Erasistratus denies that the stomach exerts any pull in the act of swallowing. That he is wrong, however, is proved by the anatomical structure of the stomach--its inner coat with longitudinal fibres obviously acts as a _vis a fronte_ (attraction), whilst its outer coat exercises through the contraction of its circular fibres a _vis a tergo_ (propulsion); the latter also comes into play in vomiting. The stomach uses the oesophagus as a kind of hand, to draw in its food with. The functions of the two coats proved also by vivisection. Swallowing cannot be attributed merely to the force of gravity.
