1 A female's internal reproductive organs are the vagina, uterus, fallopian tubes, and ovaries. The vagina is a muscular, hollow tube that extends from the vaginal opening to the uterus.The vagina serves 3 purposes:a. It's where the penis is inserted during sexual intercourse,b. It's also the pathway that a baby takes out of a woman's body during childbirth, called the birth canalc. It provides the route for the menstrual blood (the period) to leave the body from the uterus.
2 The vagina connects with the uterus, or womb, at the cervix (which means neck). The cervix has strong, thick walls.The uterus is shaped like an upside-down pear, with a thick lining and muscular walls.These muscles are able to expand and contract to accommodate a growing fetus and then help push the baby out during labor.
3 At the upper corners of the uterus, the fallopian tubes connect the uterus to the ovaries. The ovaries are 2 oval-shaped organs that lie to the upper right and left of the uterus. They produce, store, and release eggs into the fallopian tubes in the process called ovulation.
4 When an egg pops out of an ovary, it enters the fallopian tube When an egg pops out of an ovary, it enters the fallopian tube. Once the egg is in the fallopian tube, tiny hairs in the tube's lining help push it down the narrow passageway toward the uterus.The ovaries are also part of the endocrine system because they produce female sex hormones such as estrogen and progesterone
5 In females, hormones (estrogen and progesterone) leads to development of secondary sex characteristicsa. Widening of hipsb. Development of breasts
6 What Does the Female Reproductive System Do? The female reproductive system enables a woman to:produce eggs (ova)have sexual intercourseprotect and nourish the fertilized egg until it is fully developedgive birth

10 Sperm is deposited within 5. Why does the lining of the uterus thicken during the first half of the menstrual cyclea. To provide a place for sperm cells to attachb. To produce a mature egg cellc. To prepare to nurture an embryod. To rid the body of unfertilized egg cellsovariesSperm is deposited withinProduce eggs & hormonesEgg is fertilizedEmbryo develops into the fetus
11 The functions of female reproductive are: Produce mature egg cellsAllow for internal fertilizationSupport internal developmentIf an egg cell is not fertilized after it is released it breaks down and is passed from the body. This is known as ________________The lining of the uterus thicken during the first half of the menstrual cycle to prepare to nurture an embryo
