Ibn al-Nafis was a brilliant Arab polymath.

A polymath is a person who studies many different subjects. He worked in medicine, surgery, biology, and even philosophy. He is best known for his work on how blood moves. Many people call him the father of circulatory physiology. This means he studied how the body's systems move blood around. His ideas changed how we understand the living body. He was so smart that some called him the "second Avicenna."

Before Ibn al-Nafis, most doctors followed the ideas of a Greek physician named Galen.

Galen thought blood moved through tiny, invisible holes in the heart. Ibn al-Nafis did not believe this was true. He used animal dissection to see how bodies really worked. He discovered pulmonary circulation. This is the way blood moves from the right side of the heart to the lungs. He also found early clues about coronary and capillary circulations. Capillaries are the tiny tubes that carry blood through the body.

Ibn al-Nafis was born in Damascus between 1210 and 1213. He began studying medicine at age 16 at the Nuri Hospital. He studied there for more than ten years. Later, in 1236, he moved to Egypt. He worked under the Ayyubid sultan al-Kamil. In Egypt, he became a chief physician at several hospitals. He served at al-Naseri Hospital and later at al-Mansori Hospital. He even became a personal doctor to leaders like Sultan Baibars.

This scholar was a very busy writer. He wrote more than 110 volumes of books. One of his biggest works was an encyclopedia called Al-Shamil fi al-Tibb. He wanted to write 300 volumes, but he finished 80 before he died. This book was a huge summary of all medical knowledge in the Islamic world. He also wrote a famous book at age 29. It was a commentary on anatomy. This book helped him challenge the old ideas of Galen and Avicenna.

His work helps us understand how doctors learn today. Ibn al-Nafis used observation to prove his ideas. He did not just guess; he looked at real bodies. This is how modern science works. He also studied how diseases spread in cities. He once made a map to find where a sickness started in Damascus. This is very similar to how doctors track outbreaks today. His life shows how much we can learn by asking questions and looking closely.
