Erasistratus [b. Chios (Greek Aegean island), c. 304 bce, d. Mycale (Samsum Daği, Turkey), c. 250 bce] performs public dissections. He declares that veins and arteries are connected and that arteries carry air from the lungs to the heart, where they become "animal spirits" that are carried from the heart to the rest of the body, while the veins carry blood. He observes that the nerves are connected to the brain and believes that there is a "nervous spirit" carried by them to the body. See also 450 bce Medicine & health; 1240 Medicine & health.

Year 275 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Dentatus and Caudinus (or, less frequently, year 479 Ab urbe condita). The denomination 275 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
