Blood circulation. Illustration of major blood vessels in the human body,shown in a standing figure. The heart is seen in the chest,with pulmonary blood vessels of the lungs on either side. In the abdomen are two networks of renal blood vessels feeding the kidneys; in the brain are cerebral blood vessels. Arteries (red) carry oxygen-rich blood from the heart to the body; veins (blue) return deoxygenated blood to the heart. The average adult has about five litres of blood. At rest this volume of blood passes through the heart and around the body each minute | |
