The low-pressure circuit from the heart (right atrium and right ventricle), through the lungs, and back to the heart (left atrium)constitutesthepulmonary circulation. Passage of blood through the left atrium, bicuspid valve, left ventricle,aorta, tissues of the body, and back to the right atr...
Your heart is an amazing organ. It continuously pumps oxygen and nutrient-rich blood throughout your body to sustain life. This fist-sized powerhouse beats (expands and contracts) 100,000 times per day, pumping 5 or 6 quarts of blood each minute, or about 2,000 gallons per day. So how ...

It is an involuntarily controlled system, meaning that an organism doesn't need to actively think about pumping blood throughout the body. Arteries carry blood away from the heart, while veins carry blood back to the heart. Both arteries and veins have muscular walls, but arteries have an ...
The structure of the heart also houses the biggest artery in the body – the aorta. The right and the left region of the heart are separated by a wall of muscle called the septum. The right ventricle pumps the blood to the lungs for re-oxygenation through the pulmonary arteries. The ...

to occur. Land vertebrates developed lungs, a new vein (thepulmonary vein) to take blood from them to the heart, and a double circulation, whereby the heart is effectively divided into two halves—one-half concerned with pumping incoming deoxygenated blood from the body to the lungs and the ...
The heart is an electric pump with the purpose of sending oxygen-rich blood through the arteries of the body to every organ and cell to allow them to function. The heart is a muscle and needs a constant supply of oxygen. There are three main arteries to the heart: the left anterior des...
