Question

Which of the following is a blood vessel which enters the heart?

• A. Anterior vena cava
• B. Posterior vena cava
• C. Pulmonary veins
• D. All of the above

Answer 1

The correct option is D All of the above

Blood enters the heart through two large veins, the anterior and posterior vena cava, emptying oxygen-poor blood from the body into the right atrium. The pulmonary vein empties oxygen-rich blood, from the lungs into the left atrium.

So, the correct answer is 'All of the above'.
