Mastication refers to the act of chewing food in the mouth before swallowing.

Digestion refers to the breakdown of food molecules into their individual components in order to extract nutrients for the body's use.

The function of the mouth in digestion is mainly the mechanical breakdown of food through cutting, crushing, and grinding by the teeth, along with moistening the food with saliva. It does not play a role in absorbing nutrients, producing enzymes, or controlling the movement of food through the digestive system.

The tongue primarily functions in moving food around in the mouth and providing taste sensation during eating. It does not produce enzymes, absorb nutrients, or play a direct role in swallowing food.

The correct label for the figure is v. large intestine. The large intestine is responsible for absorbing water from the remaining indigestible food matter and transmitting the useless waste material from the body.

Canine teeth are pointed and sharp, which helps in tearing food during the chewing process.

Premolars and molars are the teeth that are responsible for grinding and crushing food into smaller pieces for easier swallowing and digestion.

Saliva is composed primarily of water, with 99% water content.
