The list of differences between veins and arteries says veins “rarely” pulsate and “mainly” carry deoxygenated blood. One vein is different from the rest. Which one?
pulmonary
The vein that is different from the rest is the pulmonary veins. Unlike other veins, the pulmonary veins carry oxygenated blood from the lungs to the heart.
To identify the vein that is different from the rest based on the given information, we need to focus on the two characteristics mentioned:
1. Pulsation: Veins "rarely" pulsate.
2. Carrying deoxygenated blood: Veins "mainly" carry deoxygenated blood.
It is important to note that while veins mainly carry deoxygenated blood, there is one exception called the pulmonary vein. The pulmonary vein is the only vein in the human body that carries oxygenated blood.
Therefore, the pulmonary vein is the vein that is different from the rest in terms of carrying oxygenated blood instead of deoxygenated blood.
