How it all started • Pregnancy is the time period from conception to birth. Pregnancy occurs when fertilization or conception happens. That is the process of a sperm cell connecting to an egg cell. During this the persons hormones change. Also, menstruation, enlarged breasts, frequent urination, fatigue, and morning sickness occur.
How it all started 2 • After fertilization, the new cell is called the placenta. The placenta is an organ that attaches its self to the inner wall of the uterus. The umbilical chord attaches to the placenta and the developing baby’s belly button. The umbilical chord is a ropelike structure through which the baby and the mother exchange oxygen, nutrients, and waste.
Baby Develpment • When the baby grows it is surrounded by a thin protection bubble called the amniotic sac • The amniotic sac fills up with amniotic fluid that helps the baby stay stabilized and controls temperature
First Trimester • First Month • The babies heart, brain, nerves, and lungs form • Baby is referred to as an embryo • Eyes and ears can be seen and digestive system forms • Embryo is about 1/3 of an inch • Second Month • Arms, fingers, legs, and toes form • The heart becomes four chambers • Head forms and facial characteristics appear. • Baby now referred to as a fetus
First Trimester (cont) • Third Month • First external sign of sex appear • Fetus movement occurs • Weighs about 1.5 lbs and 1.5 inches long
Second Trimester At the end of the fourth month: • Fetus begins to develop skin • Begins to stat kicking and moving it’s arms • Weighs between 6 to 7 ounces and is 4 to 5 inches long
Second Trimester Fifth Month Sixth month Fetus responds to noise and movement Gains heartbeat Baby moves a lot Weighs about 1.5 pounds and about a foot long • Develops hair • Fetus grows fingernails and eyelashes • Rate of growth slows down • Fetus now weighs about a pound • About 9 to 10 inches long
Third Trimester • In the 7th month the babies eyes open, arms and legs move, and is about 3 pounds • In the 8th month almost all the organs are complete, weighs about 4 pounds and about 18 inches • In the 9th month the skin is smooth and polished, eyes turn to a slate color, and is weighed in at about 6-9 pounds and 19-21 inches
Prenatal Care Tips • Prenatal care is the care that is given to the mother-to-be and the baby • A person that specializes in this is called an obstetrician • Choosing good behaviors will promote a healthy pregnancy • Avoid smoking during pregnancy because nicotine makes the mother lose her appetite
Prenatal Care Tips 2 • Fetal Alcohol Syndrome • The presence of severe birth defects in babies with mothers who drink alcohol while pregnant.
Prenatal Care Tips 3 • An obstetrician will examine the pregnant female to figure out how healthy she is • The doctor will discuss healthful behaviors and the responsibilities she will take on
Kinds of Births • Breech Birth-baby comes out butt first • Cesarean Birth-baby pulled out of female through incision and the “bikini line” • Premature Birth-birth of a baby before it is fully developed
Labor and Delivery • Labor is a three step process which results in birth of a baby • Fake contractions are called Braxton hicks
Stage One • The first stage of labor is called effacement and dilation. Effacement is the thinning and shortening of the cervix. • Contractions of the uterus cause the cervical opening to dilate and stretch • This allows the baby’s head to enter the vagina, also known as the birth canal • This can last from an hour to fifteen hours
Stage Two • The second stage of labor is the delivery of the baby • The baby comes out the uterus and into the birth canal. Then the mother has to do contractions to push the baby out. • When the head is seen, the baby will very soon be delivered • This stage lasts about half an hour to 2 hours
Stage Three • The third stage of labor is the delivery of the placenta • The “afterbirth” is the placenta and other membranes that support the newborn • This stage lasts about 10 to 30 minutes
Important Term • Apgar Scale- a scoring system to rate the health of a newborn baby
