Slide 14 of 28 Section 19.3 Childbirth The Postpartum Period During the first six weeks, called the postpartum period, many changes take place.
The newborns lungs begin to function for the first time. The circulatory system and heart undergo changes. The nervous system reacts to new sensations. For the mother, changing hormone levels signal the breasts to produce milk and cause the uterus to gradually shrink back to its normal size. Hormonal changes and fatigue may cause the mother to feel overwhelmed. Slide 15 of 28 Section 19.3 Childbirth
Complications at Birth Some complications result in a surgical delivery or premature birth. Low birthweight and the birth of more than one baby also may cause complications. A stillbirth occurs when a fetus dies and is expelled from the body after the twentieth week of pregnancy. Slide 16 of 28 Section 19.3 Childbirth
Surgical Delivery Sometimes delivery through the cervix and vagina is not possible because of the position of the fetus in the uterus the narrowness of the mothers hips illness other conditions A cesarean section (suh ZEHR ee un) is a surgical method of birth. First the doctor makes an incision in the lower abdomen into the uterus, then he or she removes the baby and placenta.
Slide 17 of 28 Section 19.3 Childbirth Premature Birth Delivery of a live baby before the 37th week of pregnancy is called premature birth. The lungs of a premature baby are usually not fully developed. The baby may have additional problems if other organs arent fully developed. A premature baby may receive care in an incubator.
Slide 18 of 28 Section 19.3 Childbirth Low Birthweight A newborn that weighs less than 5.5 pounds at birth is considered to have low birthweight. Premature and low-birthweight babies face an increased risk of health problems as newborns, chronic lifelong health problems, and even death.
Slide 19 of 28 Section 19.3 Childbirth Multiple Births The delivery of more than one babyfor example, twins, triplets, or quadrupletsis called a multiple birth. These births carry greater risk to the mother and babies, and are closely monitored by doctors. Slide 20 of 28
Section 19.3 Childbirth Identical Twins Twins that develop from a single fertilized egg, or zygote, are called identical twins. Because they develop from identical embryos, identical twins have the same inherited traits and are the same sex. Slide 21 of 28
Section 19.3 Childbirth Identical Twins A sperm fertilizes a single egg. Identical twins result. Early in development, the embryo splits and forms two identical embryos.
Slide 22 of 28 Section 19.3 Childbirth Fraternal Twins Sometimes two eggs are released from the ovary and are fertilized by two sperm. Fraternal twins are no more alike than any other siblings, and they may or may not be the same sex. Slide 23 of 28
Section 19.3 Childbirth Fraternal Twins Two different sperm fertilize two eggs. Fraternal twins result. Each of the fertilized eggs develops into an embryo. Slide 24 of 28
Section 19.3 Childbirth Triplets or More Triplets, quadruplets, and other multiple births are less common than twins. Slide 25 of 28 Section 19.3 Childbirth Vocabulary
