Identify the incorrect statement regarding pulmonary veins:
Pulmonary veins carry deoxygenated blood from the lungs to the heart.
Pulmonary veins carry oxygenated blood from the lungs to the heart.
Pulmonary veins carry deoxygenated blood from the heart to the lungs.
Pulmonary veins carry oxygenated blood from the heart to the lungs.
The pulmonary veins carry oxygenated blood from the lungs to the heart, which makes option 2 incorrect.
The pulmonary veins are responsible for transporting oxygen-rich blood from the lungs, where oxygen is obtained during the process of respiration, back to the heart. From the heart, this oxygenated blood is then pumped to the rest of the body via systemic circulation to supply oxygen to tissues and organs.
In contrast, the pulmonary arteries carry deoxygenated blood from the heart to the lungs, where it picks up oxygen and undergoes gas exchange before returning to the heart through the pulmonary veins.
Therefore, option 2 is the correct answer.
