on part of the tract is called that way but it is different from our stomach
Explanation:
Stomach in humans is a pocket where digestion take place. For spiders, disgestion is done outside it's body, inside it's prey through the help of it's venom. They have no use for a stomach like ours but one pocket is called stomach in the spider's digestive tract: the "Sucking stomach" (fig 27)
This pocket is linked to different muscles that can be activated as a pump in order to absorb fluides from the mouth to the digestive tract.
