Quotes by Ibn al-Nafis
The pursuit of knowledge is a continuous journey.
Truth is the ultimate goal of all inquiry.
The human body is a marvel of creation.
The physician must be humble in the face of the unknown.
The art of medicine is a divine gift.
The circulation of the blood is a continuous process, moving from the right ventricle to the lungs, where it mixes with air, and then returns to the left ventricle.
The heart has only two ventricles, not three as Galen claimed. The septum between them is solid and has no visible pores.
The pulmonary artery carries blood from the right ventricle to the lungs, and the pulmonary vein carries blood from the lungs to the left ventricle.
The blood is purified in the lungs, where it acquires a vital spirit.
The air that enters the lungs is not merely for cooling the heart, but for mixing with the blood.
The arteries carry blood, not air, as was previously believed.
The veins carry blood from the periphery to the heart.
The liver is not the source of blood, but rather a site for its formation and purification.
The brain is the seat of sensation and movement, and the source of nerves.
The eye is an organ of sight, and its structure is perfectly designed for this purpose.
The human body is a marvel of creation, and its intricate design points to a wise Creator.
Knowledge is a light that illuminates the path to truth.
The pursuit of knowledge is a noble endeavor, and it is incumbent upon us to seek it throughout our lives.
The physician must be a seeker of truth, and he must not be afraid to challenge established beliefs if they are found to be false.
The physician must have compassion for his patients, and he must treat them with kindness and respect.
