Giraffe anatomy. Cutaway illustration showing the internal organs and anatomy of a giraffe (Giraffa camelopardalis), with the respiratory system highlighted (other organs faded out). The organs shown here are the digestive system (stomach and intestines), the lungs (pink), and the blood vessels (pale red). This even-toed ungulate mammal is the tallest living land animal and the largest ruminant. It can grow to a height of 5.5 metres and weigh over a tonne. Feeding mainly on the twigs and leaves of trees, it is found on the grasslands and scrublands of sub-Saharan Africa. The giraffe's circulatory system has adaptations related to its long neck and legs that enable it to feed on leaves that other animals cannot reach.
