Fascinating Fact:

Digestion starts in the mouth, where enzymes in saliva begin breaking down food.

In KS3 Science, the digestive system is studied to understand how food is broken down into nutrients. These nutrients provide energy, repair tissues, and keep the body functioning well.

Key Terms

Enzyme: A protein that speeds up chemical reactions, such as breaking food into smaller molecules.
Nutrient: A substance from food that the body needs for energy, growth, and repair.
Absorption: The process where digested food passes into the blood to be used by the body.

Frequently Asked Questions (Click to see answers)

Where does digestion begin in KS3 Science?

Digestion begins in the mouth, where teeth break food into smaller pieces and enzymes in saliva start breaking down starch into sugar molecules.

What is the role of enzymes in digestion?

Enzymes act as biological catalysts that speed up digestion by breaking large food molecules, like proteins and carbohydrates, into smaller, absorbable ones.

How are nutrients absorbed into the body?

Nutrients are absorbed in the small intestine, where tiny villi transfer them into the bloodstream to supply energy and materials for growth and repair.
