उत्तर
The given dentition is that of a herbivore because there are no canines present in the dentition. Canines are required by carnivores as they help in holding and tearing of food. The teeth of herbivores are used for cutting, gnawing, and biting, while the teeth of carnivores are sharper and more suited for catching, killing and tearing the prey.

How is the small intestine designed to absorb digested food?
Where is the bile produced? Which component of the food does it help to digest?
| The partially digested food coming from the stomach of a person enters a long and narrow organ A in his body. The organ A receives the secretion of two glands : liver and pancreas. Liver secretes a greenish-yellow liquid B which is normally stored in the organ C. Pancreas secretes pancreatic juice which contains three digestive enzymes D, E and F. The intestinal juice completes the process of digestion of food. The inner wall of organ A has millions of tiny finger-like projections G which help in the rapid absorption of digested food into blood stream. The undigested part of food then passes into wider tube H which absorbs most of the water from undigested food. The last part of tube H called I stores this undigested food (or waste) for some time. The undigested food is then passed out though opening J as faeces in the process known as K. |
