New words

Explanation

Your organs are packed in two main spaces. The chest holds the two lungs, with the heart between them. The ribs form a cage that protects them. Under the chest is the abdomen. The stomach is at the top left, and the small intestine and large intestine fill most of the rest. The liver is at the upper right. At the back, a kidney sits on each side. All these organs are linked by blood vessels, which carry blood to and from them. The organs work in teams: the lungs bring in oxygen, the heart pumps it, the digestive organs give nutrients, and the kidneys keep the blood clean. We draw organs as simple boxes, not as realistic shapes.

Worked examples
Marwan breathes in. The lungs fill with air. The heart pumps blood through the lungs, and the blood takes the oxygen. This is a team of lungs, heart and blood vessels.
Seif feels his ribs with his hand: they curve around his chest like the bars of a cage. The ribs protect the heart and lungs inside.
