As a subject matter expert in cardiovascular anatomy, I can provide you with the correct information regarding the vessels that carry oxygen-poor blood in the heart.
The
pulmonary arteries are the vessels that carry oxygen-poor blood from the heart to the lungs. Specifically, the
right ventricle of the heart pumps blood into the
pulmonary trunk, which then branches into the
left and right pulmonary arteries. These arteries transport the blood to the lungs where it picks up oxygen and releases carbon dioxide.
The
superior and inferior vena cava are also involved in carrying oxygen-poor blood, but they are not part of the heart itself. They bring deoxygenated blood from the upper and lower parts of the body, respectively, back to the
right atrium of the heart.
