what kind of human digestive system have: omnivores or herbivores or carnivores?

Humans have a digestive system that shares features with both omnivores and herbivores, but is distinctly different from carnivores, with a long and sacculated intestine similar to herbivores for digesting plant matter, but also the capacity to digest meat. The human digestive system is considered omnivorous, meaning it is adapted to process a diet of both plant and animal matter, not exclusively one or the other.
Giant pandas have carnivore-like digestive systems despite their bamboo-heavy diet. They possess a relatively simple and short gastrointestinal tract, similar to other carnivores, and lack the necessary gut bacteria and enzymes to efficiently extract nutrients from plant matter. This carnivore-like anatomy and physiology make the giant panda a unique case, reflecting its evolutionary history as a member of the order Carnivora, which includes bears.
A giant panda eats a large amount of bamboo each day, consuming between 12 to 38 kilograms (26 to 84 pounds) to meet its energy needs, as bamboo is low in nutritional value and the panda's digestive system isn't optimized for processing it. Pandas spend a significant portion of their day, sometimes up to 14 hours, eating to compensate for the low nutritional content of bamboo.
They weigh between 70 kg (150 lb) and 125 kg (276 lb). The average weight for adults is 100 to 115 kg (220 to 254 lb). The giant panda's paw has a digit similar to a thumb and five fingers; the thumb-like digit – actually a modified sesamoid bone – helps it to hold bamboo while eating.
