Verified step by step guidance

Step 1: Understand the anatomy of the heart and its chambers. The heart has four chambers: the right atrium, right ventricle, left atrium, and left ventricle. Blood flows from the right ventricle into a specific blood vessel.

Step 2: Recall the function of the right ventricle. The right ventricle pumps deoxygenated blood to the lungs for oxygenation. This means the blood vessel exiting the right ventricle must lead to the lungs.

Step 3: Identify the blood vessel that carries deoxygenated blood to the lungs. The pulmonary trunk is the large artery that exits the right ventricle and splits into the left and right pulmonary arteries, which transport blood to the lungs.

Step 4: Differentiate the pulmonary trunk from other vessels listed in the options. Pulmonary veins return oxygenated blood from the lungs to the left atrium, the superior vena cava brings deoxygenated blood from the upper body to the right atrium, and the aorta carries oxygenated blood from the left ventricle to the rest of the body.

Step 5: Conclude that the correct answer is the pulmonary trunk, as it is the blood vessel that exits the right ventricle and carries deoxygenated blood to the lungs.
