Remember veins back to the heart. This goes into the heart to deliver oxygen.
to the lungs
...to the lungs.
Blood leaves the pulmonary artery and travels into the lungs. In the lungs the blood releases carbon dioxide and picks up oxygen.
Remember arteries away from the heart. This goes into the lungs to pick up oxygen.
The Pulmonary arteries
Blood leaves the right side of the heart and goes to out the pulmonary trunk (a very large artery) to the pulmonary arteries (left and right) to the capillaries in the lungs and picks up oxygen.
Oxygen-poor blood leaves the heart via the pulmonary artery and is transported to the lungs for oxygenation. Once it picks up oxygen in the lungs, it returns to the heart through the pulmonary vein to be pumped out to the rest of the body.
to the lungs
The systemic arteriole, then the capillaries, the venule, the vein, the vena cava, the heart, the pulmonary artery, the pulmonary arterioles, capillaries, the pulmonary veins, the heart, into the aorta, and back into the artery.
There are two tubes that take blood out of the heart. These are the pulmonary artery and the aorta.
It flows through the pulmonary artery and towards the lungs where the blood will become oxygenated.
right atrium -> right ventricle -> pulmonary artery -> pulmonary vein -> left atrium -> left ventricle -> aorta
