Chapter 67： Physical Health Section 2

So one day, after school, Cheng Zhiyan was mysteriously shouted into the study by her mother and her mother.

As soon as he entered the study, he saw a small blackboard on the wall, and Mother Bunny and her mother looked at me with a mysterious expression on both sides of the blackboard.

"Mom, aunt, call me something?" Cheng Zhiyan looked at them and asked.

"Cough, what's that." Cheng Zhiyan's mother coughed awkwardly a little, then straightened up: "Yes, you have grown up now, and have some knowledge, Mom thinks I should tell you."

"Oh ... what knowledge?" Cheng Zhiyan took the opportunity to sit down on the small chair in front of the blackboard and asked casually: "So you called me today to teach me?"

"That's right." Cheng Zhiyan's mother nodded, then turned her head and winked at Mother Rabbit, indicating that she could start.

Mother Bunny walked to the blackboard with a stack of papers in her hand, pasted them one by one, then turned around and smiled at Cheng Zhiyan: "Say, today, my aunt will tell you something , How the baby was born. "

Cheng Zhiyan: "..."

"Ahem, my aunt turned over your" Health Education "textbook two days ago and found that it didn't say anything about how to have a baby, so it seems that the school did not teach you this knowledge, so the aunt came to you Explain, how about it? "Mother Bunny's face was full of smiles, but in fact there were all kinds of panic in her heart. This is the first time in her life that she has given physiology education to others! !!

"Auntie, please." Cheng Zhiyan sat down in the small chair, straightened his back, and looked at the mother bunny standing in front of the small blackboard.

"First, let's take a look at the body structure of boys and girls ..." Mother Rabbit reached for the first picture affixed to the small blackboard, and painted a naked boy and a small boy in cartoon characters. girl.

"So ... after the first holiday, the girl indicates that she has fertility. Before the next holiday, there will be a process of ovulation. Of course, this egg is inside the girl's belly ..." Sweating, speaking hard to Cheng Zhiyan.

Cheng Zhiyan was silent for a moment, then suddenly raised his hand and said, "Auntie."

"Is there anything wrong with the speech?" Mother Bunny quickly interrupted her explanation and asked him.

"After the ovulation, the secondary oocytes in the second stage of mature division of the female, along with the surrounding zona pellucida and radioactive crowns, enter the fallopian tube ampulla through the abdominal cavity due to the cilia of the fallopian tube epithelial cells and the contraction of the muscular layer. It should be generalized into the belly of a girl, right? "Cheng Zhiyan made his opinions very seriously.

Mother Bunny, Cheng Zhiyan's mother, was stunned instantly.

After a long while, the mother bunny reached out and wiped the sweat on her forehead, and said to Cheng Zhi: "Say you ... know?"

"I know." Cheng Zhiyan nodded calmly.

"But in your school's" Health Education "textbook, there is no such paragraph ..." Mother Rabbit said weakly.

"Auntie has a" Family Doctor "on your bookshelf. I read it before when I was bored." Cheng Zhiyan replied casually.
