The cardiovascular system consists of the heart and two vascular systems, the systemic and pulmonary circulations. The heart pumps blood through these two vascular systems – the low pressure pulmonary circulation in which gas exchange occurs, and then the high pressure systemic circulation, which delivers blood to individual organs, matching supply to metabolic demand. Blood pressure and flow are largely controlled by the autonomic nervous system, and are also influenced by surgery and anaesthetic drugs.
