陰道
位置、形態與功能
陰道（vagina
拉丁語：鞘）為一從子宮頸延伸到外開口的、長約3
1/2的肌性管道。其外開口叫陰道口，為陰戶的組成部分。陰道有三個主要的功能：
|
|
1.為月經從子宮排出體外提供通道。
2.為男子的陰莖及其射出精液的容器（此處的描述疑為不妥，可以改為“為性交時的交接器官和容納精子”——譯者注）。精子然後可以借道進入子宮頸。
3.
在分娩時為胎兒從子宮通往外部提供通道。

The Vagina
Location, form and function
The vagina (lat.: sheath) is a muscular tube about 3 1/2 inches long extending from the cervix to an external opening which is part of the vulva. The vagina serves three main functions:
|
|
1. It provides a passageway for the menstrual flow from the uterus to the outside.
2. It serves as a receptacle for a man's penis and his ejaculated sperm which
then may move on through the cervix.
3. It provides a passageway for the baby during birth from the uterus to the outside.
