The text appears to be a script for an animated educational video about the human immune system. The story follows two main characters, Krosh and the Hedgehog, who shrink down to a tiny size and enter the body of a person named Pina, who has fallen ill due to a virus.
As they navigate through Pina's body, they meet various cells and microorganisms, including leukocytes, phagocytes, and lymphocytes, which are part of the immune system. Along the way, they learn about the different ways the body defends against viruses and other pathogens.
The video aims to educate viewers about the immune system, how it works, and the importance of vaccination in preventing the spread of diseases. The story is presented in a fun and engaging way, with the two main characters facing various challenges and obstacles as they try to help Pina recover from her illness.
Throughout the script, there are also references to real-life scientists and their discoveries related to the immune system, including Ilya Mechnikov and Paul Ehrlich, who received the Nobel Prize in 1908 for their work on immunity.
Here are the key facts extracted from the text:
1. Everyone was told to get vaccinated.
2. Adrenaline is a substance in the body.
3. The body has a defense system against viruses.
4. Leukocytes are a type of white blood cell that fights viruses.
5. Lymphocytes are a type of white blood cell that releases antibodies to fight viruses.
6. Phagocytes are a type of white blood cell that eats viruses and bacteria.
7. Antibodies are special marks that stick to viruses and bacteria, making them noticeable to other white blood cells.
8. The skin is the first line of defense against microbes, bacteria, and viruses.
9. The stomach has hydrochloric acid that kills microbes that enter the body.
10. Tears contain substances that are destructive to bacteria.
11. The circulatory system has the least number of leukocytes.
12. The spleen has the most leukocytes.
13. Viruses are constantly changing and mutating, making it difficult for the body to fight them.
14. Vaccination helps the body to fight viruses by introducing a small, harmless amount of the virus to the body.
15. Lymphocytes remember viruses and can fight them more efficiently the next time they enter the body.
16. Ilya Mechnikov and Paul Ehrlich received the first Nobel Prize for the study of immunity in 1908.
17. Ralph Steinman and Jules Hoffman received the Nobel Prize for the study of innate immunity in 2011.
