Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body’s tissues through the aorta.

Galen’s theories about the blood circulation, however, were well off the mark and it was not until the 17th century that the great English physician William Harvey would challenge Galen’s ideas in this regard. With Hippocrates who preceded him by some 500 years, Galen was preeminent among the most distinguished physicians of antiquity.
When did Galen publish his theory of the circulatory system?
Galen’s theory of the physiology of the circulatory system remained unchallenged until ca. 1242, when Ibn al-Nafis published his book Sharh tashrih al-qanun li’ Ibn Sina ( Commentary on Anatomy in Avicenna’s Canon ), in which he reported his discovery of the pulmonary circulation.
Why was Galen so important to the church?
Galen’s books were important because many people could not read, so any doctor who had read them was considered very intelligent. What made Galen hard to challenge? There was a lack of scientific evidence to challenge what Galen taught, because the Church would not allow human dissection.
