What happens to food once it leaves the gizzard?
The ground-up food enters the worm’s intestine, which secretes digestive enzymes to chemically break down molecules of food nutrients. These simplified nutrients then pass through the intestinal wall for absorption into the bloodstream, and are carried where needed. Undigested material, including soil, bacteria, and plant residues, passes out of the worm through its anus as worm castings.
