...diagrams of the circulatory system?
Answers:
The circulatory system came to be understood in the 17th century. William Harvey (1578-1657) is the physician most commonly credited near the first description of the circulatory system. Others described components of the circulatory system before Harvey's time, however. Galen (born around 129 C.E.) is credited as the first to discover that arteries carried blood (previously thought to contain air). Iranian physician Abu Bakr Mohammad Zakariya al-Razi (865–925 C.E.) wrote a highly accurate anatomical description of the heart and blood vessels, and Ali ibn al-Abbas al-Majusi (known as Ahwazi), another Iranian physician (10th century C.E.), expounded a similar panorama to Galen regarding the circulation of blood. Physician and philosopher Ibn Al-Nafis Damashqi (1210–1285 C.E.) added to this knowledge when he described the pulmonary circulation. Harvey's description was the most complete, but did not explain the exchange of blood between arteries and vein away from the heart. In 1661, Italian anatomist Marcello Malpighi (1628 – 1698) described the capillaries, which completed the understanding of the circulation.
I would assume that one of these people have something to do with the whole red/blue thing but I hold been searching the internet for almost 30 minutes and I can't find anything about who first used those colors within diagrams of the circulatory system.
