Quizplus · Accepted Answer

The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs to be oxygenated. Therefore, the right atrium and right ventricle pump blood back to the lungs via the pulmonary artery. The mitral valve is located between the left atrium and left ventricle and prevents backflow of blood between those chambers. The aorta is the main artery that carries oxygen-rich blood from the left ventricle to the rest of the body. Capillaries are tiny blood vessels that allow for exchange of nutrients, gases, and waste products between the blood and tissues.
