The gastric pits of the stomach open on to branching glands: pyloric glands in the antral part of the stomach; gastric or oxyntic (acid forming) glands in the fundus and body of the stomach. A schematic diagram of an oxcyntic gland is shown here (see also anatomy).
This resin code on a plastic container indicates that BPA may have been used in its manufacture. BPA is a chemical component present in polycarbonate plastic used in the manufacture of certain beverage containers and most food can liners. BPA-based plastic bottles are clear and tough.
BPA (bisphenol-A) is a chemical that is added to many commercial products, including food containers and hygiene products. It was first discovered in the 1890s, but chemists in the 1950s realized that it could be mixed with other compounds to produce strong and resilient polycarbonate plastics.
