A basic explanation of the purpose and process of menstruation, told largely wit
Plot Summary:The story of menstruation begins, as the motherly narrator informs us, with the pituitary gland - a gland at the base of the brain that sends hormones throughout the bloodstream that order growth. When a girl reaches an age somewhere between 11 and 17 - the average is 13 - the pituitary gland sends maturing orders to the ovaries, which in turn order the uterus to create a thickened lining, filled with watery fluids and blood. If an egg is fertilized it will remain within that thickened lining for nourishment. But if the egg is not fertilized, the body has no use for the extra nourishment, and it passes out of the body - which is the process called menstruation. The narrator proceeds to disprove taboos against bathing or exercise during menstruation. She advises that girls should keep a calendar that keeps track of the number days between periods. And she notes how good posture, healthy foods and positive attitudes can affect the menstruation cycle.
太无聊了😭
values outdated.
在哪看呢
特别喜欢老动画,即便仅仅只是讲大姨妈……
我还真学到了东西。但这老画质也太cult了,而且为什么女孩子们都没有脚?!!而且已经cult和昏暗到,看到一多半的时候,我突然真的就闻到浓浓浑浑的血腥味了。
