Did you know?
Gastr- comes from the Greek word for "belly", and shows up in English in such words as gastric ("relating to the stomach") and gastronomy ("the cooking and eating of fine food"). Believe it or not, there are many people today who have had a gastrectomy and live without a stomach; some of them need to eat fairly steadily and carefully through the day, but many lead almost completely normal and even vigorous lives.
