Test: Teeth and Digestive System - 2 - Class 4 MCQ

Canines are sharp and pointed teeth located next to the incisors, and they are primarily used for tearing food. There are a total of four canines in the mouth.

The pulp is the soft inner part of the tooth that contains blood vessels and nerves. It plays a critical role in the tooth's health and sensitivity.

Limiting sugary and sticky foods is important because they can adhere to teeth and promote the growth of bacteria, leading to tooth decay and cavities.

Digestion begins in the mouth, where teeth chew and grind food into smaller pieces, mixing it with saliva to make it easier to digest.

After the food is chewed in the mouth, it travels down the oesophagus (food pipe) to reach the stomach for further digestion.

Chewing food well is important because it breaks food into smaller pieces, making it easier for digestive enzymes to work effectively and aiding in the overall digestion process.

There are four main types of teeth: incisors, canines, premolars, and molars. Each type serves a specific function in the process of eating.

In the stomach, food is mixed with digestive juices that further break it down into a semi-liquid form, preparing it for digestion in the small intestine.

The production of enamel is not a function of the digestive system; rather, it is a characteristic of tooth structure. The digestive system is involved in breaking down food, absorbing nutrients, and eliminating waste.

Brushing teeth twice a day is an effective way to maintain strong and healthy teeth. It helps remove plaque and food particles, thus preventing tooth decay and gum disease.
