Question

Name the blood vessel which carries oxygenated blood.

• A. pulmonary veins
• B. anterior vena cava
• C. pulmonary arteries

Answer 1

The correct option is A

pulmonary veins

The correct option is A.

Explanation for the correct option:

1. Pulmonary veins collect oxygen-rich blood from the lungs and carry it to the heart.
2. The heart then distributes the blood to all of the body's organs and tissues.
3. The only veins in our body that carry oxygen-rich blood are the pulmonary veins.
4. While the other veins carry oxygen-depleted blood.
5. The four pulmonary veins (two from each lung) bring freshly oxygenated blood from the lungs to the left atrium.
6. Blood flows from the left atrium to the left ventricle, where it is ejected to supply oxygen and nutrients to all of the body's tissues.

Explanation of incorrect answers:

Option B:

1. A large vein that carries blood to the heart from other areas of the body.
2. The two large veins, the right and left brachiocephalic, join to form the anterior/superior vena cava.
3. The anterior vena cava carries blood that has been collected from the head, neck, chest, and arms and empties into the right atrium of the heart.

Option C:

1. The main pulmonary artery, also called the pulmonary trunk, is a vessel that emerges from the heart.
2. It is divided into the left and right pulmonary arteries, which carry blood into the lungs with a low oxygen content and a high carbon dioxide content.
3. The pulmonary circulation's function is to move carbon dioxide and oxygen from the blood in the body to the lungs' air during inhalation and exhalation.

Final answer: The blood vessel which carries oxygenated blood is the pulmonary veins.
