Artery Blood vessel that carries blood away from the heart.
Balanced Diet Eating a wide variety of foods to give us all the things that we need.

Egestion When faeces are pushed out of the anus.

Faeces Waste food material produced by the intestines.
Fat Substance found in food that is stored to be used for energy in the future. It also helps to keep heat in our bodies.

Protein Substance found in food that is used for growth and repair.

Saliva A digestive juice. It contains an enzyme that breaks down starch into sugar.
Salivary Glands Found in the mouth. It makes saliva.

Solvent A liquid that can dissolve other substances.
Starch Type of insoluble carbohydrate found in plants.
Stomach Organ containing strong acid which mixes food up and digests proteins.
Sugar Type of soluble carbohydrate. Glucose is an example of a sugar.
Tissue A group of cells of the same type all doing the same job.
Tissue Fluid A liquid that leaks out of capillaries carrying dissolved food and oxygen to cells.
Vein Blood vessel that carries blood towards the heart.
Villi Small finger-like parts of the small intestine. They increase the surface area so that digested food is absorbed more quickly. Singular = villus.
Vitamin Substance found in food that is needed in small quantities for health (e.g. vitamin C).
