Ibn al-Nafis

Hello. My name is Ibn al-Nafis, and I was a doctor who lived a very long time ago. I was born around the year 1213 near a beautiful city called Damascus. Even when I was just a boy, my mind was always buzzing with questions. I loved to learn about everything, but I was most curious about the amazing human body. I wanted to understand how it all worked, from our blinking eyes to our beating hearts. I spent my days reading, studying, and asking questions that no one had thought to ask before. My curiosity was like a little seed that would one day grow into a very big discovery.

When I grew into a young man, I knew I had to keep learning. So, around the year 1236, I moved to the big, bustling city of Cairo in Egypt. It was a very exciting place filled with new things to see and learn. I became a doctor and began working at a famous hospital called the Al-Nasiri Hospital. My job there was very important. I helped people who were sick feel better and get strong again. I was also a teacher. I loved showing my students everything I knew, so they could grow up to be wonderful doctors who could help many other people, too.

While I was working as a doctor and a teacher, I kept studying the human body. For hundreds of years, everyone, including the most famous doctors, believed that blood moved from one side of the heart to the other through tiny, invisible holes. But the more I studied, the more I thought that this idea just didn't make sense. Around the year 1242, I made a very big discovery. I realized there were no secret holes at all. Instead, the blood travels on a special path from the heart to the lungs to get fresh air. Then, it goes right back to the heart, which pumps this fresh blood all around the body. This was a brand new idea that helped everyone understand how our bodies really work.

I lived a very long and full life, writing many books about medicine and helping countless people as a doctor and teacher. I lived to be about 75 years old and passed away in the year 1288. My discovery about how blood flows through the lungs was a very important step in understanding the human body. It helped doctors for hundreds of years after my time, and it is still a key part of what we know about our amazing bodies today.
