THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Because the rabbit does not regurgitate its food and chew the cud, but does rely on gut fermentation and caecotrophy for its nutritional wellbeing, this herbivorous species is sometimes referred to as a “pseudo-ruminant”.

Detailed explanation-2: -Rabbits are monogastric hindgut fermenters and require a high-fiber diet (between 14–20%). As a prey species, they rely on the rapid transit time of their unique digestive system to keep their body size and weight low, enabling them to be fast-moving and nimble.

Detailed explanation-3: -The object of coprophagy or pseudo-rumination is presumably to provide the rabbit with a supply of bacterial protein and possibly with the vitamin B complex which it would otherwise lose.
