which month of the pregnancy is described.Be ready to share your response.
66 Case Study #1The zygote is the size of a pin head. The egg is attached to the lining of the uterus. The zygote is attached to the lining of the uterus and becomes an embryo. The mother has missed her menstrual cycle, her breasts have enlarged, and she has to urinate frequently.What month is this?Month 1
67 Case Study #2The fetus is inches long and weighs 5-6 pounds. The fetus continues gaining weight until the week before birth. The skin becomes smooth as fat deposits continue to develop. Movement decreases as the fetus has less room to move around. The fetus acquires antibodies to fight disease from the mother’s blood and moves into the pelvis, ready for birth. The mother feels lightening as the fetus drops into the pelvis; breathing becomes easier. Other discomforts continue, and a total weight gain of pounds is typical. False labor pains called Braxton Hicks contractions may be experienced.What month is this?Month 9
68 Case Study #3The embryo is ¼ inch long and has developed face, eyes, ears, and limbs. The bones have begun to form. The embryo changes to a fetus and remains a fetus until birth. The mother has swelling of breasts and increased urination due to pressure on the bladder. She is not having nausea or morning sickness.What month is this?Month 2
69 Case Study #4The fetus is 3 inches long and weighs one ounce. The fetus can suck its thumb, swallow, hiccup, and move around. The facial features become clearer. The mother’s abdomen continues to grow slowly. Most discomforts of early pregnancy, such as morning sickness, usually are gone. Appetite increases.What month is it?Month 4
70 Case Study #5The fetus is about 8-10 inches long and weighs about 8-12 ounces. The mother senses fetal movement as strong kicks, thumps, and bumps---some may be visible. The mother gains as much as pounds during this month.What month is it?Month 6
71 Case Study #6The fetus is about inches long, weighs about 2 ½-3 pounds as the month begins. The weight gain continues rapidly. The fetus may react to loud noises with a reflex jerking action. The fetus moves into a head-down position. The mother may show signs of discomfort from increased size. She might show signs of backache and fatigue along with leg cramps and shortness of breath. The fetal kicks may disturb the mother’s rest. At the beginning of the month, weight gain totals about pounds.What month is this?Month 8
72 Case Study #7The fetus is about one inch long. Nostrils, mouth, lips, teeth buds and eyelids form. Fingers and toes also develop. All the organs are present, although they are immature. The mother’s breasts become firm and full, and they may ache. Nausea, fatigue and frequent urination are still present. The abdomen becomes slightly larger. The uterus is about the size of an orange. The mother has gained 2-4 pounds.What month is this?Month 3
73 Case Study #8The size of the fetus is inches long and weighs about 1½ -2 pounds as the month begins. The fetus experiences periods of rest and quiet. The mother’s increased size may affect her posture.What month is this?Month 7
74 Case Study #9The fetus is about 6 ½-7 inches long and weighs about 4-5 ounces. Hair, eyelashes, and eyebrows appear and teeth continue to develop. The organs are maturing and the fetus is becoming more active. The mother’s abdomen has become large enough to let others know she is pregnant. Slight fetal movements are felt. Increased size has begun to affect her posture.What month is this? Month 5
75 Fetal Development Growth Chart Materials:Construction paperRulerScaleColored PencilsPowerPoint NotesDirections:Use materials to create a size chart of the growth of the fetus each monthYou should chart it on paper, month by month and beside each month measure the size.Look for teachers example.
76 Fun Way to Remember Directions: Materials: Use teacher’s example to create a fun way to remember the 9 months of pregnancy for Baby and Mother.Materials:Index cardsColored pencilsTeachers MnemonicI will post on document camera
77 3.02 Fetal Development Test Review Directions:Complete MiTiReLa 3.02 Learning Mode.Record score after clicking daily progress.Teacher will need to see and sign off on your MiTiReLa paper.
78 Let’s see what you know! Directions: Close eyes and put heads down on desks.I will describe each month of pregnancy.You will hold up the # of fingers corresponding to the month of pregnancy that is described.Teacher will rotate around the room and touch student’s hand if incorrect.If hand is touched you will know you need to try again!If hand is not touched, leaved your fingers up until the next description is called out.Test may consists of 9-18 questions.
89 Guided practiceYou will pick a number 1-9 out of the cup. That # will represent a month of pregnancy.After you have chosen a month, you will find an object in the classroom that would represent the size of the embryo and fetus at each stage of development.After objects are collected, display and give a description of the growth represented by each object.
90 Independent PracticeYou will be grouped with a partner to decorate a bulletin board according to the month of pregnancy you choose.Bulletin Boards must be neat, attractive, easy to read-- words must be big enough to read, no grammatical errorsYour bulletin board must provide the following:Pictures pointsGrammatical Errors pointsLabels pointsContent (info discussed in class) 40 pointsGather info from notes, textbook, InternetCreative pointsTOTAL Points
