|Question/Main Ideas |TOPIC: Female Reproductive System (5d) |
| | |
|What is Female Reproduction? |The reproductive organs of the human female generate eggs and sexual activity may lead to |
| |fertilizationan pregnancy. |
|What is puberty? | |
| |The time of life when male and femal sex organs become mature. |
| |-At puberty, a woman begins to ovulate. |
| |[pic] |
| |is the release of a mature egg from the ovary for pssible fertilization. |
| | |
| |About two weeks into the cycle around the 14th day of a woman’s menstrual cycle. |
| | |
| |In the Ovaries. The ovaries are about the size of a large olive. [pic] |
| |A female reproductive organ in which ova or eggs (Oocytes) are produced. The woman has an estimated|
| |300 to 400 thousands of eggs contained within her ovaries at the time of puberty. |
| | |
| | |
| | |
| | |
| |Also make sex hormones called Estrogen and Progesterone. The sex hormones regulate the release of |
|What is when a female ovulate (ovulation)? |eggs and direct the development of female traits. |
| | |
|When does Ovulation occur? |In a structure of the ovary called a follicle. During ovulation, a mature follicle ruptures (break)|
| |through the ovary wall. |
|Where does ovulation take place? |[pic] |
| |[pic] |
| | |
| |Once release, the egg travels down on of the fallopian tubes that lead to the uterus. |
| | |
| |Is the organ where a baby can grow and develop. |
| |[pic] |
| |is the passageway that receives sperm during sexual intercourse. |
|What are Ovaries? |[pic] |
|[pic] |If the female, at or around the time of ovulation, engages in sexual activity that results in sperm|
| |being deposited in or near the vagina, a sperm cell can travel through the vagina to the uterus or |
|What else do the Ovaries do? |Fallopian tubes and fertilize the egg. |
| | |
| | |
|Where do the eggs mature? |A fertilized egg begins a 5-day journey down the fallopian tube toward the uterus. During the |
| |journey, the zygote undergoes any mitotic divisions. By the time it reaches the uterus, it is an |
| |embryo that looks like a tiny ball of cells. |
| | |
| |is when the tiny embryo becomes embedded in the lining of the mother’s uterus. Once the embryo is |
| |implanted, pregnancy begins. |
| |[pic] |
| |1. Each month, starting at puberty, the tissue lining the uterus thickens to prepare for pregnancy.|
| | |
| |2. If the fertilized egg fails to implant (attach) and begin development, or if the egg is not |
|What is the pathway of the egg? |fertilized, it will be sloughed off along with several layers of cells lining the uterus and leave |
| |the female’s vagina during menstruation. |
|What is a Uterus? |3. if fertilization does not occur, the egg deteriorate; and the tissue layers along with the |
| |deteriorated egg, is discharged through the vagina. |
| |4. Menstruation last about 5 days after which the tissue lining the uterus again thickens. |
| |5. This cycle repeats each month from puberty until middle age. |

| | |
| | |
| | |
| |One of the first signs of pregnancy is that a woman’s regular menstrual cycle stops. |
| |A pregnant woman may give birth to a baby between 38 and 42 weeks later. |
|What is the Vagina? |[pic] |
| |At the 8th week, the embryo has developed enough to be called a fetus. |
| |The human fetus develops from the end of the 8th week of pregnancy (when the major structures have |
| |formed) until birth. |
| |After 38 to 42 weeks, the fetus is ready to live outside of the mother. |
| |The mother goes through a series of contractions called LABOR. |
| |The fetus is pushed, headfirst, through her vagina. |
| |The baby is sill connected to the placenta by the umbilical cord. |
| |When the doctor ties and cut the umbilical cord, birth is complete. |
| |The mother’ continues with labor until the placenta is pushed out of her body. |
| | |
|How does Fertilization occur? |Organ that connects the developing fetus to the uterine wall. |
| |Supplies food and oxygen from the mother’s blood to the developing embryo. |
| |It contains a network of blood vessels that links the embryo to the mother. |
| |A thin, protective membrane called the Amnion surrounds it. |
| |Inside the amnion and surrounding the embryo, is Amniotic Fluid, which protects the embryo from |
|What is the pathway of fertilized egg? |shocks. |
| | |
| | |
| |The growing fetus gets all of its oxygen and nutrients directly enters the embryo’s body from its |
|What is implantation? |mother’s blood supply through the placenta and umbilical cord. The blood of the mother and fetus do|
| |not mix together. Waste products like carbon dioxide also pass from the fetus to the mother’s blood|
| |for removal. The umbilical cord contains arteries and veins that connect the embryo to the |
| |placenta. |
| | |
| |Produces eggs, ensure development of fertilized eggs, and give birth. |
