Circulation finder

The discoverer of blood circulation is the Arab scientist Ibn al-Nafis, who was born in Damascus in 1213 AD, and died in Cairo in 1288 AD. Ibn al-Nafis was a prominent scholar of medicine, philosophy, and science, who studied under many of the prominent scholars of his time, such as Ibn Rushd and Ibn Sina.

In 1242 AD, Ibn al-Nafis published his famous book “Al-Shamīl fi al-Sina’ al-Mīdina,” which included his discovery of the microcirculation of blood. Ibn al-Nafis proved in this book that blood leaves the heart to the lungs, where it is purified with oxygen, and then returns to the heart again to be pumped throughout the body.

Ibn al-Nafis' discovery of blood circulation was a major scientific achievement, as he proved that blood circulates in the body in a closed cycle, and not as scientists thought before him, which is that blood moves from the heart to the extremities and then returns to the heart again through the pores in the barrier between... Ventricles.

Ibn al-Nafis' discovery of blood circulation did not gain international recognition until centuries after his death, as it was the English scientist William Harvey who became famous for discovering blood circulation in the seventeenth century. However, Ibn al-Nafis is today considered the true discoverer of blood circulation, and one of the greatest Arab scientists who influenced the development of medicine and science.

Here is some evidence that proves that Ibn al-Nafis was the discoverer of blood circulation:

* Ibn al-Nafis, in his book “Al-Shamil fi al-Sina’ al-Medika,” accurately described the microcirculation, proving that blood leaves the heart to the lungs and then returns to the heart again.

* Ibn al-Nafis conducted anatomical experiments on animals to prove the validity of his theory about blood circulation.

* Ibn al-Nafis was a prominent scholar of medicine and science, and had extensive knowledge of human anatomy.

Based on this evidence, it can be said that Ibn al-Nafis is the true discoverer of blood circulation, and is one of the greatest Arab scientists who influenced the development of medicine and science.

Who is Ibn al-Nafis?
