Document Summary
Galen of pergamum (139-200ad) developed an integrated physiological theory. Began his career as a physician to the gladiators, and carried out studies of barbary apes to better understand anatomy. Useful part was transported from the intestine via the portal vein to the liver and transformed into dark venous blood. Tissues could suck up the nutrients they needed as it was transported from the liver by veins. Useless part of the food was converted into black bile by the spleen. Galen was considered the authority of medicine for some 1200yrs even though by the (cid:373)iddle ages (cid:373)edical schools showed that circulatio(cid:374) did(cid:374)"t work this way. He was the king"s physician for james i and then charles i of england. Showed blood was moved in the arteries and veins by pumping of the heart. The heart was a muscle an movement is contraction not dilation. Heart beat was what created continuous circular motion of the blood.
