Test: Digestive System- 1 - Class 4 MCQ

When the food enters the small intestine, more digestive juices are added to help digest it completely. This is where most of the digestion process happens before the nutrients are absorbed into the blood.

The process of digestion ends in our body when the undigested food leaves our body through a special opening called the anus. This is how our body gets rid of the food that it cannot use to give us energy and keep us healthy.

• The substance that is mixed with food in the mouth during chewing is Saliva.
• Saliva is produced from salivary glands.
• Saliva is important to lubricate your mouth.

• Digestion begins in the mouth.
• The food is ground up by the teeth and moistened with saliva to make it easy to swallow.

• When we eat our meal, our body needs time to digest the food properly.
• If we play or exercise right after eating, our body has to work hard to digest the food while we move around.
• This can make us feel uncomfortable and sometimes even sick.
• It's best to wait for a little while after eating before we start playing or exercising.
• This way, our body can focus on digesting the food, and we can stay healthy and feel good!

• The statement is True. The food pipe, also known as the oesophagus, is a tube that carries food from the mouth to the stomach.
• It helps in moving the chewed food from the mouth to the stomach for further digestion. So, when food is swallowed, it travels down the food pipe to reach the stomach.
• Remember, it's like a slide that helps the food go down into your belly!
