www.realityworks.com One Sperm + One egg = YOU! Experiential Learning Technology 2

www.realityworks.com Two Weeks • 2 weeks - Fertilization: the sperm and egg join in the fallopian tube to form a unique human being. • Forty-six chromosomes combine, which pre- determine all of a person's physical characteristics. • The MIRACLE BEGINS Experiential Learning Technology 3

www.realityworks.com Fetal Development Stages • Zygote Stage – Lasts 2 weeks – Sperm unites with ovum (egg) • Embryo Stage – Lasts 6 weeks – All major body systems begin to develop: • Central nervous system, brain, blood vessels, stomach, heart • Eyes, lungs arms legs, hands, feet • Fetus Stage – Lasts 7 months – Fetus grows and matures – Rapid growth of body, head, arms, legs – Organs develop for breathing, digestions, blood circulation – Nerves and muscles develop – Heart pumps blood through veins and arteries Illustration:Wikimedia.org/wikipedia/commons/3/35/Male_anatomy.png Experiential Learning Technology 4

www.realityworks.com 2 nd Month – Embryo (1 st Trimester) • Photo taken after surgery for an ectopic pregnancy – shows development of baby at only 6 weeks after conception • Major organs have begun to form • Hair follicles and nipples form, knees and elbows visible • Eyes have retina and lens • Major muscle system is developed End of 2 nd month (8 weeks) • begins the fetal stage of Photograph by University of development Minnesota Medical Photographer, Robert Wolfe. 1972 Experiential Learning Technology 5

www.realityworks.com Question: What does the embryo attach to so it can start to grow ? Experiential Learning Technology 6

www.realityworks.com Uterus • Pear-shaped, muscular-walled organ where the fetus develops for NINE months • Sit back and relax cause we are going to be here for a while! Experiential Learning Technology 7

www.realityworks.com 3 rd Month – Fetus (1 st Trimester) • Our nostrils, mouth, lips, teeth buds, and eyelids form • Our fingers and toes are almost complete • Our heartbeat can be heard with a stethoscope • All organs are present though immature • Red blood cells are produced in the liver Experiential Learning Technology 8

www.realityworks.com 4 th Month – Fetus (2 nd Trimester) • Our skin is slightly less transparent • Fine hair covers our entire body • We can suck our thumb, swallow, hiccup, grasp with our hands, kick, or even somersault! • Our facial features become clearer • Our brain is fully developed • Our bones are becoming harder • We can feel pain Experiential Learning Technology 9

www.realityworks.com 5 th Month – Fetus (2 nd Trimester) • Doctors can tell if we’re a boy or a girl • Hair, eyelashes, eyebrows appear • Teeth continue to develop • We have fingernails and fingerprints • Our organs are maturing • “Quickening” begins (mom feels us moving) Experiential Learning Technology 10

www.realityworks.com 6 th Month – Fetus (2 nd Trimester) • Our eyes open and close • The muscles in our arms and legs strengthen • Breath movement begins • We have hand and startle reflex • Footprints and fingerprints are forming Experiential Learning Technology 11

www.realityworks.com 7 th Month – Fetus (3 rd Trimester) • We are covered with downy hair called lanugo • Fat deposits begin to appear beneath wrinkly skin • Our nervous, circulatory, and other systems mature • A protective waxy substance (Vernix) covers our skin • Periods of activities are followed by periods of rest and quiet Experiential Learning Technology 12

www.realityworks.com 8 th Month – Fetus (3 rd Trimester) • We can hear sounds and may be startled by sudden noise • We can hear and recognize our mom’s voice • We usually moves into a head-down position Experiential Learning Technology 13

www.realityworks.com 9 th Month – Fetus (3 rd Trimester) • Increased fat our under skin makes us look less wrinkled • Our movement decreases with less room to move • We gain disease- fighting antibodies from our mom’s blood • We descends lower into pelvis—getting ready for birth Experiential Learning Technology 14

www.realityworks.com Question: What is connecting us to our mothers? Experiential Learning Technology 15

www.realityworks.com Umbilical Cord • Lifeline from mother to baby that carries food, oxygen, and water • This is what must be cut during delivery-when people say ‘cut the cord’ this is what they mean! Experiential Learning Technology 16

www.realityworks.com Question: What does the umbilical cord attach to so it can feed the growing embryo? Experiential Learning Technology 17

www.realityworks.com Placenta • Thick-walled circular organ, rich in blood supply connected to the umbilical cord • The placenta must also be delivered. This is called the AFTERBIRTH: – Tissues, fluids, and the placenta that passes our after the birth of the baby Experiential Learning Technology 18

www.realityworks.com What is the ‘bag of water’? • Amniotic Sac – Covering around the fetus – Also called the bag of waters – When this breaks the mother knows it’s almost time to deliver Experiential Learning Technology 19

www.realityworks.com You have to make a journey! • First the cervix must dilate to 10 cm • Cervix: – The neck of the uterus which has to stretch open during labor • Out through the vagina – Birth canal or female sex organ Experiential Learning Technology 20

www.realityworks.com Stages of Labor Experiential Learning Technology 21

www.realityworks.com You’re Here! Experiential Learning Technology 22

www.realityworks.com If things don’t go as planned: • Miscarriage: – Baby dies inside the mother’s uterus and is passed out early • Premature – Baby is born early • Breech Birth – Baby is born feet first • Caesarian Birth: – Baby is taken through the mother’s abdomen through surgery • Still Born: – Baby dies during labor and is born dead Experiential Learning Technology 23

www.realityworks.com Teen Pregnancy – Are teen mothers at higher or lower risks than adult women? – Why or why not? Experiential Learning Technology 24

www.realityworks.com Final Thought: If you are in contact with your birth mother, give her a HUGE hug and say THANK-YOU for bringing you into to world!! Experiential Learning Technology 25
