PATHOLOGY

Detailed explanation-1: -Generally, veins carry deoxygenated blood from the body to the heart, where it can be sent to the lungs. The exception is the network of pulmonary veins, which take oxygenated blood from the lungs to the heart.

Detailed explanation-2: -Veins are blood vessels located throughout your body that collect oxygen-poor blood and return it to your heart. Veins are part of your circulatory system. They work together with other blood vessels and your heart to keep your blood moving. Veins hold most of the blood in your body.

Detailed explanation-3: -Most veins usually carry deoxygenated blood from tissues back to the heart but exceptions are the pulmonary and umbilical veins, both of which carry oxygenated blood to the heart. Oxygenated blood from the lungs is circulated back to the heart through the pulmonary veins that drain into the left atrium.
