What is the importance of the gastric lumen and gastric pits in the stomach?

Small pores called gastric pits contain many exocrine cells that secrete digestive enzymes and hydrochloric acid into the lumen, or hollow region, of the stomach. Mucous cells found throughout the stomach lining and gastric pits secrete mucus to protect the stomach from its own digestive secretions.

You should check out the situation and then ask questions like “are you choking”? and if they are able to respond they should nod and if they are not making sound do the heimlich maneuver. i hope this .
