Respratory systen
Blood flows through veins after delivering oxygen to the body.
Deoxygenated blood flows into the right atrium first. From there, it moves to the right ventricle, and then the pulmonary circulation.
Blood flows to the lungs through the pulmonary trunks which divides into the right and left pulmonary arteries. These transport blood to the air sacs of the lungs, where carbon dioxide in unloaded and oxygen is picked up. Then the blood flows back to the heart by the pulmonary veins.
With a double circulatory system, the heart can increase the pressure of the blood after the blood has picked up oxygen from the lungs. This means it can transport oxygen to the body tissues much quicker.
Different amounts of oxygen alter its color due to the high levels of iron in the hemoglobin. Coming from the lung region, blood is extremely oxygen-rich, making it a brighter red. When the oxygen is stripped away the blood turns blue.
It is called the pulmonary circulation, where blood travels to the lungs to receive oxygen and lose carbon dioxide, before returning to the heart.
The heart pumps blood to different parts of the body through small tubes called blood vessels. The human body has two circulatory systems. Pulmonary Circulation and Systemic Circulation. Pulmonary Circulation - blood flows from the heart to the lungs and then back from lungs to heart. Systemic Circulation - blood flows from the heart to other organs in the body and back from other organs to the heart.
None. Nerves are not part of the circulatory system. They receive nutrients and oxygen from the circulation like any other part of the body, but there is no blood that "flows from the nerves". Tracy Morton MD
Coronary circulation is the circulation of blood in the blood vessels of the heart muscle (the myocardium). The vessels that deliver oxygen-rich blood to the myocardium are known as coronary arteries. The vessels that remove the deoxygenated blood from the heart muscle are known as coronary veins.
"The circulation of blood through the body is often compared to a plumbing system with the heart as the pump and the veins, arteries, and capillaries as the pipes through which the blood flows."
Blood with no oxygen (the blood that flows to the heart picks up oxygen from the lungs).
Pulmonary circulation is blood supply to the lungs. This is important for two reasons. First, like all organs, the lungs have to have oxygen themselves in order to function. Second, blood has to go through the lungs in order to become oxygenated. The pulmonary vein is the only vein in the body that carries oxygenated blood. Systemic circulation is important for two reasons also. First, and simplest, is the fact that every cell in the body has to have oxygenated blood to function. Without oxygenated blood, the cells will begin to infarct, or die. Second, systemic circulation creates what's called perfusion pressure. Simply put, it's the pressure required to allow the organs to pull the oxygen from the blood. As blood pressure goes down, the body's ability to pull in oxygen from the blood also decreases.
