THE CIRCULATORY SYSTEM

The circulatory system consists of the heart, blood vessels and blood. It moves blood through the heart and around the body. Blood gives our cells the oxygen and nutrients they need. Blood also collects waste products, such carbon dioxide, and takes them to the parts of the body which expel them.

SIGHT

Our eyes are the organs of sight. We can see different shapes and colours.

The pupils are black but the iris can be different colours.

Our eyes are very delicate and protected by the eyebrows, eyelashes and eyelids. These stop sweat and dust getting into our eyes.
