what do veins do?

Asked by rahulbharti | 15th May, 2009, 04:36: PM

Expert Answer:

Veins carry blood from various parts of the body to the heart. All veins except the pulmonary vein carry deoxygenated blood. Veins contain valves at intervals which allow blood flow in only one direction i.e. towards the heart.
