The aorta.
The Vein does not bring blood to the Heart.
The role of the pulmonary circulation is to take blood that is poor in oxygen and load it up with oxygen. It also takes the carbon dioxide content of blood and gets rid of it, that is you exhale it. One role of the systemic cirulation to deliver oxygen rich blood to where it is needed. That is to say that cells need oxygen to do their work, the brain to think and the muscles to contract. They get their oxygen from the systemic circulation. But blood in the systemic circulation got its oxygen from being in the pulmonary circulation.
which blood vessel regulates systemic resistance?
the systemic systemic circulation
Pulmonary veins and artery together with their associated capillaries
yes except for the pulmonary artery which distributes unoxygenated blood to the lungs
The blood circulation in the Lungs, called the pulmonary circulation, is COMPLETELY a part of the general, systemic circulation of Blood.
The pulmonary artery is the primary vessel that carries blood to the lungs. Unlike the systemic circulation, the pulmonary artery carries deoxygenated blood.
coronary circulation
Pulmonary and systemic
The purpose of systemic circulation is to carry blood from the heart to the body. It then returns the blood back to the heart.
