(a) Humans and herbivores, such as the (b) rabbit, have a monogastric digestive system.
However, in the rabbit the small intestine and cecum are enlarged to allow more time to digest plant material.
The enlarged organ provides more surface area for absorption of nutrients. Rabbits digest their food twice:
the first time food passes through the digestive system, it collects in the cecum, and then it passes as soft
feces called cecotrophes. The rabbit re-ingests these cecotrophes to further digest them.
