Pregnancy, Childbirth Flashcards
Only a few hundred sperm that enter the vagina reach the egg, and only one can fertilize it. Within seconds of fertilization, the surface of the egg changes so that no more sperm can enter the egg
Fertilization
The United egg and sperm is called a zygote . Within 36 hours, while the zygote is traveling through the Fallopian tube begins to divide
The zygote
The original cell divided to make 2 cells. From this stage until about 9 weeks, the growing structure is called an embryo. The two-called embryo divides into 4 cells and so on.
Cell division
About 5 days after fertilization, the embryo reaches the uterus, where it floats free for a few days. By this time’ it is made up of about 59 to 100 cells. The structure is no longer a solid mass of cells, but sheer of cells surrounding a hollow center
The Blastocyst
Once the blastocyst forms, it begins to attach itself to wall of the uterus
Implantation
Fluid-filled bag of this tissue that develops around the embryo. The embryo floats in amniotic fluid
Amniotic soc
Attachment holding the embryo to the wall of the uterus. Oxygen and nutrients are passed from the mothers blood to the embryo through the placenta
Placenta
“Embryos lifeline” after 25 days of fertilization*carries nutrients and oxygen through the blood vessels
Umbilical cord
How many more calories does the women have to consume
300 more calories
Why avoid alcohol, other drugs
Can bring harm or damage to the baby, decreas ether chance to life, or life problems
6 important nutrients
Folic acid Protein Calcium Iron Vitamin A Vitamin B complex
Folic acid
Formation of neural tube, brain, and spinal cord development
Protein
Muscle formation and growth
Calcium
Bone and tooth formation, nerve and muscle development
Iron
Oxygen delivery by blood cells
Vitamin A
Call and bone growth, eye development
Vitamin B
Nervous system development
The blastocyst implants in the Fallopian tube or elsewhere in the abdomen instead of the uterus
Ectopic pregnancy
Death of an embryo or fetus within the 20 weeks of pregnancy
Miscarriage
(Toxemia) high blood pressure swelling of the wrists and ankles, and high level of protein in the urine
Preeclampsia
Work preformed by mothers body to push the fetus out(2-24hrs)
Labor
Contractions of the uterus continue and the baby is pushed out(30min-24hrs)
Delivery of the baby
Contractions of the uterus push out the placenta, also called the afterbirth(15-30min)
Delivery of afterbirth
A cesarean section (c-section) in which the doctor makes an incision in the lower abdomen into the uterus. Then the doctor removes the baby and placenta
Surgical delivery
Delivery of a baby before the 37th week of pregnancy, before fully developed
Premature birth
A baby that weighs less than 5.5 pounds. Baby is not fully developed
Low birthweight
Emotions during the Postpartum period
Hormonal change and fatigue
18 months
Nurse, cry, direct gaze upon you, not smile until 1 month, organs and systems not fully developed, and bones are still flexible
18months-3years
Talking, loose ‘baby like’ appearances, appetite decreases as growth slows, and coordination
3-6years
Loose traces of babyhood, independent and active, muscle grow, high energy, curiosity, play/make friends, developing the sense of right and wrong
