Digestion is the process of breaking down food into substances that can be absorbed into the blood.

The digestive system is a collection of organs that break down food.

A gland is a tissue or an organ that produces chemicals.

An adaptation is a feature that helps an organism to function and survive.

Fibre bulks up food so it can be moved through the digestive system more easily.

Absorption and transport of nutrients in humans

Pupils will learn how cells use sugar from digested food as a source of energy.

Pupils learned that particles of substances move within, into and out of cells by diffusion.

This unit examines the human digestive system, including the roles of tissues, organs, enzymes, and beneficial bacteria. It also focuses on evaluating risks, interpreting data, identifying patterns, and suggesting improvements to enhance the reliability of investigations.

List the parts of the digestive system in the order through which food moves.

churns food to break it into smaller pieces

rings of muscle contract and push food through

villi increase the surface area for faster absorption

Match the parts of the human digestive system with their adaptation.
