Presentation Transcript

  1. Pregnancy

  2. Sexual Intercourse • The reproductive process in which the penis is inserted into the vagina and through which a new human life may begin

  3. Fertilization/Conception • The union of the egg and sperm that takes place in the fallopian tubes

  4. Zygote • The genetic material of the egg and sperm combined to form one cell

  5. Implantation • The attachment of the fertilized egg to the uterus • The egg is now known as a blastocyte, attaches to one of the walls in the upper 1/3 of the uterus • This happens within 3 to 5 days of fertilization • Once implantation has happened a women is said to be pregnant

  6. Implantation

  7. Embryo • The term for a developing pregnancy from fertilization to the end of week eight

  8. Endometrium • The lining of the uterus

  9. Placenta • An organ that develops in the uterus during pregnancy • The placenta provides nourishment and oxygen to the growing baby and removes waste • Some refer to it as the afterbirth because it is excreted from the body following the birth of the baby • Most substances are passed from the mother through the placenta to the baby

  10. Amniotic Fluid • The watery substance that surrounds the growing fetus during its time in the womb • The fluid helps to cushion the baby from outside force

  11. A medical procedure used for prenatal diagnosis, in which a small amount of amniotic fluid is extracted from the amniotic fluid around a developing fetus It is usually offered when there may be an increased risk for genetic defects in the pregnancy. Early amniocentesis can be performed as early as 13 weeks gestation Standard amniocentesis is usually performed between 15 and 20 weeks gestation Amniocentesis

  12. Ultrasound • used to visualize the embryo or fetus in its mother's uterus (womb) • The procedure is often a standard part of prenatal care, as it yields a variety of information regarding the health of the mother and of the fetus, as well as regarding the progress of the pregnancy.

  13. Umbilical Cord • A hollow rope-like tube that connects the embryo to the placenta • The placenta carries nutrients and oxygen to the baby and takes waste away

  14. First Trimester • The 1st 14 weeks of pregnancy • The most important trimester because this is when the vital structures are forming • The embryo develops all of its organs and grows to about 1.5 inches • The heart, brain, lungs, eyes, arms, and legs have formed – not all of them are fully functional • The placenta and umbilical cord are also formed during this time

  15. Second Trimester • Months 4-6 of pregnancy • The organs continue to develop and movement can be felt by month 4 • The heartbeat can be heard • The fetus recognized voices and it grows hair and nails • By the end of the 2nd trimester the fetus is about 14-15 inches long and about 2 pounds

  16. Third Trimester • Months 7-9 of pregnancy • The fetus gains most of its weight during this trimester and is able to grasp objects as well as open and close its eyes

  17. Fetus • A developing human, from the start of the ninth week of pregnancy until delivery

  18. Labor/Natural Birth • the culmination of a human pregnancy with the emergence of a newborn infant/s from the mother's uterus. • Natural Birth which is most common is when the baby is delivered through the vagina • First stage: contractions/dilation • Second stage: delivery • Third stage: placenta/afterbirth

  19. Labor/Natural Birth

  20. Breech Birth • refers to the position of the baby in the uterus such that it will be delivered buttocks first as opposed to the normal head first position.

  21. Caesarean Birth • A caesarean section or c-section, is a form of childbirth in which a surgical incision is made through a mother's abdomen and uterus to deliver one or more babies • It is usually performed when a vaginal delivery would put the baby or mothers life at risk, although in the last decade it has been performed upon request.

  22. Vernix • Vernix is the waxy or "cheesy" white substance found coating the skin of newborn humans • Vernix is the Latin word for "varnish." The vernix (or "varnish"), "varnishes" the baby. • Vernix is composed of sebum (the oil of the skin) and cells that have sloughed off the fetus' skin.

  23. Fontanelle • Fontanelles are soft spots on a baby's head which, during birth, enable the soft bony plates of the skull to flex, allowing the head to pass through the birth canal • Fontanelles are usually completely hardened by a child's second birthday, and will eventually form the sutures of the neurocranium.
