    Think producing millions of sperm each day is complicated?
    ::每天产生数百万精子的想法很复杂吗?

    If producing millions of each day, as in the male reproductive system , is complicated, that is nothing compared to what must occur in the . This system is controlled by an intricate dance of , cycles, and events.
    ::如果像男性生殖系统一样,每天生产成百上千万的生殖系统是复杂的,那么与在该系统中必须发生的事情相比,这并不复杂。 这个系统是由复杂的舞蹈、周期和事件所控制的。

    Female Reproductive Structures
    ::女性生殖结构

    The female reproductive system consists of structures that produce female gametes called eggs and secrete the female sex hormone estrogen . The female reproductive system has several other functions as well:
    ::女性生殖系统由生产被称为蛋和女性性激素雌激素分泌的雌性多胞胎的结构组成。

    1. It receives sperm during sexual intercourse.
      ::它在性交期间接收精子。
    2. It supports the of a fetus .
      ::它支持胎儿。
    3. It delivers a baby during birth.
      ::它在婴儿出生时提供婴儿。
    4. It breast feeds a baby after birth.
      ::它在婴儿出生后喂奶。

    The main structures of the female reproductive system are shown in Figure . Most of the structures are inside the pelvic region of the body. Locate the structures in the figure as you read about them below. 
    ::女性生殖系统的主要结构在图中显示。大多数结构位于身体骨盆区域。

    Female reproductive organs including ovaries, uterus, and vagina.

    Female Reproductive Structures. Organs of the female reproductive system include the vagina, uterus, ovaries, and fallopian tubes.
    ::女性生殖结构:女性生殖系统的器官包括阴道、子宫、卵巢和输卵管。

    External Structures
    ::外部结构

    The external female reproductive structures are referred to collectively as the vulva . They include the labia (singular, labium ), which are the “lips” of the vulva. The labia protect the vagina and urethra , both of which have openings in the vulva.
    ::外部女性生殖结构统称为阴道,包括阴唇(阴唇、),即阴唇的“唇”,阴唇保护阴道和尿道,两者在阴道中都有开口。

    Vagina
    ::阴道

    The vagina is a tube-like structure about 9 centimeters (3.5 inches) long. It begins at the vulva and extends upward to the uterus . It has muscular walls lined with mucous membranes. The vagina has two major reproductive functions. It receives sperm during sexual intercourse, and it provides a passageway for a baby to leave the mother’s body during birth.
    ::阴道是一个管状结构,大约9厘米(3.5英寸)长,从阴道开始延伸到子宫,有肌肉壁,有粘膜,阴道有两个主要生殖功能,在性交期间得到精子,为婴儿在分娩期间离开母亲的身体提供了通道。

    Uterus
    ::尤特鲁斯

    The uterus is a muscular organ shaped like an upside-down pear. It has a thick lining of tissues called the endometrium . The lower, narrower end of the uterus is known as the cervix . The uterus is where a fetus grows and develops until birth. During , the uterus can expand greatly to make room for the baby as it grows. During birth, contractions of the muscular walls of the uterus push the baby through the cervix and out of the body.
    ::子宫是一种肌肉器官,其形状像一头倒转的梨子,其厚厚的内衬组织称为内宫。子宫的下端和狭端被称为子宫颈。子宫是胎儿生长和发育直至出生的地方。在子宫生长期间,子宫可以大大扩张,为婴儿提供空间。在分娩期间,子宫肌肉壁的收缩将婴儿推入宫颈和身体外。

    Ovaries
    ::阴流

    The two ovaries are small, egg-shaped organs that lie on either side of the uterus. They produce eggs and secrete estrogen. Each egg is located inside a structure called a follicle . in the follicle protect the egg and help it mature.
    ::这两个卵巢是小的蛋状器官,位于子宫两侧,它们产卵和雌激素,每个蛋都位于一个叫做卵囊的结构内,在卵囊中保护蛋,帮助其成熟。

    Fallopian Tubes
    ::瀑布管

    Extending from the upper corners of the uterus are the two fallopian tubes . Each tube reaches (but is not attached to) one of the ovaries. The ovary end of the tube has a fringelike structure that moves in waves. The motion sweeps eggs from the ovary into the tube.
    ::从子宫上角延伸出的是两个输卵管。每个输卵管都达到(但并不连接于)卵巢之一。管的卵巢端有一个波形结构。运动将卵子从卵巢中排入管子。

    The breasts are not directly involved in , but they nourish a baby after birth. Each breast contains mammary glands , which secrete milk. The milk drains into ducts leading to the nipple. A suckling baby squeezes the milk out of the ducts and through the nipple.
    ::乳房与乳房没有直接关系,而是在婴儿出生后喂养婴儿,每个乳房都含有乳房乳房,乳房有乳液,奶液排入通向乳头的管子,乳房里挤出奶液,乳房里挤出乳房,乳房里挤出乳房,乳房里挤出乳房,乳房里挤出乳房,乳房里排出乳房,乳房里排出乳房。乳房里排出乳房,乳房里排出乳房,乳房里排出乳房,乳房里排出乳房。乳房里排出乳房,乳房里排出乳房,乳房里排出乳房,乳房里排出乳房,乳房里排出乳房,乳房里排出乳房。
