If I could become a human body doctor and travel inside the human body, a 300-word essay

On a holiday morning, my mother took me to the Science and Technology Museum, where there was a very novel project called "Human Body Travel".

A huge mannequin stands in the exhibition hall. I got into the huge "human mouth", walked forward on the red "tongue", and entered the human chest through a thick pipe. I saw a fist-shaped heart hanging on the left, with many tubes of different thicknesses like branches extending from it. Mom said it was a coronary artery. The thickest tube is inserted into the dark brown wing-shaped parts on both sides, which are the human lungs. I walked forward and fell into a big soft bag. It turned out to be the stomach. Oh, I became the delicacy of the "giant"... I crawled around in the giant's mannequin, looked here and touched it. I can't get enough of it there.

When I got home, I pestered my mother and asked a lot of questions about the human body. Mom patiently explained what the internal organs were and what the muscles and bones looked like. Because she knew that I loved to get sick, she also specially talked about some knowledge about white blood cells fighting bacteria and protecting the human body. As she listened, I fell asleep...

In the haze, I turned into a small cell, We came to a completely unfamiliar place, surrounded by red and soft things everywhere. Isn’t this the human body? Without thinking too much, many of my companions and I were pushed forward by the huge pressure from our hearts, crowded forward in the long and narrow passage, and some strange-shaped things kept passing by me. At this time, someone shouted: "Brave white blood cell warriors, an enemy has invaded the tonsils, please join the battle immediately!" Hearing the call, I was surrounded by my partners and rushed forward involuntarily. After a difficult trek, a group of ugly and dirty germs appeared in front of us, and they were devouring healthy cells crazily. We white blood cell warriors came from all directions like a tide and launched a desperate struggle with the hateful germs. After a fierce battle, the germ cluster became smaller and smaller, and finally we eliminated them all. Although many white blood cell warriors died, victory ultimately belonged to us.

We health guards faithfully carry out our mission and maintain the health of the human body with our lives, because the human body is our home!

After the victory, I and all the white blood cell warriors cheered and shouted with joy... I kicked my legs hard, and I woke up. It turned out to be a dream! I couldn't help but feel funny. It was so interesting to think about my dream while lying in bed! What a wonderful journey of the human body! Thinking about it, I fell asleep again, with a smile on my face...
