Spider Esophagus

We've learned about the spider's cephalothorax, where they have fangs in their chelicerae, and the parts that are almost like small arms by their mouth called pedipalps

Spiders don't have teeth, so they can't chew food up like humans do.
They use their fangs to kill small insects with venom.

When humans eat food, it goes into our stomachs where some things called enzymes help turn our food soft and mushy.

Spiders actually spit out some of those enzymes right onto the insects that they've killed, and then when the enzymes turn their food to mush they suck it up into their mouth to go down their esophagus into their stomach.
