Stomach lining with gastric pits, SEM

Référence de la vidéo 11921584
Stomach lining. Coloured scanning electron micrograph (SEM) of the inner lining of the stomach (gastric mucosa). The large folds are known as rugae, and are present when the stomach is empty and contracted, but flatten out when full. The small indents are gastric pits. These contain cells that secrete enzymes, mucous and hydrochloric acid into the stomach.
