I believe the answer you are looking for is called a blood vessel. The system is called a circulatory system.
The veins carries the blood back to the heart using the circulatory system. It then stores the blood in the arteries and the heart pumps it back around the body.
The respiratory system oxygenates the blood and expels carbon dioxide and the heart pumps the oxygenated blood out to the body and collects the de-oxygenated blood and carries it back to the lungs.
The RIGHT VENTRICLE pumps the oxygen-poor blood through the pulmonary semilunar valve and into the pulmonary artery, which carries it to the lungs.
arteries
The cardiovascular system brings blood to the body. You have more than 50,000 miles of blood vessels in your body.
The circulatory system pumps the blood which carries the nutrients that the cells needs. The circulatory system gets the nutrients from the digestive system.
The cardiovascular system pumps blood throughout the body.The Nervous System of course.
right ventricle
pumps blood around the body which carries nutrients that are then absorbed into the cells.
Actually, the exchange of oxygen for CO2 happens in the lungs. The heart pumps the blood through the system.
The heart is also known as the blood-pump of the body. It pumps blood through the circulatory system to all parts of the body. The blood carries food and oxygen to the cells and carries away carbon dioxide and waste materials. --- The right hand side of the heart receives de-oxygenated blood from the body tissues, and pumps it to the lungs. The left-hand side of the heart receives oxygenated blood from the lungs and pumps it into the body, so that the oxygen can be delivered to cells.
