Solution:
Concept: - In a closed blood circulation system three types of blood vessels are present:
- Arteries: These carry pure oxygenated blood from the heart to different organs of the body.
- Veins: These carry impure deoxygenated blood from body organs to the heart.
- Capillaries: These are present in organs, and these are the vessels through which exchange takes place.
Explanation: - All the arteries carry pure blood except the pulmonary artery which carries impure blood.
- The pulmonary artery takes impure deoxygenated blood into the lungs from the right ventricle.
- Here the blood goes through capillaries adjacent to alveoli and becomes oxygenated as part of the respiration cycle.
- Thus, the correct option is ''Lungs''.
