Answer and Explanation: The heart and circulatory system is described as a ‘double loop’ because it has two routes of circulation, one to body and one to the lungs.Click to see full answer. Besides, how does the heart function as a double pump?Your heart is a single organ, but it acts as a double pump. The first pump carries oxygen-poor blood to your lungs, where it unloads carbon dioxide and picks up oxygen. It then delivers oxygen-rich blood back to your heart. The second pump delivers oxygen-rich blood to every part of your body.One may also ask, what is double circulation in human beings? In human beings, the blood goes through the heart twice during each cycle i.e. the blood passes through the human heart two times to supply once to the whole body. So, it is called Double Circulation of blood. The left ventricle pumps oxygenated blood into aorta for systematic circulation. Similarly, you may ask, what are the two loops of blood flow? There are 2 primary circulatory loops in the human body: the pulmonary circulation loop and the systemic circulation loop. Pulmonary circulation transports deoxygenated blood from the right side of the heart to the lungs, where the blood picks up oxygen and returns to the left side of the heart.How does the blood flow through the heart step by step? Blood flows through your heart and lungs in four steps: The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle through the tricuspid valve. The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve.
