What are the accessory digestive organs?
The accessory digestive organs are teeth, tongue, salivary glands, liver and gall bladder, pancreas, and paranasal sinus.
What are the functions of the mouth?
The functions of the mouth include prehension and mastication, providing an alternate or supplemental airway, facilitating communication, defense, and vocalization.
What is the form of the mouth related to?
The wide gape of the mouth is related to the dog's role as a predator, enabling the use of teeth to secure prey and rapid consumption of large pieces of food.
