What the hell is auntie! Why do you visit every month?

Sisters, do you know the aunts who visit every month? Why does she chatter so often? Why do we worry again if she doesn't come? Today, Xiaozhu came to tell everyone about this cute and hateful aunt Sang. Aunt Sang is the result of the cycle of female menstrual cycle, and usually visits once every 21 to 35 days. Recalling the first time I came to my aunt Sang, it was a terrifying memory. In fact, my aunt was controlled by the brain! A female's uterus is like a small pear-shaped pocket with its mouth facing downwards, and the outlet is usually 'blocked'. On the inner wall of the pocket, there is a thin membrane called the endometrium, which has the ability to grow and peel off periodically. Many tiny blood vessels grow in the endometrium. When they receive instructions from the brain, they carefully transport the oxygen and nutrients needed for the growth of the endometrium to help the endometrium grow thicker and thicker. The purpose is Prepare for conception. When these tiny blood vessels work conscientiously for about a month, the brain will order them to 'stop work' and no longer need to transport oxygen and nutrients. After finishing the mission, they 'blowed' and bleeds. At this time, the endometrium broke into many small fragments and peeled off from the inner wall of the uterus. When these blood and endometrial fragments mix with these other components, flow out of the cervix and then out of the vagina, they become our aunts of love and hatred! When the aunt leaves, the endometrium will start to grow thick again and circulate again and again. So, Aunt Sang visits us every once in a while, it's the brain commander! The ovaries are responsible for 'uploading and distributingThe ovaries secrete estrogen and progesterone, allowing these two hormones to alternately dominate our body, and what we can perceive is the wave after wave of aunts produced by the uterus!
