Test: Food & Digestion - 1 - Class 4 MCQ

The small intestine is responsible for absorbing nutrients from the digested food and transporting them to the body.

The spleen is not a component of the digestive system. It is an organ involved in the immune system and blood filtration.

The digestion process begins in the mouth, where food is chewed and mixed with saliva.

Saliva contains enzymes that convert insoluble starch into soluble sugar, aiding in the digestion process.

The stomach churns the food and utilizes digestive juices to break down proteins into simpler forms.

The small intestine is divided into three sections: the duodenum, jejunum, and ileum.

The large intestine is responsible for absorbing water from the undigested food, leading to the formation of semi-solid waste.

The undigested food passes through the large intestine and is eliminated from the body through the anus as waste.

Food preservation involves various methods to extend the shelf life of food and maintain its nutritional value.

Boiling food at high temperatures is a method of food preservation that kills bacteria and other microorganisms.
