Healthy heart. Coloured three-dimensional (3-D) computed tomography (CT) chest scan revealing a healthy heart (green & blue,lower centre) in the ribcage (purple & yellow). Above the heart are the ascending (red) and descending (light blue) aorta,as well as the pulmonary artery (orange) and the oesophagus (tan brown,upper left). The heart is a hollow muscle which pumps deoxygenated blood to the lungs through the pulmonary artery and oxygen- rich blood to the body through the aorta. Food travels down the oesophagus to the stomach. CT scans use X-rays to form "slice" images of the body,which a computer builds into a 3-D image | |
