What was erasistraus theory?

Answer 1

Erasistratus, a Greek physician of the Hellenistic period, proposed a theory that emphasized the role of the heart in the circulatory system and the importance of the brain in regulating bodily functions. He suggested that the heart was the center of the body's vital heat and that blood vessels carried both blood and air, which he believed were essential for life. Erasistratus also distinguished between arteries and veins, although his understanding of the circulatory system was not entirely accurate by modern standards. His work laid the groundwork for future anatomical studies and the understanding of physiology.
