“Even breathing is content” The breathtaking live broadcast of Pyepo TV begins!
From suffocation and hyperventilation to hiccups, uncover the secrets of your respiratory system!

Somaek, who was busy brushing his teeth because he didn't want to go to the dentist again, swallowed the toothpaste and then started coughing violently, which caused him to hyperventilate.
The respiratory organs of the human body, caught in the heavy breathing, rush to respond urgently, but recovery is not easy.
In particular, popular YouTuber Pyepo and the Studio Oxygen production crew, who were preparing a special live, are swept away by a tornado-like wind that enters their lungs... Will Somaek be able to breathe comfortably again? And will Pyepo TV's special live, now in disarray, go on as planned?

Based on the popular video "A Day in the Life of Human Friends," which has approximately 63 million views, the "Human Friends of the SomackGuffin" series features original stories and new human characters in each volume.
In Volume 5, the alveoli, where oxygen and carbon dioxide are exchanged, as well as the various organs in the nose, mouth, and throat, appear as characters with their own unique characteristics, conveying knowledge about the human body in an easy-to-understand way through interesting topics related to breathing, such as coughing, snot, and hiccups.
Finding the names of human friends in a word board, along with a letter puzzle and true/false quiz, is both educational and fun.

Linked to elementary science curriculum
Korea's first medical gag cartoon series!

This book contains key information from the 6th grade, 2nd semester elementary science course, 'Structure and Function of Our Body.'
You can naturally learn about the definition of breathing, the shape and function of the respiratory organs, and the structure of the lungs.
Not only that, you can easily understand the content you learn in the human body section of middle and high school science textbooks.
This is because the contents of the nose, mouth, epiglottis, vocal cords, trachea, bronchi, alveoli, and diaphragm are incorporated into cute and vivid characters and a hilarious story.

Knowledge that could not be conveyed through the comics was covered in detail on the information page, so you did not miss out on in-depth learning.
From interesting topics like "Phlegm comes from the bronchi?" and "Why do we have two nostrils?" to essential knowledge like "The Principles of Breathing" and "The Structure of the Lungs," this book provides helpful explanations and illustrations so you can acquire solid knowledge of the respiratory system in just one book.
To avoid any misunderstandings due to the cartoonish expressions, we have included a 'True or False' corner to provide accurate information.
